摘要
在分析R&D促进劳动生产率收敛的机理上,运用1999~2017年中国工业分省份分行业数据,分析R&D对工业劳动生产率收敛影响的特征事实,并采用双向固定效应模型考察R&D投入对工业整体、不同技术类型和不同产权性质下劳动生产率收敛的影响。结果显示,R&D投入会促进中国工业劳动生产率的收敛,但是存在行业异质性。对高技术行业的收敛驱动作用显著,而对中低技术行业的收敛存在抑制作用;对国有产权较低行业劳动生产率收敛的积极影响要高于国有产权较高行业。政府需要强化技术创新驱动政策,发挥科技创新驱动在全面创新驱动中的引领作用,推动混合所有制改革,关注不同行业特征来考虑R&D的投入效率和分配机制等因素。
This paper analyzes the characteristics of the impact of R&D on the convergence of industrial labor productivity by using the data of provinces and industries in China from 1999 to 2017,and uses the two-way fixed effect model to investigate the influence of R&D input on the convergence of labor productivity under the conditions of industry as a whole,different technology types and different property rights.Results show that R&D investment can significantly promote the convergence of China's industrial labor productivity and significantly improve the convergence of high-tech industries,but inhibit the convergence of low-tech industries.At the same time,the positive impact on labor productivity convergence of industries with lower state-owned property rights is higher than that of industries with higher state-owned property rights.The government needs to strengthen the technological innovation policy to improve the industrial convergence speed,an d pays attention to the characteristics of different industries to consider the R&D input efficiency and allocation mechanism.
