数字经济发展对黄河流域能源效率的影响
Impact of Digital Economy Development on Energy Efficiency in the Yellow River Basin
摘要
Abstract
In order to explore the impact of digital economic development on energy efficiency in the Yellow River Basin and its internal influ-ence mechanism,based on the panel data of 80 prefecture-level cities in the Yellow River Basin from 2011 to 2021,the three-stage DEA method was used to measure energy efficiency,and the entropy method was adopted to measure the development level of the digital economy.Taking the development level of the digital economy as the explanatory variable and energy efficiency as the explained variable,taking the level of financial development,the size of urban population,government fiscal expenditure,the level of science and technology expenditure,and the level of urbanization as control variables,the level of technological innovation,the level of industrial structure upgrading,and the in-tensity of environmental regulation as mediating variables,and the level of economic development as moderating variables,an individual fixed effect model was built to empiratically test the impact of digital economic development on energy efficiency.And the mediating effect,modera-ting effect and heterogeneity analyses were conducted.The results indicate that a)the development of the digital economy has a U-shaped im-pact on the improvement of energy efficiency in the Yellow River Basin,with an initial inhibitory effect followed by a promotional effect.Cur-rently,the level of digital economy development in the Yellow River Basin still inhibits the enhancement of energy efficiency.b)Technologi-cal innovation,industrial structure upgrading,and environmental regulation partially mediate the impact of the digital economy on energy effi-ciency.c)The level of economic development negatively moderates the U-shaped relationship between digital economy development and ener-gy efficiency,meaning that the impact of digital economy development on energy efficiency diminishes as the level of economic development increases.d)The impact of digital economy development on energy efficiency exhibits regional heterogeneity and heterogeneity in economic development levels.Currently,more cities in upstream areas experience improved energy efficiency due to digital economy development,fol-lowed by midstream areas,with downstream areas showing the least.The U-shaped impact of digital economy development on energy efficien-cy is more pronounced in relatively economically underdeveloped areas compared to relatively developed areas.At the end of the paper,the relevant countermeasures and suggestions are put forward.关键词
