Information Infrastructure Construction and Enterprise Intelligent Manufacturing:Evidence from the"Broadband China"Policy
Based on the matching data of prefecture-level cities and manufacturing listed companies from 2009 to 2021 of China,this paper analyzes how information infrastructure construction affects enterprise intelligent manufacturing by using the multi-period difference-in-differences method.The research finds that the"Broadband China"pilot can promote the development level of enterprise intelligent manufacturing in pilot cities.Mechanism analysis shows that information infrastructure construction promotes enterprise intelligent manufacturing through the dual path of technological innovation and cost reduction,and the improvement of marketization is conducive to leveraging the driving role of information infrastructure construction in enterprise intelligent manufacturing.Heterogeneity analysis shows that it is easier for information infrastructure construction to promote intelligent manufacturing in state-owned enterprises,high-tech enterprises and large-scale enterprises.Therefore,we should strengthen the construction of information infrastructure system,accelerate the pace of market-oriented reform,reduce technical barriers and cost burdens,and promote the transformation of enterprise intelligent manufacturing.
