中国沿海开放城市效率研究

Research on Efficiency about Coastal Open Cities in China

基于中国18个沿海开放城市2001-2013年的经济面板数据,本文运用DEA模型、超效率DEA模型以及DEA-Malmquist指数模型,测度各沿海城市静态效率和全要素生产率。结果显示:中国沿海开放城市综合效率较高,技术效率在综合效率变化中起主要作用,规模收益阶段与城市效率水平密切相关;Malmquist指数显示沿海开放城市动态全要素生产率年均增长为-0.8%,且动态效率经历了先抑后扬的变化趋势,技术进步是限制城市动态效率提升的主要原因。

By using DEA model, super efficiency DEA model and DEA-Malmquist index model with the data of 18 coastal open cities in China from 2001 to 2013, this essay measures the static efficiency and TFP of coastal open citiesl Results show that the comprehensive efficiency of coastal open cities in China is high, the technical efficiency plays a major role in the changes of comprehensive efficiency, and the stage of returns to scale is closely related to city efficiency level; the Malmquist Index shows the dynamic TFP of coastal open cities has been growing -0. 8% average annually, and the dynamic efficiency experiences a changing trend of declining prior to ascending, and technological progress is the main reason limiting the promotion of urban dynamic efficiency.
