珠三角城市群土地利用效率评价研究

Research on Land Use Efficiency in the Pearl River Delta City Group

为促进粤港澳大湾区的发展,本研究根据投入、产出两方面构建珠三角城市群土地利用效率评价指标体系,利用Malmquist面板指数和DEA-BC2模型确定评价模型,分别对珠三角城市群2009—2016年土地利用效率动态变化和2015、2016年各城市静态土地利用效率进行分析。结果表明,整个珠三角地区土地利用水平相对高效,土地利用效率总体呈上升趋势,但仅有广州、深圳的均值大于1;惠州连续两年综合技术效率均为非DEA有效,且规模收益递减,江门在2015年也出现此类情况,其余各城市均达到DEA有效。

In order to promote the development of Guangdong-HongKong-Macao Greater Bay Area, this study is based on the input and output two aspects to build up the evaluation index system of land use efficiency in the pearl river delta city group,and thc evaluation model is determined by using Malmquist panel index and DEA-BC2 model to analyze the dynamic change of land use efficiency in the pearl river delta city group from 2009 to 2016 as well as the static land use efficiency of cities in 2015 and 2016. The results show that the land use level in the pearl river delta region is relatively efficient and the land use efficiency is generally increasing, but only Guangzhou and Shenzhen have a mean value greater than 1. The overall technical efficiency of Huizhou for two consecutive years is not only non-DEA efficient, but also decreases in scale revenue.Jiangmen also appeared this kind of situation in 2015, and the rest of the cities reached DEA efficient.
