互联网化提升制造业全要素生产率的机制研究——基于中介效应与PSM-DID模型的研究

Research on the Improvement Mechanism of Internetization on Total Factor Productivity in Manufacturing Industry——An Analysis Based on Mediation Effects and PSM-DID Model

新发展阶段中国要以推动高质量发展为战略导向,以数字化转型变革生活、生产和治理方式是"十四五"规划中的一大战略。对国民经济支柱制造业而言,借助互联网化变革自身组织形态,拓展组织边界,实现全要素生产率的提升是关键。本文分析总结出制造业互联网化提升全要素生产率的3条机制即降低交易成本、提高资源利用效率和促进技术创新,并基于2010~2019年间制造业上市公司的数据,使用倾向得分匹配双重差分法对影响机制进行了验证。研究发现,制造业互联网化能够显著提升企业的全要素生产率,且可以通过提高资源利用效率和技术创新能力来提升全要素生产率。但互联网化在一定程度上会造成成本的增加,从而对全要素生产率的提升产生一定的抑制作用。

In the new development stage China has to promote high-quality development as a strategic direction,and trans⁃forming the way of life,production and governance with digital transformation is a major strategy in the 14th Five-Year Plan.For the manufacturing industry,the pillar of the national economy,it is key to transform its own organizational form and expand organi⁃zational boundaries with the help of internetization to realize the improvement of total factor productivity.The analysis of this paper summarizes three mechanisms for internet-enabled manufacturing industries to enhance total factor productivity,namely,reducing transaction costs,optimizing resource allocation and promoting technological innovation.And based on the data of listed manufac⁃turing companies during 2010~2019,the impact mechanisms are verified using propensity-score-matching double-difference meth⁃od.It is found that manufacturing internetization can significantly improve the total factor productivity of enterprises,and it can en⁃hance total factor productivity by improving resource allocation efficiency and technological innovation capability.However,to a certain extent,internetization can cause an increase in costs,which will have a certain inhibitory effect on the increase of total fac⁃tor productivity.
