摘　　要：数字经济对驱动产业体系重构、范式迁移,建设统一大市场具有重要意义。基于异质性企业模型,构建了数字经济下封闭经济体内省际(省份间)销售模型,探究了数字经济发展带来的生产成本变化与地区性行政垄断程度变化及其对产业过度同构化的影响,并对该影响的空间溢出效应进行了分析。利用测算所得的2011—2020年29个省份的产业同构化程度和数字经济发展程度数据对理论假设进行了实证检验。研究发现:数字经济发展能够有效降低产业过度同构化问题,在东部地区、数字经济创新水平较高以及市场化程度较低的地区数字经济发展对降低产业同构化的作用更加显著;相邻地区数字经济发展能够降低本地区产业同构化程度;数字经济发展能够通过降低生产成本和地区性行政垄断程度进而降低产业同构化程度。The digital economy is of great significance in driving the restructuring of industrial systems andthe shifting paradigms,as well as building a unified market.Based on a heterogeneous enterprise model,this paper constructs an inter provincial sales model within a closed economy under the digital economy to explore the changes in production costs and the changes of the degree of regional administrative monopolies brought about by the development of the digital economy,as well as their impact on the excessive industrial homogenization.The spatial spillover effects of this impact is also analyzed.The theoretical hypothesis is empirically tested by using the measured data of the degree of industrial homogenization and the degree of digital economy development in 29 provinces from 2011 to 2020.The findings show that the development of the digital economy can effectively reduce the problem of excessive industrial homogenization.In the eastern region,the areas with higher levels of digital economy innovation and lower levels of marketization,the role of digital economy development in reducing industrial homogenization is more significant.The development of digital economy in the adjacent areas can reduce the degree of industrial homogenization in the local area.The development of the digital economy can reduce the degree of industrial homogenization by reducing production costs and the degree of regional administrative monopolies.
