互联网对制造业劳动生产率的影响研究

Research on the influence of Internet on manufacturing labor productivity

研究旨在考察我国不断发展的互联网对制造业劳动生产率提升是否存在驱动作用。以我国2005-2013年城市面板数据为研究样本,实证分析互联网对制造业劳动生产率的影响。研究结果表明:互联网正向促进制造业劳动生产率提升,且该结果在经过稳健性检验后依然成立,同时金融危机后互联网的驱动作用比金融危机前更强。进一步的机制分析结果表明,互联网会通过降低生产成本和提高创新能力促进劳动生产率水平提高,但在样本期内,生产成本这一作用路径显著,创新能力这一作用路径不显著,且创新能力与劳动生产率之间呈"U"型关系。门槛分析发现互联网水平对制造业劳动生产率的影响存在双重门槛效应。最后,在研究结论的基础上得出一些政策启示:一是积极推动新一代移动通信网络基础设施建设;二是加快搭建工业互联网平台。

The study aims to test whether China’s evolving Internet is driving the increase in manufacturing labor productivity.Taking the panel data of China’s cities from 2005 to 2013 as a research sample,this paper empirically analyzes the impact of the Internet on labor productivity in manufacturing.The research results show that the Internet has promoted the improvement of labor productivity in the manufacturing industry.After the test of robustness,the results are still valid.At the same time,the Internet’s driving role after the financial crisis is stronger than before the financial crisis.Further analysis of this mechanism shows that the Internet will promote labor productivity by reducing production costs and improving innovation capabilities.However,in the sample period,the role of production costs is significant,while the role of innovation capabilities is not significant,and there is a"U"relationship between innovation capability and labor productivity.Threshold analysis finds that the impact of Internet levels on manufacturing labor productivity has a double threshold effect.Finally,on the basis of the research conclusions,some policy implications are proposed:First,actively promoting the construction of a new generation of mobile communication network infrastructure;second,accelerating the construction of industrial Internet platforms.
