摘　　要：数字赋能千行百业高质量发展,数字经济已成为中国全面建设社会主义现代化国家的重要引擎。基于2011—2020年中国省级面板数据,构建固定效应、中介效应和调节效应模型,从区域层面研究数字经济发展提升创新效率的影响机制。研究发现:当创新效率为被解释变量时,数字经济发展水平的回归系数显著为正,但东部、中部和西部地区的数字经济发展对创新效率的作用效果存在差异;对外贸易具有良好的中介效应,数字经济发展可以有效推动中国对外贸易来提升创新效率;市场竞争具有良好的调节效应,说明市场竞争程度越低的区域,数字经济发展对其创新效率的作用程度越高。Scientific and technological innovation is conducive to improving the efficiency of factor allocation and resource utilization,and is the driving force for China to continuously enhance its core competitiveness in the international arena.As of 2023,China's global innovation index ranking has risen from 34th place in 2012 to 12th place.However,compared with developed countries in the world,China's innovation level still needs to be further improved.According to the theory of innovation economics,technological revolutions usually give birth to new production factors.The data factor is the product of the digital technology revolution,which can create synergies with other production factors and drive the industry to achieve disruptive innovation.In order to effectively improve the quality of innovation and help build an innovative power,this paper collects Chinese provincial panel data from 2011 to 2020 to study the mechanism of digital economy development to improve innovation efficiency at the regional level.Firstly,this paper uses entropy method and stochastic frontier analysis method to calculate the digital economy development index and regional innovation efficiency of each province respectively.Secondly,a fixed-effect model is constructed to empirically test whether digital economy development can improve regional innovation efficiency by fixing provinces and years at the same time.In response to this conclusion,robustness tests,endogeneity tests,and heterogeneity tests will be conducted sequentially.Once again,this article constructs a mediating effect model based on stepwise regression methods to empirically test whether the development of digital economy can promote China's foreign trade,and subsequently enhance regional innovation efficiency.Finally,a moderating effect model is established to empirically examine how the degree of market competition moderates the effect of digital economy development on regional innovation efficiency.The research findings are as follows:The development of digital economy ca
