Research on Environmental Efficiency Evaluation of Urban Agglomerations in Northeast China Based on DEA Model
以东北三大城市群为对象，用DEA方法评估其十一五期间的环境保护产业集聚效应及经济环境协调状况，发现中南辽宁城市群经济水平最高但环境压力最大，各城市群环境效率均有提升空间。
With the Twelfth-Five-Year Plan of Northeast revitalizing,how to implementing the revitalization of the scientific development,the transformation development,the coordinated development,the innovative development,determines the future development direction and development level of the northeast areas.This paper takes the three urban agglomerations in Northeast China as the research object,applies DEA method to evaluate industrial cluster effect of environment protection and the coordination of economy and environment status during theEleventh-Five-Year period.The results showed that:the urban agglomeration of the Central and South Liaoning Province belonged to the highest economic development level,but it resulted in maximum pressure to environment;the coordination of economy-environment status for the urban agglomeration of Central Jilin Province and the urban agglomeration of Ha-Da-Qi was also very poor;three Urban agglomerations had great space to improve their environmental efficiency.The paper suggests to optimize the spatial arrangement of industrial cluster,to establish division of labor and harmonious mechanism of inside and between the urban agglomerations,so as to promote economic and environmental coordinated development in Northeast China.
