Study on intercity differences of Chinese Urban economic Efficiency and Its Spatial - temporal characteristics: Base on 273 Cities at Prefecture level or above in China

摘要

This paper measures the urban economic efficiency using the three-stage DEA and analyzes the differences and temporal characteristics of the intercity, based on the data from 273 Cities at Prefecture level or above in China during the period 2002 - 2011. The results indicate that: (1) Urban economic efficiency three-stage DEA estimated was significantly lower than the general DEA, indicating that environmental and random factors have a great impact on urban economic efficiency in China; (2) China's urban economic efficiency intercity difference is very significant, "Bei-Shang-Guang" Metropolitan is a major frontier; (3) Urban economic efficiency intercity difference spatial pattern is very stable, spatial concentration areas of the high efficiency and the low in the study little changed.
