本文基于产出CCR模型,运用DEA方法对泛珠三角大陆地区的9个省份限额以上零售业2012年至2014年三年间的经营效率进行了测算和比较分析。分析结果表明,泛珠三角地区零售业经营效率存在东中西部省份差别,具有明显的梯度差异,东部地区在综合效率、纯技术效率和规模效率方面均高于中西部省份;达到DEA有效的只有江西、四川和云南3个省份;东部地区的广东省零售业进入规模报酬递减阶段,2014年的江西和云南、2013年的四川处于规模报酬不变,其他省份在三年间均处于规模报酬递增;东部省份投入冗余情况较中西部省份处于相对轻度水平,从发展趋势看,泛珠三角地区各省份零售业经营效率处于上升发展通道。
Based on the output CCR model, this paper uses DEA method to calculate and compare the operating efficiency of the retailing industry over the three years from 2012 to 2014 in 9 provinces in the Pan-Pearl River Delta. The results show that the efficiency of the retail business in the Pan-PRD region is different from that of the eastern, central and western provinces, with obvious gradient differences. The eastern region is higher than the central and western provinces in terms of comprehensive efficiency, pure technical efficiency and economies of scale. Jiangxi, Yunnan and Yunnan provinces. In the eastern region, retail sales in Guangdong Province entered the phase of decreasing returns to scale. Jiangxi and Yunnan in 2014 and Sichuan in 2013 were at constant returns to scale while other provinces were on a larger scale in three years. Compared with the central and western provinces, the redundant investment in the eastern provinces is at a relatively mild level. From the development trend, the efficiency of retail business in all provinces in the Pan-Pearl River Delta region is on the rise and development.
