Abstract
The global prevalence of COVID-19 has caused many supply chain disruptions, which calls for firms to build resilient supply chains. Prior research primarily examined the effects of firm resources or capabilities on supply chain resilience (SCR), with limited attention given to the critical role of supply chain transformational leadership (SCTL). Based on social learning theory, we explore how SCTL impacts SCR via an ambidextrous business model and the moderating role of paradox cognition. We employ hierarchical regression analysis to verify the hypotheses with data from 317 Chinese firms. The results show that SCTL has a positive impact on proactive and reactive SCR, and the ambidextrous business model mediates this relationship. Furthermore, paradox cognition strengthens the effect of SCTL on the ambidextrous business model. This study contributes to literature and practices in the field of transformational leadership and SCR by providing unique insights into how to improve SCR from a leadership perspective.

Introduction
Affected by the global prevalence of COVID-19, frequent supply chain disruptions have occurred (Nikolopoulos et al., 2021; Jiang et al., 2023; Shen and Sun, 2023). Since supply chains are increasingly complex, firms are more likely to suffer from supply chain disruptions (Lechler et al., 2019; Spieske and Birkel, 2021; Xi et al., 2024). It will be difficult for a firm lacking resilient supply chains to survive and compete within a dynamic and uncertain condition. Supply chain resilience (SCR) reflects the capability of a system to maintain desirable functions before/during disruptions and/or timely recover to its normal functions after disruptive events (Gu et al., 2021). Understanding the enablers of SCR would help the firm better respond to potential risks caused by supply chain disruptions (Vanpoucke and Ellis, 2020).
Firm leaders could play critical roles in reducing disruption risk in supply chains and building a more resilient supply chain (Khunwishit et al., 2018). However, little research has checked the effect of transformational leadership within the supply chain context. We define supply chain transformational leadership (SCTL) as a continual influence that the focal firm demonstrates modeling values and reformative behaviors, which motivates its supply chain partners to act similarly with inspiration and close relationships.
While previous studies mainly focused on the roles of specific resources or capabilities on SCR, such as agility, redundancy, and collaboration (Al Naimi et al., 2021; Tukamuhabwa et al., 2015), the strategic role of SCTL has largely been ignored. Previous studies suggest that transformational leadership encourages employees’ reaction to changes in a firm (Peng et al., 2021) and increases team resilience (Dimas et al., 2018). Hence, high levels of SCTL could operate as role-modeling behaviors for the focal firm’s partners and foster a more resilient supply chain. According to social learning theory (Bandura, 1977; Brown et al., 2005), the focal firm with high levels of SCTL acts as a reliable role model whom its followers trust and attempt to emulate. That is to say, supply chain partners can learn transformative behaviors by observing the focal firm. As a result, the focal firm with high levels of SCTL acts as a benchmark for its supply chain followers to build a resilient supply chain. Therefore, we propose that SCTL may strengthen SCR.
Firms throughout supply chains often face conflicting objectives while implementing organizational learning to improve SCR (Lee and Rha, 2016). That is, they must balance different types of learning strategies, such as exploring potential opportunities to transform supply chains while also exploiting current resources to optimize supply chains. The tension of balancing exploitation and exploration is termed organizational ambidexterity (Kristal et al., 2010). According to an ambidexterity perspective (Aslam et al., 2022; Eng et al., 2023), the focal firm with high levels of SCTL prefers to deal with supply chain disruptions through both exploring external opportunities and exploiting internal resources. However, little is known about how SCTL affects SCR via organizational ambidexterity.
Our research devotes to filling this research gap through clarifying the mediating effect of an ambidextrous business model that encompasses both novelty and efficiency within the SCTL–SCR link. We define an ambidextrous business model as a firm’s boundary-spanning transaction mode developed to create and capture value by both balancing activities of redesigning a novel business model and reorganizing elements of an existing one. Specifically, a novelty-centered business model could help firms explore a new value proposition to meet changing demands in disruptions, whereas an efficiency-centered business model improves inter-organizational transaction efficiency by facilitating supply chain visibility and reducing transaction cost (Wei et al., 2017; Zott and Amit, 2008). Drawing on social learning theory (Ojha et al., 2018), the focal firm with high levels of SCTL may demonstratively build an ambidextrous business model by fostering a supportive organizational context. Then, the ambidextrous business model in the focal firm motivates other supply chain partners to emulate and actively take a similar business model, improving SCR through shared supply chain ambidexterity. In this manner, an ambidextrous business model may mediate the SCTL–SCR relationship.
