基于DEA模型和Malmquist指数的广东省城市效率分析

The City Efficiency Analysis of Guangdong Province——Based on the DEA and Malmquist Index Model

运用DEA模型对2013年广东省21个地级以上城市的技术效率及投入产出情况进行静态分析,发现其技术效率整体较低,且大部分城市存在投入过多的情况。运用Malmquist指数动态分析广东省21个地级以上城市在2004—2013年间生产率增长、效率改进与技术进步的变化情况,发现城市平均Malmquist生产率呈上升趋势,且技术水平的进步是推动城市平均生产率提高的主要因素;粤东和粤北城市的生产率增长速度开始快于珠三角城市,表明广东省的区域发展差距在逐渐缩小;珠三角地区城市的生产率提高主要来源于技术水平的进步,而粤东、粤西和粤北城市的生产率提高则主要来源于技术效率的改进。

The paper makes a static evaluation on the technical efficiency and the input-output situation of the 21 cities in Guangdong Province in2013 by using DEA model,it also carries out a dynamic analysis on the changes of productivity growth,technical efficiency improvement and technological progress of these cities from 2004 to 2013 by using Malmquist index.It finds that the overall technical efficiency of these cities is lower,and most of these cities have invested too much in 2013.In addition,the research finds that average Malmquist productivity of these cities has been improved from 2004 to2013,mainly contributed by technological progress.Productivity growth speed in the eastern and northern cities of Guangdong Province is faster than the Pearl River Delta cities,it shows that the regional development gap in Guangdong province is gradually narrowing.Productivity growth in Pearl River Delta cities comes mainly from the technical progress,however the productivity growth in the eastern,Western and northern cities of Guangdong Province comes mainly from technical efficiency improvement.These conclusions provide a policy path direction for the innovation driven strategy implementation of the new urbanization construction in Guangdong Province.
