摘要
美国不断对中国实施科技“脱钩断链”,维护中国国内企业供应链韧性的需求更加迫切。以2010—2022年中国A股上市公司为研究样本,基于美国对华科技“脱钩”政策这一准自然实验衍生的外生冲击,运用双重差分模型探究美国对华科技“脱钩”政策对企业供应链韧性的影响,揭示美国对华科技“脱钩”政策对企业供应链韧性的作用机制。研究发现:(1)美国对华科技“脱钩”政策提升了企业供应链韧性,稳健性检验后该结论依然成立;(2)异质性分析结果表明,在非国有企业、东部区域和高科技产业,中国企业供应链韧性受美国对华科技“脱钩”政策的影响更显著;(3)美国对华科技“脱钩”政策通过提升供应链效率以及供应链集中度增强企业供应链韧性,而供应链合作复杂度则会抑制企业供应链韧性水平提升。研究结论有助于为推动中国企业供应链高质量发展提供经验证据和管理启示。
Led by the US,developed countries have modified supply policies towards China,seeking technological decoupling via a"de-Chinaized"supply chain.In response,China has introduced a“double-cycle”development strategy.Enterprises are the core forces to cope with changes in the trade pattern,and ensuring the resilience of enterprise supply chains and security is the top priority for realizing high-quality economic development.Currently,there are few studies in the academic community that utilize U.S.policy of technology decoupling from China as an empirical target to investigate the resilience of enterprise supply chains.This research gap could potentially hinder China's ability to manage the risks inherent in a volatile global market.Therefore,in the context of China's new round of opening-up policy,it is important to explore how U.S.policy of technology decoupling from China affects the resilience of enterprise supply chains,which provides a basis for how enterprises can enhance supply chain resilience in the complex international situation.This research is of great theoretical significance and practical value for the promotion of high-level opening to the outside world in line with the double-cycle development strategy.To explore the impact of U.S.policy of technology decoupling from China on the resilience of enterprise supply chains,this study utilizes a sample of A-share listed firms from the period 2010-2022 to investigate this impact.The starting time of the US-China technology decoupling policy is identified as 2018.The impact of the US-China tech-nology decoupling policy on the cooperation between enterprises and their upstream and downstream partners is significant.Specifically,customer sales(Y1)and supplier procurement(Y2)are considered as the dependent variables.The analysis yields some findings.First,the U.S.policy of technology decoupling from China significantly enhances the resilience of enterprise supply chains,and this finding remains reliable after the robustness test.Second,the heterogeneity analysis shows that the resilience of enterprise supply chains is more significantly positively affected by U.S.technology decoupling from China for the non-state-owned enterprises,eastern region,and high-tech industry categories.Third,further research has found that the U.S.policy of technology decoupling from China promotes corporate supplier procurement volumes by driving supply chain efficiency.Additionally,this policy enhances the resilience of enterprise supply chains by increasing supply chain concentration.However,the U.S.policy of technology decoupling from China also inhibits the improvement of resilience of enterprise supply chains through the complexity of supply chain collaborations.This article makes novel contributions to the research on enterprise supply chain resilience.Firstly,it offers fresh empirical evidence,a significant advancement since the current literature is heavily reliant on qualitative analyses and lacks empirical studies on the relationship between the U.S.policy of technology decoupling from China and supply chain resilience.By integrating both qualitative and quantitative analysis methods,this paper uncovers this relationship,thereby providing valuable empirical evidence for management science research on supply chain resilience.Secondly,it expands and enriches the theoretical research on U.S.policy of technology decoupling from China and resilience of enterprise supply chains.Most of the existing studies examine this issue from the macro level of industry and national strategy.In this paper,from the micro level of enterprises,we discuss how the enterprise supply chains can cope with the unfavorable impacts brought by the changes in the international situation,so as to enrich the theoretical content of the relevant research.Lastly,the paper provides actionable strategies to bolster the resilience of Chinese enterprise supply chains.Given the frequent occurrence of unforeseen events in science and technology policies and international relations,and the scarcity of studies on the influence mechanisms and operational frameworks behind these uncertainties,this paper elucidates the mechanism of U.S.policy of technology decoupling from China affecting the resilience of enterprise supply chains,and provides effective practical insights for enterprises to enhance the resilience of supply chain.