Furthermore, the focal firm with paradoxical thinking and cognition could also influence its learning strategies (Brusoni and Rosenkranz, 2014). That is, paradoxical thinking and cognition would affect the focal firm’s attitude and identification towards tensions (explore or exploit) arising from its contrasting strategic agendas (Smith and Lewis, 2011). When the focal firm possesses high levels of paradox cognition, it is more likely to recognize and embrace tensions, making well-balanced strategic decisions through developing transformational leadership. Hence, we propose that paradox cognition enhances the impact of SCTL on an ambidextrous business model.
In sum, this study explores three questions to uncover the impact of SCTL on SCR. First, whether SCTL is positively related to SCR? Second, does ambidextrous business model mediate the SCTL–SCR relationship? Third, does paradox cognition strengthen the role of SCTL on ambidextrous business model? By answering the above questions, this study makes a contribution to research and practices in the field of transformational leadership and SCR.
Literature review and hypotheses development
Supply chain resilience
Resilience, a multidisciplinary construct originating from engineering, ecology, and psychology (Holling, 1973; Novak et al., 2021). Although most scholars have viewed resilience as an ability to resist and/or rebound from disruptive events (El Baz and Ruel, 2021; Namdar et al., 2018), there still lacks a normative definition widely accepted. Later, resilience is extended and applied to the field of social sciences, such as supply chain management and operational management. Due to the prevalence of COVID-19, resilience is particularly valued in global supply chains as supply chains become increasingly complex (Spieske and Birkel, 2021).
The major divergences of SCR concentrate on two aspects: influencing scope and attributive level. With regard to the influencing scope, some authors only treat SCR as a reactive capability (Brandon-Jones et al., 2014; El Baz and Ruel, 2021), while others propose that both reactive and proactive components are indispensable (Gu et al., 2021). With regard to the attributive level, SCR is often viewed as a firm’s capability (Ambulkar et al., 2015); however, it is more acceptable to belong to a whole supply chain system (Scholten et al., 2020). Hence, we define SCR as the capability of a system to maintain its expected functions before disruptions and timely recover to its normal functions during facing interruptions.
SCR has been segmented into various dimensions corresponding to different nodes, disruptive phases, or sub-capabilities. For example, Pournader et al. (2016) argue that SCR could be divided by the organizational boundary into supplier, internal, and customer resilience. Han et al. (2020) suggest that SCR could be classified into stages of readiness, response, and recovery. Jüttner and Maklan (2011) propose that flexibility, velocity, visibility, and collaboration are essential sub-capabilities comprising SCR. Following Cheng and Lu’s study (2017), we divide SCR into two dimensions: proactive and reactive SCR. Proactive SCR is the capability of a supply chain system to mitigate shocks and keep its normal state before/during possible disruptions. Reactive SCR means the capability of a supply chain system to quickly respond and return to its normal state after experiencing disruptions.
Although previous research has revealed diverse factors in formulating SCR (Razak et al., 2023; Scholten and Schilder, 2015), transformational leadership is rarely discussed. Prior studies mainly examine the roles of four groups of resources and capabilities in building SCR, including reengineering, collaboration, agility, and risk management culture (Belhadi et al., 2022). First, supply chain reengineering is positively related to SCR. Resources and capabilities, such as network structure, security, redundancy, efficiency, innovation, contingency planning, and market position, usually contribute to the realignment of structures and processes within supply chains (Han et al., 2020; Tukamuhabwa et al., 2017), which could help firms deal with new changes. Second, supply chain collaboration is valuable to build SCR. By developing information sharing, risk and revenue sharing, trust, communication, coordination, and integration, the cooperation among different supply chain partners becomes mutually high-quality (Ali et al., 2017; Dubey et al., 2021; Zhu et al., 2024). Third, supply chain agility facilitates the construction of SCR. Flexibility, velocity, visibility, ambidexterity, market sensitiveness, and disruption mitigation (El Baz and Ruel, 2021; Gu et al., 2021; Jain et al., 2017; Kochan and Nowicki, 2018) can increase the responsiveness of a supply chain system when facing dynamic business environment. Fourth, supply chain risk management culture, which involves risk awareness, knowledge management, and training and development of a risk management team, can create a proper culture atmosphere in favor of SCR (Belhadi et al., 2022).
