Abstract: Based on the theories of resource dependence and behavior coordination, this paper analyzes the black box of improving cooperative performance mechanism. Collecting relevant data on the cooperative innovation of 339 high-tech enterprises in the Yangtze river delta region in 2018, and verifies the mechanism of resource complementarity and behavior synergy to improve the cooperative performance of high-tech enterprises by using the structural equation., capturing the effective Promoting path of to improve the cooperation performance of high-tech enterprises, found:（1） "Ability matching → behavior coordination → cooperative performance" is the key path to improve the cooperative performance of high-tech enterprises. (2) resource complementarity and behavior coordination have a significant positive impact on the cooperative innovation performance of high-tech enterprises. (3) subject characteristics have a significant positive impact on the cooperation process. (4) resource characteristics have a differentiated impact on the cooperation process. (5) government support has a significant positive impact on the cooperation process. (6) market environment has a significantly differentiated impact on the cooperation process. Based on this, the paper puts forward some Suggestions to improve the cooperation performance of high-tech enterprises in China effectively.

摘要： 基于资源依赖、行为协同等理论解析了提升合作绩效机制的黑箱；收集2018年长三角地区339个高新技术企业合作创新的相关数据，运用结构方程验证了资源互补与行为协同提升高新技术企业合作绩效的机制，找准提升高新技术企业合作绩效的有效路径。发现：(1)“能力匹配→行为协同→合作绩效” 是提升高新技术企业合作绩效的关键路径。（2）资源互补与行为协同对高新技术企业合作创新绩效具有显著正影响。(3)主体特征对合作过程具有显著正影响。(4)资源特性对合作过程有差异化影响。(5)政府支持对合作过程具有显著正影响。(6)市场环境对对合作过程有显著差异化影响。在此基础上，提出了提升我国高新技术企业合作绩效的针对性建议。
