【摘要】 基于创新价值链，测度2011—2019年中国30个省份在科技研发和成果转化阶段的创新效率，以地方政府财政支出结构和效率为中介变量构建Tobit模型，实证检验财政分权对两阶段区域创新效率的影响机制。结果表明，财政分权在转化阶段对区域创新效率存在显著的抑制效应，在研发阶段的影响不显著。财政支出结构所起到的中介效应可在一定程度上掩盖财政分权对区域创新效率的抑制作用，并且在研发阶段的遮掩效应更大；而分权会降低财政支出效率，对双阶段区域创新效率产生抑制作用。更多还原

【Abstract】 Based on the innovation value chain, this paper measures the innovation efficiency of 30 provinces in China in the stage of scientific R&D and achievement transformation from 2011 to 2019, constructs Tobit model with the structure and efficiency of local government fiscal expenditure as intermediary variables, and empirically tests the impact mechanism of fiscal decentralization on the two-stage regional innovation efficiency. The results show that fiscal decentralization has a significant inhibitory effect on regional innovation efficiency in the transformation stage,and the impact is not significant in the R&D stage. The intermediary effect of fiscal expenditure structure can mask the inhibitory effect of fiscal decentralization on regional innovation efficiency to a certain extent, and the masking effect is greater in the R&D stage; Decentralization will reduce the efficiency of fiscal expenditure and inhibit the efficiency of two-stage regional innovation.更多还原