Beyond four fostering factors, some research has also identified the interactive effects of mixed resources or capabilities on SCR, like industry 4.0 technologies, social capital, leadership, and business model (Belhadi et al., 2024; Gölgeci and Kuivalainen, 2020; Shashi et al., 2020; Shin and Park, 2021). However, we still lack knowledge about the strategic role of transformational leadership in fostering SCR. Antecedents of SCR in existing literature are shown in Table 1.
Supply chain transformational leadership and supply chain resilience
Transformational leadership refers to leaders’ suitable behaviors that drive their followers’ reformative behaviors through continuous motivation and partnership (Bass, 1985, 1999). Existing literature demonstrates that transformational leadership could affect employee attitude (Peng et al., 2021) and team resilience in a firm (Dimas et al., 2018), while the strategic role of transformational leadership across an entire supply chain system needs more explanation. According to social learning theory (Brown et al., 2005), we regard the focal firm with high levels of SCTL as a credible role model whom other supply chain partners respect, trust, and emulate. In this manner, other supply chain partners are likely to learn transformative behaviors by observing the focal firm.
We view the development of SCTL as a role modeling-learning process. That is, the focal firm with high levels of SCTL has an exemplary influence on other supply chain partners via observing and learning from benchmarks. Specifically, SCTL includes three elements: inspiration, intellectual stimulation, and individualized consideration (Defee et al., 2010). Inspiration implies that the focal firm with high levels of SCTL often articulates a compelling vision about a desirable future for the supply chain system. The focal firm, with intellectual stimulation, tends to stimulate other supply chain partners to solve issues by adopting creative and innovative methods. Individualized consideration helps the focal firm understand differentiated demands of supply chain followers, and assists them respectively. Based on social learning theory (Bommer et al., 2005), the focal firm’s transformative behaviors benefit its followers by the conveyance of competence. Before/during disruptive events, the focal firm clarifies a reliable vision and motivates followers to observe what it does to improve firm resilience. Targeted support makes it easier for other supply chain partners to master and emulate the focal firm’s resilient actions. In addition, coordination and trust among firms are developed in the social learning process (Mostafa, 2019), constructing closer supply chain relationships. Therefore, SCTL could enhance the proactive dimension of SCR.
The focal firm with high levels of SCTL would not only strengthen the proactive dimension of SCR, but also contribute to the reactive dimension of SCR. Drawing on social learning theory (Bommer et al., 2005), the focal firm’s transformative behaviors increase the self-efficacy of other supply chain partners. After supply chain disruptions, the focal firm demonstrates its response and encourages followers to achieve quick recovery through their differentially new insights. Besides, as firms in the supply chain are closely connected, all members’ resilient actions would transform into SCR when there are common goals and effective interactions (Gölgeci and Kuivalainen, 2020). In this manner, SCTL contributes to the reactive aspect of SCR. Hence, we hypothesize:
H1: SCTL has a positive influence on (a) proactive dimension and (b) reactive dimension of SCR.
Supply chain transformational leadership and ambidextrous business model
Ambidexterity is a special dynamic ability balancing exploration and exploitation simultaneously (Kristal et al., 2010; Lee and Rha, 2016). Previous literature has identified that different leadership styles, such as transformational leadership, could foster ambidexterity in firms (Jansen et al., 2008; Tarba et al., 2020). Ambidextrous business model means a firm’s boundary-spanning transaction mode developed to create and catch business value by balancing activities of redesigning novel governance, content, and structure and reorganizing elements of an existing business model. Miller (1996) identifies that novelty and efficiency are classic themes of designing business models. Specifically, a novelty-centered business model aims to create value and catch potential opportunities by redesigning a new business model, while an efficiency-centered business model devotes to increasing efficiency and decreasing operational cost by reconstructing the current business model (Feng et al., 2022; Wei et al., 2017; Zott and Amit, 2008). Under the context of plurality, change, and scarcity, leaders in firms have more intentions to make decisions from an ambidexterity perspective (Smith and Lewis, 2011). According to social learning theory (Wang and Feng, 2023), leaders in the focal firm with high levels of SCTL tend to express a committed attitude and take exemplary actions to maintain balancing operations. In other words, employees would be guided to conduct certain transformative behaviors, raising a flexible organizational culture with their leaders’ values.
