产业互联网对浙江省制造业集聚程度影响的实证研究——基于浙江省2008—2017年面板数据

An empirical study on the influence of industrial Internet on manufacturing agglomeration in Zhejiang province——based on panel data of Zhejiang province from 2008 to 2017

摘要:

本文使用EG指数测算浙江省制造业分行业集聚程度,发现集聚产业集中在低端技术制造业和高端技术制造业。随后从信息基础设施建设、信息产业发展、信息技术创新科研三个维度,构建产业互联网测度指标体系,研究产业互联网对不同产业结构制造业集聚影响的差异。结果表明,产业互联网对低端技术制造业的集聚起到弱化作用,而对高端技术制造业的集聚起到促进作用。信息产业发展显著弱化低端技术制造业集聚,而促进高端技术制造业集聚；信息技术创新科研会促进高端制造业集聚。

Abstract:

In this paper, EG index is used to calculate the agglomeration degree of manufacturing industries in zhejiang province, and it is found that the agglomeration industries are concentrated in low-end technology manufacturing and high-end technology manufacturing.Then, from the three dimensions of information infrastructure construction, information industry development, and information technology innovation and scientific research, an industrial Internet measurement index system was established to study the differences in the impact of industrial Internet on manufacturing agglomeration of different industrial structures.The results show that the industrial Internet plays a weakening role in the agglomeration of low-end technology manufacturing industry, and a promoting role in the agglomeration of high-end technology manufacturing industry.The development of information industry significantly weakens the agglomeration of low-end technology manufacturing and promotes the agglomeration of high-end technology manufacturing.Information technology innovation and research will promote the concentration of high-end manufacturing.
