资本深化与制造业部门劳动生产率的提升——基于工资上涨及政府投资的视角

Capital Deepening and Manufacturing Labor Productivity Growth:A Perspective Based on Wage Growth and Government Investment

资本深化是中国制造业劳动生产率提升的重要影响因素,本文从工资上涨及政府投资等角度分析转型期的资本深化,并进一步分析不同力量引致的资本深化对制造业劳动生产率的影响。借助不同时间段制造业行业面板数据的对比分析得出,政府投资主导的资本深化的作用显著大于工资上涨的作用,随着中国工资水平的提高,工资上涨引致的资本深化对劳动生产率的影响开始发挥作用,而政府投资引致的资本深化对劳动生产率的作用显著但呈下降趋势。此外,技术进步及行业规模报酬递增效应整体上显著促进了劳动生产率的提高,但各行业之间存在显著差异。

A Capital deepening plays an important part in China＇ s manufacturing labor productivity growth. This paper analyzes China＇ s capital deepening from the perspective of wage growth and government investment during the transitional period, and further analyzes their influences on manufacturing labor productivity growth. Using manufacturing industry panel data at different times, we conclude that the effect of government - led capital deepening is significantly greater than wage growth. With the increase of wage growth, capital deepening caused by wage growth begins to stimulate labor productivity growth, while government - led capital deepening begins to decline. In addition, technical progress and industrial scale significantly improve the labor productivity on the whole, but differently among industries.
