Abstract:

Circular economy is the only way to sustainable development of resources-based cities. This paper, based on DEA model, incorporates the resources comprehensive utilization and wastes circular utilization into the evaluation system, establishes DEA model in circular economy, which is applied in 9 resources-based cities, Harbin, Jixi, Hegang, Shuangyashan, Daqing, Qitaihe, Mudanjiang, Heihe and Daxing^，anling to evaluate the relative effectivity and technical effectivity in circular economy with suggestions. Harbin, Daqing and Daxinganling are developing well in circular economy, Mudanjiang and Heihe are at a junior stage with technical effectivity but decreasing benefits, and the other four cities are lagging which is an obstacle in Heilongjiang^，s circular economy.

Key words: DEA model, circular economy, resourcesbased cities, scale effectivity, technical effectivity

摘要：

循环经济是资源型城市可持续发展的必经之路。在DEA模型的基础上，将资源综合利用和废弃物循环利用等指标纳入评价系统中，构建了循环经济DEA模型。应用循环经济DEA模型对黑龙江省9个资源型城市包括哈尔滨市、鸡西市、鹤岗市、双鸭山市、大庆市、七台河市、牡丹江市、黑河市和大兴安岭市循环经济发展的相对有效性和技术有效性进行评价，并给出各个城市循环经济发展的建议。结果表明：哈尔滨市、大庆市和大兴安岭市循环经济发展良好；牡丹江市和黑河市为技术有效但是规模收益递减的决策单元，循环经济处于初级阶段；其他4个城市循环经济发展较为落后，是黑龙江省循环经济发展的阻碍因素。
