摘要
结合新型城镇发展过程中的生态学特征,将新型城镇生态系统演化过程划分为发展和竞争两个关联子阶段,构建了两阶段超效率DEA模型,对辽宁省14个地级市城镇化演化各阶段的生态效率进行评价,并利用探索性空间数据分析(ESDA)揭示其空间特征。结果表明辽宁省新型城镇生态效率不均衡:第一阶段发展效率总体水平较高,存在显著的空间负相关特征,局部空间关联性非常弱;第二阶段竞争效率总体水平偏低,存在显著的空间正相关特征,局部空间关联性较弱。
Combined with the ecological characteristics in the process of new urban development,the ecosystem evolution process is divided into two related sub-stages of development and competition,and a two-stage super-efficiency DEA model is constructed to evaluate the eco-efficiency of each stage of the evolution of 14 prefecture-level cities in Liaoning province.Then it analyzes the spatial distribution characteristics and discusses the spatial differences of the new urban eco-efficiency based on ESDA.The results show that the new urban eco-efficiency is imbalance in Liaoning province:in the first stage,the development efficiency is higher level and exists a significant spatial negative correlation and the local spatial correlation is weakest;in the second stage,the competition efficiency is lower,exists a significant spatial positive correlation and the local spatial correlation is weaker.
