【摘要】 基于中国30个省域2011—2019年规模以上工业企业面板数据，采用空间计量模型分析政府科技资助对企业研发投入的直接和空间溢出效应，并进一步探讨企业异质因素的调节作用。结果表明：政府科技资助除了对企业研发投入具有直接正向激励效应外，还具有空间溢出效应；企业规模、技术水平和盈利能力对企业研发投入具有正向影响，而产权性质对企业研发投入具有负向影响；企业规模与技术水平在政府科技资助与企业研发投入间的关系具有正向调节作用，而产权性质在两者间关系不具有显著的调节作用。更多还原

【Abstract】 Based on the panel data of industrial enterprises above designated size from 2011 to 2019 in 30 provinces of China, the direct and spatial spillover effects of government scientific and technological subsidies on enterprises R&D investment is empirically analyzed and the moderating effect of heterogeneous factors is further explored. The results show that government scientific and technological subsidies not only have direct positive incentive effect on enterprises R&D investment, but also have spatial spillover effect. Firm size, technology level and profitability have positive impact on firm R&D investment, while property rights have negative impact on firm R&D investment. Firm size and technology level have positive moderating effect on the relationship between government S&T subsidies and firm R&D investment, while property rights do not have significant moderating effect on the relationship between them.更多还原
