摘　　要：文章深入探讨了数字政府建设对区域创新影响的内在机理,以是否建立省级一体化网上政务服务平台为“准自然实验”,采用双重差分方法和三重差分方法识别了数字政府建设对区域创新水平的净效应及其异质性。研究发现:数字政府建设政策显著促进了区域创新水平提高,包括对区域创新投入和产出水平均有显著正向效应,并且这一结论经过PSM-DID方法等一系列稳健性检验后仍成立;数字政府建设对提升区域创新水平的效应有显著的时间动态性和空间异质性,表现为政策效应大小呈逐年递增趋势,以及对南方地区相比北方地区、对制度环境较好或创新水平较高的地区相比其他地区的政策效应更佳;数字政府建设提升区域创新水平的作用机制在于降低制度性交易成本和优化法治化环境两个方面,其中降低制度性交易成本是最重要的机制。This paper makes an in-depth discussion on the internal mechanism of the impact of digital government construction on regional innovation,and by taking whether to establish provincial integrated online government affairs service platform as a“quasi-natural experiment”,uses the DID method and DDD method to identify the net effect and heterogeneity effect of digital government construction on regional innovation level.The results go as below:The digital government construction policy significantly promotes the improvement of the regional innovation level,including the significant positive effects on regional innovation input and output levels,and this conclusion still holds after a series of robustness tests such as the PSM-DID method.The effect of digital government construction on the improvement of regional innovation level has significant temporal dynamics and spatial heterogeneity,which is manifested as the policy effect increasing year by year,and the policy effect is better in the southern region than in the northern region,and the region with better institutional environment or higher innovation level than in other regions.The mechanism of digital government construction to improve regional innovation levels lies in reducing institutional transaction costs,optimizing the legal environment,accelerating informational construction and promoting the flow of innovation factors,among which reducing institutional transaction costs is the most important mechanism.
