Spatial and temporal differences and convergence of efficiency in the eastern coastal urban concentrated areas of China

72-83.
Urban efficiency is a very important measuring index in the evaluation of urban development, and eastern coastal region is the most densely distributed place of cities in China. So it has very important theoretical and practical significance to analyze this region's changes of urban efficiency and spatial-temporal differences, for improving and developing the efficiency of China's cities, as well as optimizing the urban space layout. Based on SBM-DEA model, this paper first analyzed the spatial differences of urban efficiency in the eastern coastal urban concentrated areas of China. Then it analyzed the dynamic variation in total factor productivity (TFP) of urban concentrated areas by using Malmquist index, and examined the convergence. The results show that: (1) the overall level of Urban efficiency is still low and there is a large room for improvement in all the 7 urban concentrated areas in eastern coastal China. There are only 5 cities are efficiency, including Beijing, Shanghai, Shenzhen, Guangzhou and Dongguan city. The efficiency of the Pearl River Delta urban concentrated area is the highest, the efficiency of Beijing-Tianjin-Hebei is ranking second, and the other is West Strait, North Bay, the Yangtze River Delta, Central-southern of Liaoning, Shandong peninsula urban concentrated area in turn. (2) The excess input and output shortage problem are in all the 7 urban concentrated areas in eastern coastal China, and there is quiet different in output shortage pattern. The productivity of capital and technology is lower than human and land elements. The total economic benefit and social public benefit have great room to improve in all the 7 urban concentrated areas. (3) From 2003 to 2014, the TFP of urban efficiency shows a trend of rising in urban concentrated areas in eastern coastal China, and the technological progress has contributed more than efficiency progress to the TFP of urban efficiency. In particular, North Bay urban concentrated area should attache importance to the improvement of production technology. (4) Central-southern of Liaoning, the Yangtze River Delta, West Strait and North Bay urban concentrated areas have the club-convergence. In addition to Beijing-Tianjin-Hebei and the Pearl River Delta, the difference of TFP in other urban concentrated areas will gradually disappear automatically.
