智能化对中国制造业全要素生产率的影响研究

Research on the influence of intelligentization on total factor productivity of China’s manufacturing industry

基于2003-2015年中国省级面板数据,使用DEA-Malmquist模型测算了中国制造业全要素生产率的变动,并实证检验了智能化对全要素生产率的影响。Malmquist测算结果表明:中国制造业全要素生产率在研究期内年均增长8.2%,且技术进步贡献了主要的全要素生产率的增长;制造业全要素生产率的增长存在明显的区域异质性,西部地区增长最快,其次是东部地区和中部地区。实证结果表明:智能化显著促进了全要素生产率的增长,且智能化是通过促进技术进步增长的方式实现对全要素生产率的促进作用,智能化对制造业技术效率没有明显的促进作用;智能化显著促进了中西部地区制造业全要素生产率的增长,且对西部地区促进作用更大,但对东部地区没有显著的促进作用。

Based on the 2003-2015 Chinese provincial panel data, this paper uses the DEA-Malmquist model to measure the change of total factor productivity in China’s manufacturing industry, and empirically tests the impact of intelligentization on total factor productivity and its mechanism. Malmquist calculation results show that the total factor productivity of China’s manufacturing industry is growing at an average annual rate of 8.2% during the study period, and the growth is mainly contributed by technological progress;the growth of total factor productivity in manufacturing exists obvious regional heterogeneity, the western region has the fastest growth, followed by the eastern and central regions. The empirical results show that: intelligentization significantly promotes the growth of total factor productivity, and intelligentization promotes total factor productivity by promoting the growth of technological progress. Intelligentization has no obvious promotion effect on the technical efficiency of manufacturing;intelligentization has significantly promoted the growth of total factor productivity in the central and western regions, and it has a greater role in promoting total factor productivity in the western region, but not in the eastern region.
