摘要
以全国40个矿业城市为研究对象,建立基于矿业城市发展的效率评价指标体系,运用传统数据包络法(DEA)和交叉数据包络法(DEA)分别评价40个矿业城市的综合效率,并运用σ收敛检验矿业城市效率的整体离散程度.结果表明,我国矿业城市效率普遍很低,城市之间的差异较为显著;中部和东北要高于东部和西部,煤炭型城市和冶金型城市要高于油气型城市和综合型城市,中小城市效率要高于特大城市和大城市,幼年矿业城市效率要逐渐高于老年和中年矿业城市,并且不同区域、不同类型、不同规模、不同阶段城市之间的差距均有所变化,明确了各矿业城市目前所处的阶段,以及未来发展的潜力和改进的方向.
Abstract
With 40 mining cities in China as the research objects,efficiency evaluation was established based on mining city development.Traditional data envelopment analysis (DEA) and cross DEA were used to evaluate the σ comprehensive efficiency of 40 mining cities.The convergence was applied to test the overall discrete degree of mining cities efficiency.Results showed that mining cities in China has relatively low efficiency with relatively significant differences.Central and northeast China were higher than the east and west China.Coal city and metallurgy city were higher than oil and gas city and comprehensive city;small-and medium-sized cities had higher efficiency than megacity and metropolis.Young mining city had higher efficiency than old-and middle-aged mining cities.Differences changed among different regions,types,scales and stages.Induction of the two virtual DMU made clear the stage of each mining city,as well as the development potential and improvement direction in future.
