数字经济对包容性绿色增长差距的影响研究——基于关系数据分析范式

Research on the Impact of Digital Economy on Inclusive Green Growth Gap:Based on the Relational Data Analysis Paradigm

包容性绿色增长是促进共同富裕的重要手段。本文在数据包络分析框架下,将城乡收入差距和环境污染纳入包容性绿色TFP的测度中,利用QAP方法考察数字经济对包容性绿色增长地区差距的影响。研究发现:样本考察期,数字经济的均衡发展显著缩小包容性绿色增长的地区差距;其中,数字产业发展及数字技术创新对包容性绿色增长的地区差距具有显著的正向影响,而数字基础设施对包容性绿色增长的地区差距具有显著的负向影响。异质性分析发现:东部地区及南方地区数字经济的均衡发展显著缩小包容性绿色增长的地区差距;以城市群划分,优化提升类及发展壮大类城市群的数字经济均衡发展对包容性绿色增长地区差距缩小具有显著的促进作用;以城市经济水平划分,四线城市数字经济的均衡发展显著缩小了包容性绿色增长的地区差距。上述研究,对于“十四五”时期推动数字经济区域协调,缩小包容性绿色增长的地区差距以及共同富裕的实现具有重要的启示意义。

Inclusive green growth is an important means to promote common prosperity.This paper incorporates the urban-rural income gap and environmental pollution into the measure of inclusive green total factor productivity(TFP)under the data envelopment analysis framework,and utilizes the QAP method to examine the impact of the digital economy on the regional disparity of inclusive green growth.The study finds that the balanced development of the digital economy significantly reduces the regional disparity of inclusive green growth in the sample period.Among them,digital industry development and digital technology innovation have a significant positive impact on the regional disparity of inclusive green growth,while digital infrastructure construction has a significant negative effect on that.Heterogeneity analysis finds that the balanced development of the digital economy in the eastern region and the southern region significantly reduces the regional disparity of inclusive green growth.Under the division of city clusters,the balanced development of the digital economy in the optimization and enhancement category and the development and expansion category of city clusters significantly contribute to the reduction of the regional disparity of inclusive green growth.Under the division of the city's economic level,the balanced development of the digital economy in the fourth-tier cities significantly reduces the regional disparity of inclusive green growth.The above research conclusions have important implications for the promotion of regional coordination of the digital economy,the narrowing of regional disparity in inclusive green growth,and the realization of common prosperity during the 14th Five-Year Plan period.
