Researsh On Local Cluster Relationship Under The Background Of Digital Economy

Along with the continuous progress of Internet information technology,digital economy has arrived.Industry digitalization and digital industrialization are important characteristics of future economic development.At present,our country is in a critical period of strategic adjustment of economic structure and transformation of economic development mode.Promoting the transformation from "Made in China" to "Made in China" with the help of Internet information technology is an important part of the strategic adjustment of economic structure.In addition,the digital economy also has an impact on the development mode of traditional industries.The new cluster model of "virtual industrial cluster" has appeared in the traditional industrial cluster,and this impact may also be reflected in the local cluster relationship.In this paper,the equipment manufacturing industry is taken as the research object,and the influence of the proximity of the Internet information industry cluster on the total factor productivity of the enterprises in the equipment manufacturing industry cluster is taken as the entry point,to study the traditional local cluster relationship under the digital economy.First,it reviewed the industry correlation theory and externality correlation theory,which laid the theoretical foundation for the subsequent study of cluster relationship.Then it sorted out the relevant literature of industrial cluster and the digital transformation of manufacturing industry.On the basis of summarizing and sorting out,it analyzed the research focus and research deficiencies of the existing theories,and led to the specific research content and research hypothesis of this paper.In terms of empirical methods,this paper mainly adopts propensity score matching method and differential method,and uses fixed effect model to regression data.The model uses enterprise panel data from 2010 to 2019.On the basis of basic regression,a series of robustness tests,heterogeneity tests and mechanism tests are combined to analyze the problems.This paper finds that:(1)Under the background of digitalization,the adjacent Internet information industry cluster has a significant positive impact on the total factor productivity of enterprises in the equipment manufacturing industry cluster,indicating that the local cluster relationship network is still important for industrial development under the background of digitalization.(2)The local cluster relationship between the Internet information industry cluster and equipment manufacturing industry cluster has different significance in different enterprise nature and enterprise scale.The influence of this relationship is more significant in private enterprises and large enterprises,but not in state-owned enterprises and small and micro enterprises.(3)Technological innovation and enterprise management efficiency are important intermediary mechanisms of cluster relationship under the background of digitalization.In view of the above conclusions,this paper puts forward corresponding policy suggestions.
