Digital economy is a new driving force for China's high-quality economic development.This paper focuses on the basic facts of the strengthening trend of enterprises'R&D cooperation,from the dual perspectives of innovation chain upgrading and supply chain optimization,and uses the matching data of China's prefecture-level cities and listed companies to investigate the effect and mechanism of digital economy development on enterprises'collaborative innovation. The results are as follows.(1)The digital economy has a significantly positive effect on collaborative innova-tion performance of enterprises,which is particularly significant in digital economy companies and state-owned en-terprises.(2)The mechanism test shows that the digital economy improves collaborative innovation performance of enterprises through two ways:one is to strengthen the breadth and depth of cross-organizational R&D collaboration to realize the upgrading of innovation chain;the other is to improve the concentration of customers and reduce the concentration of suppliers to realize the optimization of supply chain.(3)From the perspective of innovation chain,the expansion analysis results based on panel threshold regression show that there is a significant threshold effect be-tween the breadth and depth of R&D cooperation and collaborative innovation performance of enterprises,and the interaction between the two exists an optimal interval. This paper makes contributions in the following two aspects.(1)This paper,from the perspective of interac-tion between different enterprises,tries to analyze the inherent mechanism and impact of the development of the digital economy on the coordinated innovation of enterprises,so as to provide new evidence for related fields.(2)In terms of research content,on one hand,based on the existing theoretical basis,this paper further considers the multiple spillover effects of digital economy,such as technology diffusion and network externalities,and emphasize the mechanism of enabling enterprises to collaborate on innovation through innovation chain upgrading and supply chain optimization.On the other hand,the panel threshold model is used to investigate the nonlinear relationship between the breadth and depth of cross-organization R&D collaboration and enterprise collaborative innovation from the perspective of innovation chain,responding to the phenomenon of inconsistent research conclusions at present.At the same time,the conclusions of this article provide practical guidance for enterprises to effectively carry out R&D cooperation under the digital economy,and provide policy implications for the government to formulate appro-priate digital economy development strategy.
