Abstract With the rapid development of urbanization in China, energy consumption is rising increasingly. Urban energy consumption accounts for the biggest proportion of total energy consumption. It is important to measure urban energy efficiency scientifically and accurately for reasonable energy policy making. From multiple channels, data are collected and carefully prepared. Then the perpetual inventory method is adopted to measure the urban capital stock. According to Zhou et al.(2012)'s definition of energy efficiency based on Shephard energy distance function, the inefficiency of capital and labor is decomposed from the total production function. Based on urban capital stock, SFA is applied to measure the total factor energy efficiency of China's 245 cities from 2001 to 2013. Then urban total factor energy efficiency is compared among four regions, northern cities and southern cities, and city scales. Results show that the average of urban energy efficiency is slightly higher than 0.6, the top 10 cities are mainly located in the eastern coastal region; the last 10 cities are mainly located in the western region. Urban energy efficiency among four regions, northern and southern cities, and five scales shows obvious differences. Overall, there is a great potentiality in energy-saving for China's cities in the future.
