Abstract: At present,the security and stability of the global manufacturing industry chain are facing unprecedented challenges.How to improve the resilience of the industry chain and strengthen the construction of the industry chain has become an urgent problem to be solved.Based on the balanced panel data of 30 provinces and cities in China from 2007 to 2017,from the perspective of industrial transformation and upgrading and innovation chain construction,this paper studies the impact of collaborative agglomeration of manufacturing industry and science and technology service industry (hereinafter referred to as collaborative agglomeration of two industries) on the resilience of manufacturing industry chain,and discusses how the collaborative agglomeration of two industries affects the resilience of manufacturing industry chain by influencing technological innovation,On this basis,we further explore the regulatory role of innovation ecosystem symbiosis in this mechanism.The research finds that: the collaborative agglomeration of two industries can significantly promote the resilience of the manufacturing industry chain by influencing technological innovation.The symbiosis of innovation ecosystem can effectively adjust the impact of the collaborative agglomeration of two industries on the resilience of the manufacturing industry chain.The collaborative agglomeration of two industries can not only directly affect the toughness of the manufacturing industry chain,but also effectively adjust the impact of technological innovation on the toughness of the manufacturing industry chain.Based on the above research conclusions,relevant suggestions are put forward to enhance the resilience of the manufacturing industry chain.

摘要： 当前，全球制造业产业链安全稳定面临前所未有的挑战，如何提升产业链韧性、加强产业链建设成为亟需解决的问题。基于2007-2017年中国30个省市的平衡面板数据，从产业转型升级和创新链构建等视角，研究制造业与科技服务业协同集聚（简称“两产业协同集聚”）对制造业产业链韧性的影响，探讨两产业协同集聚如何通过影响技术创新对制造业产业链韧性产生影响的作用机制，并在此基础上进一步探究创新生态系统共生性在此机制中的调节作用。研究发现：两产业协同集聚可通过影响技术创新对制造业产业链韧性产生显著的促进作用；创新生态系统共生性可有效调节两产业协同集聚对制造业产业链韧性的影响；两产业协同集聚不仅可以直接影响制造业产业链韧性，而且可以有效调节技术创新对制造业产业链韧性的影响。根据上述研究结论对增强制造业产业链韧性提出相关建议。
