专精特新"小巨人"企业培育政策与供应链韧性OACHSSCD

Building a more resilient supply chain system is an imperative choice for China to withstand external risk shocks and uncertainties.Given the intricate input-output relationships among global economies,any risk shock or uncertainty could potentially disrupt China's supply chains.Particularly notable is the fact that Chinese enterprises have long faced significant challenges,including a lack of key core technologies and interruptions in external technology supply.Meanwhile,as an important institutional arrangement for promoting the optimization and upgrading of industrial and supply chains,the specialized,refined,distinctive,and innovative(SRDI)"small giant"enterprise cultivation policy plays a crucial role in continuously identifying and nurturing supply chain node enterprises with outstanding capabilities across various dimensions.However,existing studies have largely overlooked the close causal relationship between the SRDI"small giant"enterprise cultivation policy and supply chain resilience. This study first constructs a theoretical framework based on supply chain resilience theory,the resource-based view,and dynamic capability theory to analyze how the SRDI"small giant"enterprise cultivation policy influences supply chain resilience.Then,using panel data from A-share listed companies in Shanghai and Shenzhen from 2015 to 2023,this study treats the SRDI"small giant"enterprise cultivation policy as a quasi-natural experiment and employs a multi-period difference-in-differences model to evaluate its impact on supply chain resilience.The results demonstrate that:First,the SRDI"small giant"enterprise cultivation policy significantly enhances supply chain resilience.Second,driving cross-regional investment expansion,promoting a competitive position leap,and facilitating technological path expansion are key mechanisms through which the policy influences supply chain resilience.Third,the positive effects of this policy are only evident in non-state-owned enterprises,advanced manufacturing cluster enterprises,high-tech industry enterprises,and high-growth enterprises.Fourth,the SRDI"small giant"enterprise cultivation policy has an inhibitory effect on inter-firm technology spillovers,but its supply chain resilience-enhancing effect not only promotes inter-firm technology spillovers but also offsets the inhibitory effect. Compared with existing literature,this paper makes three marginal contributions.First,it integrates the SRDI"small giant"enterprise cultivation policy and supply chain resilience into a unified analytical framework,validating and expanding the scope of research on the microeconomic effects of the SRDI"small giant"enterprise cultivation policy.Second,in terms of theoretical logic,this paper analyzes the underlying mechanisms through which the SRDI"small giant"enterprise cultivation policy influences supply chain resilience from three dimensions:cross-regional investment expansion,competitive position leap,and technological path expansion,thereby deepening the theoretical understanding of the relationship between the policy and supply chain resilience.Finally,this paper highlights the technology spillover-suppression effect of the SRDI"small giant"enterprise cultivation policy,providing new empirical evidence for government policy regulation and optimization. This study provides decision-making reference for policymakers to accelerate the cultivation of SRDI enterprises and continuously and steadily enhance supply chain resilience.Specifically,governments should timely adjust enterprise selection criteria and provide essential market-oriented services for enterprises;enterprises must strengthen collaboration across the upstream and downstream of the supply chain,and foster a collaborative symbiotic ecosystem through measures such as building industrial alliances and promoting industry-academia-research cooperation.
