Measurement and Analysis of Urban Total Factor Energy Efficiency in China

The improvement of urban energy efficiency is great significance to reduce carbon emissions and achieve China’s goal peak in 2030. Taking 266 cities as the research objects, each city measured by Super-SBM model. Then decomposed Malmquist index. results show that: In 2006, number high-efficiency areas small high are mostly distributed northeast southeast coastal areas. There was a phenomenon low agglomeration. But 2017, increased significantly. Northeast China increased, Southeast decreased, Central showed agglomeration or relatively According decomposition efficiency, technological progress main driving force for decline technical inhibits various cities.
