摘　　要：基于2002-2021年中国30个省份的面板数据,探讨研发投入对产业结构升级的作用机制。实证分析结果表明,增加研发投入对产业结构的优化与升级具有显著的促进作用。进一步的中介效应检验揭示,研发资金的增长能够通过加快科技创新速度和提高居民收入水平两个途径,有效推动产业结构的优化与升级。特别是在西部地区,研发投入对产业结构升级的促进作用相较于中部和东部地区更为显著。鉴于实证分析结果,提出应通过加大科研投入力度、提高科技成果转化效率、根据区域经济特征制定差异化创新政策等政策建议推动产业结构升级,以期助推我国经济高质量发展。This article is based on panel data from 30 provinces in China from 2002 to 2021,to explore the mechanism of R&D investment on industrial structure upgrading.The empirical analysis results indicate that increasing R&D investment has a significant promoting effect on the optimization and upgrading of industrial structure.Further mediation effect testing reveals that the growth of R&D funds can effectively promote the optimization and upgrading of industrial structure through two channels:accelerating the speed of technological innovation and improving residents’income levels.Especially in the western region,the promotion effect of R&D investment on industrial structure upgrading is more significant than in the central and eastern regions.In view of the above empirical research results,it is proposed to promote the upgrading of industrial structure by increasing scientific research investment,improving the efficiency of scientific and technological achievements transformation,and formulating differentiated innovation policies based on regional economic characteristics,in order to promote the high-quality development of China’s economy.
