摘要
本文重点关注互联网发展对制造业效率的影响这一现实问题。研究通过超边际与一般均衡分析,建立了互联网发展影响制造业效率的理论模型,揭示了互联网发展提升制造业效率的内在机制,并选取历史数据作为工具变量,在克服内生性的基础上,从城市、行业和企业三个维度全面检验了互联网发展对中国制造业效率的影响强度和内在机制。研究显示,互联网发展显著促进了城市整体和制造业整体生产率,且对制造业整体生产率的影响大于其对城市整体生产率的影响;互联网发展显著提高了制造业企业生产率。城市互联网发展指数每提高1%,制造业企业的生产率会提高0.3%。内在机制检验结果显示,互联网技术发展通过降低交易成本、减少资源错配以及促进创新提升了制造业生产率。以上研究结论为中国实施“互联网+”行动计划、建设网络强国和制造强国战略奠定了理论与事实基础。
This paper focuses on the practical problem of the impact of internet development on the efficiency of manufacturing industry. Through the analysis of the hyper marginal and general equilibrium, the study establishes a theoretical model of internet development that influences the efficiency of manufacturing, and reveals the internal mechanism of the development of the internet to enhance manufacturing efficiency.And this paper selectes the historical data as a tool variable, on the basis of overcoming the endogeneity, the impact strength and internal mechanism of the development of the internet on the efficiency of the manufacturing industry are fully examined from the three dimensions of the city, industry and enterprise. The research shows: internet development has significantly promoted the overall productivity of the whole city and the manufacturing industry, and the impact on the overall productivity of the manufacturing industry is greater than the overall productivity of the city. Internet development has significantly improved the productivity of manufacturing enterprises. With an increase of 1% in urban internet development index, the productivity of manufacturing enterprises will increase by 0.3%. The results of internal mechanism test show that internet technology development improves manufacturing productivity through reducing transaction costs, reducing resource mismatch and promoting innovation. The above conclusions laid a theoretical and practical foundation for China’s implementation of the“Internet +” action plan, the construction of a network power and the strategy of manufacturing power.