SCTL, which is viewed as a role model-building process, includes three components: inspiration, intellectual stimulation, and individualized consideration (Defee et al., 2010). First, the focal firm with high levels of SCTL often articulates a compelling vision and sets high-quality standards. Inspiration by the focal firm’s leaders shows necessary confidence in their subordinates’ abilities and encourages employees to recognize the importance of individual effort in creating and capturing value through exploring and exploiting business opportunities. Additionally, the focal firm’s leaders promote collective goal-setting and collaboration among employees based on a shared vision, creating a supportive organizational context characterized by discipline, stretch, and trust (Ojha et al., 2018; Xi et al., 2023). Second, the focal firm with high levels of SCTL pays much attention to meeting emerging challenges. Intellectual stimulation by the focal firm’s leaders demonstrates transformative ideas and stimulates their employees to provide new insights under a challenging but supportive atmosphere, increasing organizational creativity and contributing to a stretch context (Elkins and Keller, 2003). Third, the focal firm with high levels of SCTL actively understands and helps its internal members. Individualized consideration by the focal firm’s leaders offers differentiated support via one-to-one knowledge exchange and creates a heartwarming condition that promotes more assistance among employees, fostering a culture of support and trust (Bommer et al., 2005). While a supportive organizational context is developed (Pan et al., 2021), a firm with high levels of SCTL prefers to design an ambidextrous business model. Thus, we hypothesize:
H2: SCTL has a positive influence on an ambidextrous business model.
Ambidextrous business model and supply chain resilience
The development of an ambidextrous business model could be recognized as a role model-engaging process. According to social learning theory (Wang and Feng, 2023), the focal firm with high levels of ambidextrous business model would serve as an example that provides a flexible business model for its followers. Then, supply chain followers are likely to trust and attempt to emulate the focal firm’s business model when sensing or experiencing frequent supply chain disruptions.
In detail, the focal firm with a high level of ambidextrous business model shows its supply chain partners how to maintain agility before/during disruptions through a proper organization arrangement. A novelty-centered business model could help other firms realize that they must create and capture value through designing new activities of governance, content, and structure to predict/respond to changing environments before/during disruptions. An efficiency-centered business model guides followers to continuously change the current supply chain into a more robust system (Wei et al., 2017; Zott and Amit, 2008). Besides, when all firms with high levels of ambidextrous business models tend to balance novelty and efficiency simultaneously, they would contribute to a more robust supply chain by preventive supply chain ambidexterity. Therefore, the ambidextrous business model enhances the proactive dimension of SCR.
The focal firm with high levels of the ambidextrous business model provides other supply chain members a valuable frame to quickly react after disruptions as well. Specifically, a novelty-centered business model stimulates other firms to adopt new ideas and norms in solving issues after disruptive events, improving their adaptability and responsiveness. An efficiency-centered business model helps followers achieve greater transaction efficiency and lower transaction costs, facilitating the adjustment of actions and strategies to rapidly respond to disruptions. In addition, firms with high levels of ambidextrous business models jointly balance novelty and efficiency, establishing a more resilient supply chain through responsive supply chain ambidexterity. SCTL contributes to the reactive dimension of SCR. Hence, we hypothesize:
H3: Ambidextrous business model has a positive influence on (a) proactive dimension and (b) reactive dimension of SCR.
In sum, the ambidextrous business model serves as a proper mediator within the role modeling-learning process. Drawing on social learning theory, the focal firm with high levels of SCTL demonstrates an ambidextrous business model through fostering a supportive organizational context. And then other supply chain partners would actively learn and emulate the focal firm’s typical business model based on their trust and common values, improving SCR by supply chain ambidexterity. An ambidextrous business model could transform SCTL into proactive and reactive dimensions of SCR. Thus, we hypothesize:
H4: Ambidextrous business model mediates the relationship between SCTL and (a) proactive dimension and (b) reactive dimension of SCR.
