基于数据包络分析的珠三角城市竞争力研究

本文运用可变规模的数据包络分析,采用2005-2007年珠三角城市数据从资源利用效率的角度出发对珠江三角洲城市竞争力进行评价分析。数据包络分析结果显示,整体上珠三角城市竞争力较强,但城市平均效率出现缓慢下降趋势,规模效率下降大于纯技术效率下降。

A Study on Urban Competitiveness in Pearl River Delta Based on the Data Envelopment Analysis

Based on the urban data of Pearl River Delta from 2005 to 2007,this paper evaluates the urban competitiveness from the perspective of resources utilization efficiency by employing variables to scale data envelopment analysis.The urban competitiveness framework includes economic competitiveness,social competitiveness and environmental competitiveness.The results of data envelopment analysis show that the cities in Pearl River Delta have a relatively strong competitiveness on the whole.However,the average urban efficiency tends to decrease slightly and the scale efficiency has a more significant downward trend than technique efficiency.
