全要素生产率分解下的我国制造业异质性与成长能力研究

Research on the Heterogeneity and Growth Capability of Manufacturing Industry in China Based on TFP Decomposition

利用2003—2016年我国制造业28个分行业的面板数据,通过建立超越对数生产函数时变技术效率随机前沿模型,测算了我国制造业各分行业的全要素生产率(TFP)及其分解,并分析了各分行业TFP发展存在的异质性及其对成长能力的影响作用。结果表明,我国制造业各分行业在技术效率、技术进步、技术效率改进、规模效率改进、配置效率改进以及TFP指数方面表现出很大的差异性,制造业异质性对成长能力具有显著的正向促进作用。

By using the panel data of 28 industries of manufacturing industries in our country from 2003 to 2016 and using a translog production function to change the technical efficiency stochastic frontier model,this paper estimates total factor productivity(TFP)and its decomposition of manufacturing industries,and analysis TFP growth in the presence of heterogeneity of manufacturing industries and the impact of industrial heterogeneity on growth capability.The results indicate that China’s manufacturing industries show a great difference in technical efficiency,technical progress and technical efficiency improvement,scale efficiency improvement,improvement of allocation efficiency and TFP index.At the same time,industrial heterogeneity has a significant positive role in promoting its growth capability for manufacturing industries.This indicates that enhancing industrial heterogeneity is benefit to promote growth capability of manufacturing industries in China by promoting technical progress efficiency,transformating increasing manner and improving the total factor productivity.
