数字经济与黄河流域绿色经济效率:机制分析与实证检验
Digital Economy and Green Economy Efficiency in Yellow River Basin:Mechanism Analysis and Empirical Test
摘要
Abstract
The vigorous development of digital economy has provided a strong impetus for the transformation of economic growth mode,ecological protection and high-quality development in the Yellow River Basin.Based on the data of 62 cities in the Yellow River Basin from 2011 to 2020,this paper uses the principal component analysis method and the SBM model of unexpect-ed output to measure the development level of digital economy and the efficiency of green economy in each city,and then uses the panel fixed effect and intermediary effect models to empirically test the impact of digital economy on the efficiency of green econo-my in the Yellow River Basin and its mechanism.The research findings are shown as follows:First,digital economy can signifi-cantly improve the efficiency of green economy in the Yellow River Basin,and this conclusion is still valid after a series of robust-ness tests and endogenous treatments.Second,the mechanism test shows that digital economy can empower the green transforma-tion and development of the Yellow River Basin by boosting the upgrading of industrial structure and promoting green technology innovation.Third,the heterogeneity analysis shows that the impact of digital economy on the efficiency of green economy in the Yellow River Basin is different due to different geographical locations,administrative levels and resource endowments of cities.关键词