The moderating role of paradox cognition
Paradox cognition refers to an epistemic framework and process recognizing and juxtaposing contradictory demands, which could make latent tensions within organizations more explicit (Smith and Tushman, 2005). The focal firm with paradoxical thinking and cognition could influence learning strategies (Brusoni and Rosenkranz, 2014; Sheng et al., 2023). That is, paradox cognition may affect the focal firm’s attitude and identification towards tensions (explore or exploit) arising from its contrasting strategic agendas (Smith and Lewis, 2011). Based on social learning theory (Bandura, 1977), when the focal firm possesses high levels of paradox cognition, it is more likely to recognize the importance of ambidexterity. In this manner, leaders’ transformative behaviors in the focal firm with high levels of SCTL would be more easily accepted and emulated by employees to balance both explorative and exploitive learning activities (Han et al., 2022), which may help build an ambidextrous business model. By contrast, when the focal firm has low levels of paradox cognition, it tends to choose either novelty or efficiency in designing a business model. The SCTL-ambidextrous business model relationship becomes less important because contradictions in the focal firm are latent. Hence, we hypothesize:
H5: Paradox cognition enhances the impact of SCTL on an ambidextrous business model.
Combining the hypotheses above, we build a conceptual model to check the influence of SCTL on SCR (including proactive and reactive SCR), the mediating role of the ambidextrous business model within the SCTL–SCR relationship, and the moderating effect of paradox cognition. The conceptual model is illustrated in Fig. 1.
Research design
Procedures and data collection
We gathered data from Chinese manufacturers. Affected by the COVID-19 pandemic, manufacturing firms in China suffered from many supply chain disruptions, prompting leaders to realize the necessity of keeping a resilient supply chain (Lin et al., 2021; Shen and Sun, 2023). It is a challenging objective for manufacturing firms in China as they account for a large share of total exports in the global supply chains. Thus, China provided an appropriate context to explore the antecedents of SCR.
Due to the regional imbalanced characteristic of the Chinese economic force and transportation network (Feng et al., 2019; Hosseini et al., 2019), we selected sampling firms in five typical provinces: Guangdong, Jiangsu, Shandong, Henan, and Inner Mongolia. Guangdong, Jiangsu, and Shandong, in the eastern coastal areas of China, had relatively high levels of economic force and transportation networks. Henan, in the middle area of China, had average levels of economic force and transportation network. By contrast, Inner Mongolia, in the north and west of China, had relatively low levels of economic force and transportation network.
We adopted three steps to design a questionnaire. First, 12 firm executives, including the chief executive officer, general manager, or vice president, were interviewed to confirm the content validity of our study issue. All these individuals were required to be knowledgeable about their firms’ internal operations as well as external partnerships. Second, an initial questionnaire was developed through literature and expert review, translation, and back-translation. Third, a pre-test with another 20 executives was conducted to provide useful suggestions for modification, forming the formal questionnaire.
We randomly chose 200 firms in each province above and sought cooperation via a cover letter introducing the research intention. All participants were ensured confidentiality. Invitations were sent through emails or telephones, and 435 firms agreed to join our survey total. To mitigate common method bias (CMB), we split each questionnaire into two parts (including parts A and B) and invited different respondents in each firm to complete one part respectively. Part A featured demographic characteristics, competitive intensity, SCTL, novelty-centered business model, and SCR, whereas part B included paradox cognition and efficiency-centered business model.
We distributed and received back the questionnaires through emails from May 2020 to December 2020. 317 valid questionnaires were gathered, with an effective response rate of 72.9%. The final sample included 72 firms in Guangdong, 62 firms in Jiangsu, 67 firms in Shandong, 56 firms in Henan, and 60 firms in Inner Mongolia. The average working experience of 634 respondents was 7.19 years. 64.8% of our respondents held the posts of chief executive officer, general manager, or vice president, and 35.2% were operations directors. The detailed features of sampled firms are presented in Table 2.
We utilized two steps to verify non-response bias (Armstrong and Overton, 1977). First, firm size and ownership were compared for the nonresponding and responding firms. Second, differences in firm size, firm age, industry, and ownership between the early and late responses were also examined. These results of the independent t-test suggested that non-response bias in this study was not a serious issue.
Measures
We selected the seven-point Likert scale adopted or adapted from previous studies to measure all constructs in the questionnaire (1 = strongly disagree, 7 = strongly agree).
Supply chain transformational leadership
A refined seven-item scale from Defee et al. (2010) was applied to measure SCTL. SCTL was operationalized as respondents’ perceptions of their firms’ influences, which are often the outcome of behavioral factors, including inspiration, intellectual stimulation, and individualized consideration.
