中国数字经济产出效率的动态测度及区域差异分析

Analysis on the Dynamic Measurement and Regional Differences of Output Efficiency for China’s Digital Economy

选取2010~2019年中国29个省份数字经济相关数据为研究样本,利用DEA-MI动态指数模型与Dagum基尼系数对各省份数字经济产出效率进行统计测度。结果表明:中国数字经济产出效率Malmquist指数整体表现出先升后降趋势;29个省份数字经济产出效率Malmquist指数存在显著空间异质性。进一步研究发现:七大区域数字经济产出效率差异存在不同程度变化态势,且区域间差异是导致中国数字经济产出效率存在地区差距的主要因素。鉴于此,应打造“政府+市场”双管齐下的共治模式,发挥社会非营利组织与市场组织等的作用,协调好经济与社会间的关系,从而实现数字经济产出效率提升。

This paper selects the data related to the digital economy of 29 provinces in China from 2010 to 2019 as the research sample,and uses the DEA-MI dynamic index model and the Dagum Gini coefficient to statistically measure the output efficiency of the digital economy in each province.The results show that the Malmquist index of China’s digital economy output efficiency shows an overall trend of rising first and then falling.There is significant spatial heterogeneity in the Malmquist index of digital economy output efficiency in 29 provinces.Further research shows that there are varying degrees of changes in the output efficiency differences of digital economy in the seven regions,and the regional differences are the main factors leading to the regional differences in the output efficiency of digital economy in China.In view of this,it is necessary to strengthen the“government+market”co-governance model,give play to other social non-profit organizations and market ones,and coordinate the relationship between economy and society,so as to achieve a reasonable improvement in the output efficiency of digital economy.
