精明发展与绿色经济效率的时空协调特征及影响因素OA

Smart development focuses on measuring the sustainable development degree of urban"connotative"growth.Green economic efficiency emphasizes protecting the environment while achieving economic growth.Taking smart development and green economic efficiency as the breakthrough point,based on the relevant index data from 2013 to 2022,this paper comprehensively uses entropy method,Super-SBM efficiency evaluation method and coupling coordination degree to analyze the smart development,green economic efficiency and coupling coordination performance of the three urban agglomerations,and uses Tobit model to explore the core factors affecting the coupling coordination degree.Research results show that:(1)From 2013 to 2022,the smart development level of the three major urban agglomerations showed a fluctuating upward trend,the smart development level of the Beijing-Tianjin-Hebei urban agglomerations is higher,and the level of the Yangtze River Delta is lower,but the growth rate is the fastest.(2)The fluctuation trend of green economic efficiency level of the three urban agglomerations is similar to the smart development level.From the perspective of green economic efficiency growth,Beijing-Tianjin-Hebei is higher than the Yangtze River Delta and the Pearl River Delta.(3)The coupling coordination level of green economic efficiency and urban smart development has a tendency to shift to a higher level over time,and the overall performance of the coordination of urban agglomeration in the Pearl River Delta is better than that in Beijing-Tianjin-Hebei and the Yangtze River Delta.(4)On the whole,the structural upgrading has a significant positive impact on the coupling coordination of the two systems.From the perspective of the performance of urban agglomerations,the level of science and technology and the level of government regulation have a significant positive impact in Beijing-Tianjin-Hebei and the Pearl River Delta,the level of energy consumption has a significant negative impact in the Yangtze River Delta,and the degree of dependence on foreign capital has a negative and positive effect in Beijing-Tianjin-Hebei and the Yangtze River Delta,respectively.Research results have important theoretical and practical significance for regional economic policy-making and local development.