Paradox cognition
A seven-item scale from Smith and Lewis (2011) was used to measure paradox cognition. Respondents were requested to evaluate the degree of their own firms’ dual awareness when making strategic decisions in the last three years.
Ambidextrous business model
A ten-item scale and a nine-item scale were adjusted by Zott and Amit (2007) to measure the novelty-centered business model and efficiency-centered business model in turn. Additionally, the average value of these two variables was calculated to measure the ambidextrous business model. This approach not only kept convenience to reserve and made logical interpretations for the useful information from both parts but reflected the nature of ambidexterity–seemingly contradictory yet coexisting tensions (Lubatkin et al., 2006; Zhang et al., 2015).
Supply chain resilience
Following Cheng and Lu (2017), SCR was divided into two dimensions: proactive and reactive SCR Two altered four-item scales were adopted for proactive and reactive SCR separately (Ambulkar et al., 2015; Brandon-Jones et al., 2014; Wieland and Wallenburg, 2013).
Control variables
To mitigate the roles of other factors on analytical results as much as possible, we controlled five demographic characteristics, including firm size, firm age, industry, ownership, and competitive intensity (Ambulkar et al., 2015; Gölgeci and Ponomarov, 2015). Firm age and firm size were measured by the natural logarithm of the number of years since foundation and the natural logarithm of the number of employees, respectively (Li et al., 2008). One dummy variable was to control industry (1 = high-tech firm, 0 = otherwise), and two dummy variables (including state-owned and collective firms and private firms) were to control ownership. A four-item scale was adjusted by Jaworski and Kohli (1993) to measure competitive intensity.
Reliability and validity
First, we did a reliability test and explorative factor analysis (EFA). All constructs revealed high reliability with a Cronbach’s alpha value of more than 0.7 (Flynn et al., 1990). Seven principal components were extracted, which was consistent with constructs in the scales (Table 3). Second, we made a confirmatory factor analysis (CFA) by AMOS 24.0 to ensure validity. The results indicated that the measurement model had good fit indices: χ²/df = 2.034; RMSEA = 0.057; CFI = 0.928; NNFI = 0.923; SRMR = 0.038. All constructs’ composite reliability (CR) was more than 0.7, with item loadings varying from 0.760 to 0.939, and all average variance extracted (AVE) values were more than 0.5 (Table 3). Thus, the results indicated sufficient convergent validity. Besides, the comparison between shared variances of constructs and the square root of AVE demonstrated that all correlations were less than the corresponding square roots of AVEs (Table 4), identifying acceptable discriminant validity. Tables 3 and 4 reported the measure items, reliability, and validity assessment.
Common method bias
We utilized three means to test CMB. First, Harman’s single-factor test was conducted, revealing that there were seven principal components (Table 3), and no single factor accounted for most variances in these measures. Second, the fit indices of CFA between the actual seven-factor model and the one-factor model were compared, indicating that the one-factor model got significantly worse fit indices. Third, another common method factor was supplemented to the seven-factor CFA model above and it discovered that the fit indices did not change significantly. As a result, there was no serious CMB.
Results
We adopted hierarchical regression analysis and the bootstrapping method by SPSS 23.0 to examine the research hypotheses. First, the effect of SCTL on SCR was examined. Then, the influence of SCTL on the ambidextrous business model, the effect of the ambidextrous business model on SCR, and the mediating impact of the ambidextrous business model within the SCTL–SCR link were tested. Finally, the moderating effect of paradox cognition in the SCTL–ambidextrous business model relationship was examined. Table 5 reports the results of the hierarchical regression model.
To minimize possible multicollinearity, we generated an interaction with mean-centering of both the independent variable and the moderating variable (Aiken and West, 1991). The maximal value of the variance inflation factor (VIF) is 1.739, which is much less than the recommended cut-off of 10. Thus, the multicollinearity is not serious.
H1a and H1b predict the positive impact of SCTL on both dimensions of SCR. Models 5 and 9 in Table 5 show that SCTL has a significantly positive effect on the proactive dimension (β = 0.122, p < 0.05) and reactive dimension (β = 0.166, p < 0.01). Therefore, H1a and H1b are supported.
