空间效应视角下政府研发补贴对工业企业创新的影响研究OACHSSCD

From the perspective of spatial effects and based on panel data across China's provincial regions,this paper con-structs a Dynamic Spatial Durbin Model to empirically analyze the impact of government R&D subsidies on industrial enterprise inno-vation.The results indicate that that enterprise innovation inputs exhibit both temporal and spatial dependence.Temporally,inno-vation inputs from previous periods exert a significant driving effect on current inputs.Spatially,innovation inputs in neighboring re-gions initially stimulate local innovation.However,over time,a spatial crowding-out effect becomes evident.In contrast,enter-prise innovation output demonstrates dependence only in the temporal dimension.The impact of government R&D subsidies varies across different types of enterprise innovation inputs and outputs.Specifically,these subsidies exert a certain crowding-out effect on R&D expenditure while significantly promoting R&D personnel investment.Furthermore,the subsidies show a positive spatial effect on R&D personnel investment,verifying the existence of interregional competition in government R&D subsidy policies.Government R&D subsidies exert a positive effect on firms'patent output,thereby enhancing their overall level of innovative output.However,they do not show a significant effect on innovation quality and fail to effectively stimulate firms'incentives to engage in high-level in-novation.
