中国数字经济与制造业匹配发展及收敛性分析——基于全国30个省市经验数据

Matching Development and Convergence Analysis of China’s Digital Economy and Manufacturing Industry:Based on Empirical Data from 30 Provinces and Cities in China

数字经济作为中国经济的核心增长极,为实现中国制造向中国智造的转型升级做出了重要贡献。基于中国30个省市2014-2021年的相关统计数据,构建数字经济与制造业评价指标体系并运用熵值法对其进行综合评价,分析数字经济与制造业匹配发展区域差异原因,进一步运用σ收敛与β收敛模型分析两者匹配发展区域差异的演变趋势。研究结果表明:中国数字经济与制造业匹配发展区域差异较为明显,区域差异是造成总体差异的主要原因;分区域看,数字经济与制造业不存在σ收敛,但两者的绝对β收敛和条件β收敛显著。上述研究结果对把握中国数字经济与制造业匹配发展规律以及动态调整相关政策以促进经济高质量发展提供了理论依据。

The digital economy,as the core growth pole of China's economy,has made important contributions to the transformation and upgrading from Made in China to Made in China.Based on relevant statistical data from 30 provinces and cities in China from 2014 to 2021,a digital economy and manufacturing evaluation index system is constructed,and the entropy method is used to comprehensively evaluate it.The reasons of regional differences in the matching development of the digital economy and manufacturing industry are analyzed,and the evolution trend of regional differences in the matching development of the two is further analyzed using theσconvergence andβconvergence models.Research has shown that there are significant regional differences in the matching development of China's digital economy and manufacturing industry,and regional differences are the main reason for the overall differences;From a regional perspective,there is no sigma convergence between the digital economy and manufacturing industry,but their absolute beta convergence and conditional beta convergence are significant.The above research results provide a theoretical basis for grasping the matching development law between China's digital economy and manufacturing industry,as well as dynamically adjusting relevant policies to promote high-quality economic development.
