摘　　要：富有韧性的创新生态系统可为高质量发展提供更大腾挪空间。因此,研究如何提升创新生态系统韧性具有重要现实意义。本文从演化视角出发考察群落结构变化对区域创新生态系统韧性的影响及作用机制。基于2010—2019年中国发明专利合作申请数据和地理信息数据,运用复杂网络建模方法与面板模型进行实证检验。研究表明:在面临知识源冲击风险时,中国各区域创新生态系统的韧性有差异化表现;群落演化与区域创新生态系统的韧性呈现倒U型关系,即随着群落内紧外松的结构特征深化,韧性先上升后下降;异质性分析结果显示创新水平高、知识喷泉型区域的群落结构对韧性的影响边际效应更强;机制分析结果显示知识多样性是影响群落演化与韧性关系的中介因素。基于上述结论,本文提出创新主体与政策制定者要重视保障群落边界开放性、增强区域技术多样性,避免区域创新生态系统脆弱化发展。A resilient innovation ecosystem can provide greater room for high-quality development. Therefore, it is of great significance to investigate how to improve the resilience of the regional innovation ecosystem. Based on the 2010-2019 Chinese co-application inventions and geographic information data, this study used the complex network methods and panel models to investigate how community dynamics affect the resilience of the regional innovation ecosystem. The results of this study showed that, under the impact of knowledge source risks, community evolution has an inverted U-shaped impact on the resilience of regional ecosystems. With the evolution of the community structure of “tight inside and loose outside”(close connection within the community and sparse connection between communities), the resilience of the regional ecosystem first increased and then decreased. It showed that when the “tight inside and loose outside” of communities increases from a low level to a moderate level, it is beneficial to reduce information transmission costs and transaction costs, increase social capital within the community, and thus have a positive impact on the resilience of the regional innovation ecosystem;but when the community structure dynamics is changed from a moderate level to a higher level, it will lead to “lock-in dilemma”, which will have a negative effect on the resilience of the regional innovation ecosystem. Therefore, the moderate level of community structure is more conducive to the improvement of the resilience of regional innovation ecosystems. Knowledge diversity positively mediates the relationship between community evolution and regional ecosystem resilience. The evolution of community structure further affects the resilience of regional ecosystems by directly affecting the knowledge diversity within the community. As the degree of “tight inside and loose outside” of the community increases, the knowledge diversity within the community will first increase and then decrease. We explain this ph
