## 3 Literature Review
### Moderating Effect of Digital Capability  
Recent academic research has extensively explored the moderating effects of digital capability in organizational management. Existing literature highlights the significant impact of digital capability across various fields and contexts, primarily in the following areas:  
(1) Organizational Performance and Digital Transformation  
Research demonstrates that digital capability significantly influences organizational performance. [PERSON] et al. (2023) [61] identified that dynamic capabilities improve employee and organizational performance via workplace digital transformation. [PERSON] (2022) [62] confirmed that digitalization enhances the positive effects of dynamic capabilities on SME performance. [PERSON] et al. (2023) [63] highlighted that digitalization boosts employee resilience, strengthening the link between task challenges and performance, especially during COVID-19. [PERSON] et al. (2023) [64] stressed the moderating role of digital business model maturity in transforming digital platform capability into SME growth. [PERSON] and [PERSON] (2023) [65] observed that digitalization's moderating effect on renewable energy integration intensifies beyond a critical threshold. [PERSON] et al. (2023) [66] validated rural digitalization's positive moderating role in shaping the environmental impact of green mergers and acquisitions.  
(2) Innovation and Institutional Environment  
[PERSON] et al. (2022) [67] examined how the institutional environment influences operations in a digital context, finding that government digitalization significantly moderates the technological entrepreneur ecosystem, with digital networks and innovation culture exerting a notable influence on entrepreneurial environments. [PERSON] et al. (2024) [68] used SEM to show that digital capability strengthens the relationship between institutional pressures and triple-bottom-line performance while indirectly enhancing this effect through environmental, social, and governance strategies.  
(3) Supply Chain Management and Performance  
[PERSON] and [PERSON] (2021) [69] showed that supply chain digitalization positively moderates the link between supply chain integration and firm performance. Similarly, [PERSON] et al. (2018) [70] found that trade digitalization moderates the relationship between supply chain finance and firm performance. [PERSON] et al. (2022) [71] found that digitalization levels in family firms moderate the impact of antecedents on internationalization intent. [PERSON] and [PERSON] (2024) [72] highlighted that human factor management's impact on productivity is amplified in digitalized environments, especially in areas beyond performance evaluation. [PERSON] et al. (2024) [73] highlighted the impact of relational embeddedness on supply chain transparency and confirmed that digitalization enhances the positive effects of supplier concentration. [PERSON] et al. (2024) [74] investigated how digital capability positively contributes to mitigating pandemic disruptions, thereby boosting firm resilience. Finally, [PERSON] et al. (2023) [10] noted that data analytics significantly reduce supply chain uncertainty by improving information processing capabilities, thereby enhancing SCR.  
These studies collectively validate the moderating role of digital capability across various fields. However, its subdimensions (digital infrastructure capability, digital analysis capability, and strategic support capability) require further investigation in the context of SCR. Based on the reviewed literature, we propose the following hypotheses:  
**H2:**: _Digital capability positively moderates the relationship between supply chain risk management and SCR._
**H3:**: _(a) Digital infrastructure capability, (b) digital analysis capability, and (c) strategic support capability exert varying degrees of positive moderating effects on the relationship between supply chain risk management and SCR._  
In summary, the theoretical framework proposed in this paper is shown in Figure 2.
