我国区域经济发展效率的时空变化及影响因素分析——基于超效率DEA模型的实证分析

The Empirical Analysis of the Time-Space Change and Influencing Factors about China's Regional Economic Development Efficiency:Based on the Super-Efficiency DEA Model

我国区域经济差异问题的研究很多,而有关区域经济发展效率特别是其影响因素的研究则较少。文章运用超效率DEA模型测度了我国29个省份(自治区、直辖市)1978-2007年度的区域经济发展效率,分析其时空变化趋势,对各地区的经济发展类型进行划分并提出实现效率的策略,最后通过构建计量模型分析了我国区域经济发展效率的四个影响因素。结果表明:我国区域经济发展效率呈倒U型变化趋势;省际间效率差异及东-西部与东-中-西部的地带间效率差异较大;四个因素对于全国及东中西三大区域的影响迥异,应根据各地区的实际情况提升发展效率,实现经济高效快速增长。

There are lots of researches on China＇s regional disparities, but few are on China＇s regional economic development efficiency, especially on its influencing factors. In this paper, the Super-Efficiency DEA model has been utilized to estimate economic development efficiency of 29 provinces （autonomous regions, municipalities） in China and analyze the time and space change tendency during 1978 -2007. Then, all these areas＇ economic development types are divided and the efficiency strategies are proposed. Finally , econometric models are constructed to analyze the four influencing factors of the regional economic development efficiency. The empirical results show that： China＇s regional economic development efficiency presents inverted U-trend; The differences in various areas＇ efficiency arc mainly for inter-province, east-west and east-middle-west regional efficiency variance; Four factors are different to the whole nation and the three big regions;it is necessary to improve regional economic development efficiency according to the individual difference and the actual situation; Economic growth way is necessarily transformed to achieve rapid and effective economic growth.