H2 predicts the positive influence of SCTL on the ambidextrous business model. Model 2 in Table 5 indicates that SCTL has a significantly positive impact on ambidextrous business models (β = 0.140, p < 0.05). Hence, H2 is supported.
H3a and H3b predict the positive role of the ambidextrous business model on both dimensions of SCR. Models 6 and 10 in Table 5 suggest that the ambidextrous business model has a positive effect on the proactive dimension (β = 0.241, p < 0.001) and reactive dimension (β = 0.256, p < 0.001). Therefore, H3a and H3b are supported.
H4a and H4b hypothesize that the ambidextrous business model mediates the relationships between SCTL and two dimensions of SCR. According to Baron and Kenny (1986), Models 2, 5, and 7 in Table 5 jointly demonstrate that the ambidextrous business model (β = 0.228, p < 0.001) fully mediates the relationship between SCTL (β = 0.090, p > 0.1) and proactive dimension, which supports H4a. Similarly, Models 2, 9, and 11 in Table 5 collectively exhibit that the ambidextrous business model (β = 0.237, p < 0.001) partially mediates the relationship between SCTL (β = 0.133, p < 0.05) and reactive dimension, which supports H4b.
To ensure the robustness of the results, we further used the PROCESS macro to conduct a bootstrapped mediation analysis. As depicted in Table 6, the results keep consistency with the corresponding results in Table 5, ensuring the effectiveness of analytical findings before.
H5 hypothesizes that paradox cognition strengthens the impact of SCTL on the ambidextrous business model. Model 3 in Table 5 presents that the interaction of SCTL and paradox cognition is significantly positive (β = 0.094, p < 0.1), which supports H5. Moreover, we applied a simple slope analysis to verify the moderating effect of paradox cognition so that a clearer explanation could be given. As illustrated in Fig. 2, when levels of paradox cognition are higher, the role of SCTL in the ambidextrous business model becomes stronger. Hence, the result further supports a strengthened effect of paradox cognition in the SCTL–ambidextrous business model relationship.
Discussions and implications
Discussions
This study intends to verify the impact of SCTL on both dimensions of SCR (including proactive and reactive SCR) through the ambidextrous business model and the moderating role of paradox cognition. Our results exhibit that SCTL has a positive influence on proactive and reactive SCR. This finding is similar to studies that explore the effect of leader–member exchange on network resilience performance in the supply chain context (Shin and Park, 2021) or the effect of transformational supply chain leadership on operational performance (Defee et al., 2010). However, these studies only emphasize the necessity of inter-organizational relationships and capabilities within the influential process of supply chain leadership on supply chain performance. Our results show that SCTL contributes to proactive and reactive SCR in a social learning process where both firm resilience and supply chain collaboration are indispensable parts.
Our results demonstrate that an ambidextrous business model mediates the impact of SCTL on SCR. This finding is inconsistent with existing studies about the antecedents or consequences of business models (Schoemaker et al., 2018; Shashi et al., 2020). One possible explanation is that the ambidextrous business model aims at designing new business models to capture and create value while also reconfiguring new combinations to improve transaction efficiency. Our results also indicate that the ambidextrous business model fully mediates the relationship between SCTL and proactive SCR while partially mediates the relationship between SCTL and reactive SCR. That is, the ambidextrous business model occupies a more important position in the SCTL-proactive dimension link. A possible reason could be that compared with intellectual stimulation, the influence of inspiration and individualized consideration is more dispersive within a longer time, improving the necessity of an ambidextrous business model. These results provide new insights to realize how SCTL enhances SCR.
In addition, we identify that paradox cognition strengthens the effect of SCTL on an ambidextrous business model. When the focal firm has high levels of paradox cognition, it tends to recognize the importance of ambidexterity. In this manner, the focal firm’s transformative behaviors would be more easily accepted and emulated by employees to balance both explorative and exploitive learning activities (Han et al., 2022), building an ambidextrous business model. This outcome verifies our research hypothesis, indicating the importance of paradox cognition in the SCTL–ambidextrous business model link.
