Study on the Spatial Differentiation of Total Factor Energy Efficiency of the"Belt and Road"Node Cities in China
The total factor energy efficiency of 17 cities along the Belt and Road from 2005 to 2019 is calculated by using SUPER-SBM-DEA models with unintended outputs,and the comparative anilysis is carried out from two dimensions of time and space,the influencing factors are explored with the help of Tobit model.Results display that the total factor energy efficiency of 17 cities is inefficient.The total factor energy efficiency between cities is varied and imbalanced.The total factor energy efficiency of the"Road"cities is always higher than that of the"Belt"cities.The Malmquist index of all cities along the Belt and Road is greater than 1.The contribution of technologi-cal progress to the growth of energy efficiency of the"Belt"node cities is more significant than that of the"Road"node cities.The tech-nological efficiencies of the"Road"node cities are quite different.The proportion of production factors,the opening degree,the research and development of technology and the price of energy have positive effects on the total factor energy efficiency,while the economic devel-opment and the industrial pollution have negative effects.The level of economic development has a significant positive impact on the ener-gy efficiency of the"Belt"node cities,while the proportion of production elements and energy consumption structure repress its develop-ment.Conversely,these three factors have negative impacts on the energy efficiency of the"Road"node cities.
