智能制造是制造强国建设的主攻方向,智能制造试点是引领带动智能制造高质量发展的重要制度探索.本文基于2010-2021年中国A股制造业上市企业数据,以智能制造试点示范专项行动为准自然实验,利用多时点双重差分模型考察智能制造对中国企业创新的影响效应及其作用机制.研究发现,智能制造试点显著促进了企业创新,该结论通过多种稳健性检验依旧成立.机制分析表明,智能制造试点能够通过增加研发投入、提升人力资本水平、缓解融资约束推动企业创新.异质性分析表明,智能制造试点的创新驱动效应因企业、行业、地区特征的不同而呈现差异性,在大规模企业、高技术行业企业以及东部地区企业中更为显著.为此,应扩大智能制造试点示范范围,坚持外部融资获取增加与内部研发投入增加并举,坚持培养和引进人才"两条腿"走路,坚持因企施策、实施差异化发展路径,以更好地促进中国制造业企业智能化转型,推动制造强国战略实施.
Intelligent Manufacturing Pilots and Enterprises Innovation——A Quasi-Natural Experiment Based on the"Intelligent Manufacturing Pilot Demonstration Project"
Intelligent manufacturing is the main direction of the construction of a strong manufacturing country,and intelligent manufac-turing pilot is an important institutional exploration to lead and drive the high-quality development of intelligent manufacturing.Based on the data of A-share listed manufacturing enterprises from 2010 to 2021,this paper uses the quasi-natural experiment of an intelligent manufacturing pilot demonstration project to investigate the effect of the intelligent manufacturing strategy on enterprises innovation and the mechanisms by multiple-time-point difference-in-differences model.Results show that intelligent manufacturing pilots significantly promote enterprises innovation,which remains valid through a variety of robustness tests.The mechanism analysis shows that the intelli-gent manufacturing plots can promote enterprises innovation by increasing R&D investment,upgrading human capital and easing finan-cing constraints.Heterogeneity analyses show that the innovation-driven effects of intelligent manufacturing pilots are differentiated by the characteristics of enterprises,industries and regions,which are more significant for enterprises that are larger,in high-tech industries,and in eastern regions.In the end,it is necessary to expand the scope of pilot demonstration of intelligent manufacturing,adhere to the increase in external financing and internal R&D investment,and adhere to the"two-legged"approach of cultivating and introducing tal-ents,adhere to enterprise-specific policies and implementing differentiated development paths,to better promote the intelligent trans-formation of China's manufacturing enterprises and the implementation of the strategy of a strong manufacturing country.