Theoretical contributions
This study contributes to managerial research in three aspects. First, we enrich the antecedents of SCR by confirming the role of SCTL. Existing studies emphasize the impacts of specific resources or capabilities on SCR, such as agility, redundancy, and collaboration (Al Naimi et al., 2021; Tukamuhabwa et al., 2015), while the strategic effect of SCTL is rarely discussed. Previous literature has identified that transformational leadership could improve employee attitude (Peng et al., 2021) and team resilience (Dimas et al., 2018) at the firm level. Our research extends the concept of transformational leadership to the whole supply chain system and proposes that the focal firm with high levels of SCTL can improve proactive and reactive SCR. Hence, we contribute to the field of SCTL and SCR.
Second, we reveal the ‘black box’ of how SCTL impacts SCR by examining the mediating role of the ambidextrous business model. Existing studies reveal the influence of transformational leadership on organizational ambidexterity (Eng et al., 2023) and the impact of organizational ambidexterity on SCR (Aslam et al., 2022), while we still lack understanding of how SCTL affects SCR. Previous literature has demonstrated that redesigning a supply chain with high levels of concentration plays a significant role in protecting firm performance when suffering from disruptions (Liu et al., 2023). Hence, we contribute to the SCTL and SCR literature by showing a partial mediating effect of the ambidextrous business model in the SCTL–proactive SCR relationship and a fully mediating effect of ambidextrous business model in the SCTL–reactive SCR relationship.
Third, we clarify the boundary condition for the SCTL–ambidextrous business model relationship by examining the moderating effect of paradox cognition. Existing studies show that the efficiency of the learning process would be influenced by external stakeholders (Song et al., 2020; Wang and Feng, 2023), while the interactive role of internal factors is largely ignored. Previous literature has argued that organizational learning may be influenced by paradoxical thinking and cognition (Brusoni and Rosenkranz, 2014). Our findings suggest that paradox cognition would affect the focal firm’s attitude and identification towards tensions (explore or exploit) arising from its contrasting strategic agendas. Under high levels of paradox cognition, the focal firm is more likely to recognize and embrace tensions, making well-balanced decisions. Thus, the efficiency of social learning from SCTL to ambidextrous business model improves, which further emphasizes the necessity of developing paradox cognition within the learning process.
Managerial implications
This study offers three suggestions for managerial practice. First, managers should undertake leading roles and encourage member firms within the supply chain to improve SCR. In a dynamic and uncertain context, the focal firm with high levels of SCTL is effective to motivate its supply chain partners’ transformative behaviors. Managers should develop a reliable role model whom their followers trust and attempt to emulate. They should also develop two types of SCR, including proactive and reactive SCR. Additionally, they should articulate a compelling vision for all supply chain members, providing individualized training to meet the differentiated needs of firms and stimulating supply chain partners to create new insights with a supportive and challenging atmosphere.
Second, managers should establish an ambidextrous business model in firms. The focal firm with high levels of SCTL often demonstrates an ambidextrous business model by fostering a supportive organizational context. Managers should design an ambidextrous business model balancing both novelty and efficiency. Furthermore, they are suggested to motivate other supply chain followers to learn and emulate the focal firm’s transformative behaviors through a shared system vision, promoting communication and coordination among supply chain members.
Third, managers should foster a paradox cognition framework within their firms. Under high levels of paradox cognition, the focal firm is more likely to recognize the importance of ambidexterity and solve tensions from an ambidexterity perspective. Transformative behaviors of the focal firm would be more easily accepted and emulated by its employees. Managers should provide a proper organizational context for employees to improve their paradoxical thinking and cognition to quickly respond to disruptions.
Conclusion and limitations
Drawing on social learning theory, this study clarifies the impact of SCTL on SCR. Our findings reveal that SCTL has a positive influence on both proactive and reactive SCR. In addition, the ambidextrous business model fully mediates the relationship between SCTL and proactive SCR while also partially mediating the relationship between SCTL and reactive SCR. Paradox cognition strengthens the effect of SCTL on the ambidextrous business model.
This study has a few limitations, of course. First, we must demonstrate the effect of SCTL on SCR. Future research could try investigating the roles of other factors, such as transactional leadership to enrich antecedents of SCR. Second, this study only explores the mediating role of the ambidextrous business model between SCTL and SCR. In the future, other possible realization paths from the configurational perspective should be verified (Feng and Sheng, 2023). Third, we must identify the moderating impact of paradox cognition within the SCTL–ambidextrous business model relationship. Scholars are suggested to discover more possible boundary conditions like dynamic environment, and build a moderated mediation model to further explore the roles of potential moderators.
