制造业投入服务化的生产率效应分析

The Productivity Effect of Servitization of Input in Manufacturing

基于要素投入视角,使用投入产出表数据,计算了中国28个制造行业的投入服务化水平,并运用面板数据模型实证检验了投入服务化对制造业生产率的影响,以及投入服务化对生产率影响的行业差异。研究结果表明:中国制造业投入服务化总体水平不高,并有下降趋势;投入服务化有利于制造行业生产率的提高,但作用不明显;投入服务化在劳动密集型行业的生产率效应大于资本密集型行业,在高技术行业和低技术行业的差异不明显。

From the perspective of inputs,the paper calculates the servitization level in China＇s manufacturing based on input-output data, and tests its effect on manufacturing＇s productivity and industrial disparity by a panel data model. The results show that the overall level of service input in manufacturing is low, and there is a tendency of decline. The influence of input servitization on manufacturing is positive but limited. The effect on productivity in the labor-intensive industries is larger than that of capital-intensive industries, while in the high-tech and the low-tech industries,the disparity is not obvious.
