城市群数字经济企业的空间分布特征

Spatial Distribution Characteristics of Digital Economy Enterprises in Urban Agglomerations

中国数字经济发展存在不平衡、不充分的问题,刻画数字经济企业的空间分布特征,探究影响数字经济空间格局的外部因素,有助于实现数字经济区域协调发展。文章根据国家级城市群的划分将样本进行分组,利用2000—2019年全国工商企业注册信息数据,使用泰尔指数、莫兰指数等指标,刻画了中国数字经济企业的分布特征。结果表明:(1)2000—2019年,中国新注册数字经济企业的数量和平均注册资本均有所提升,从增量和增速角度看,城市群城市均要高于非城市群城市。(2)数字经济企业的空间分布差异在总体上呈现下降趋势,城市群内的下降程度要大于城市群间的下降程度,是数字经济总体空间分布差异缩小的主要来源。(3)设立国家级城市群具有显著的政策效应,显著提高了城市群城市新注册数字经济企业的数量和注册资本,放大了中心城市对非中心城市的正向溢出效应。

The development of digital economy in China is unbalanced and inadequate.Describing the spatial distribution characteristics of digital economy enterprises and exploring the external factors affecting its spatial pattern are helpful to realize the regional coordinated development of digital economy.Based on the classification of national-level urban agglomerations and the registration data of industrial and commercial enterprises in China from 2000 to 2019,it analyzes the distribution features of digital economy enterprises in China by the means of the Theil index and Moran index.The main research findings are as follows:1) From 2000 to 2019,the number of newly registered digital economy enterprises and their average registered capital in China both exhibited an upward trend,it was higher in cities of urban agglomerations than that of other cities in terms of increment and growth.2) In general,the spatial distribution disparities of digital economy enterprises showed a downward trend,and the decline degree within urban agglomerations was greater than that between urban agglomerations,which is the main source of the reduction of the overall spatial distribution difference of digital economy.3) The establishment of national-level urban agglomerations exhibited significant policy effects,which significantly increased the number and registered capital of newly registered digital economy enterprises in urban agglomeration cities and amplified the positive spillover effects of central cities on non-central cities.
