摘要
构建海岛县循环经济评价指标体系,运用含非期望产出的DEA模型对海岛县循环经济发展效率进行评价,结果发现,海岛县循环经济效率存在明显异质性,部分海岛县属于DEA有效,而过半数海岛县属于非DEA有效。海岛县循环经济存在规模报酬差异、固定资产投资和污染物排放水平不一、三次产业占比不同等是造成这种现象的原因。纯污染排放代表的循环经济效率呈现先下降后上升的趋势,而代表资源投入的循环经济效率随经济社会发展呈现缓慢上升趋势,二者共同作用使得海岛县循环经济效率呈U型演化形态。海岛县应加强正式和非正式制度建设,将循环经济付诸实践;还要因地制宜、因县施策,促进海岛县循环经济健康发展。
The evaluation index system of circular economy in island counties is constructed,and a DEA model with non-expected outputs is used to evaluate the efficiency of circular economy development in island counties.The results show that there is significant heterogeneity in the efficiency of circular economy in island counties,with some island counties being DEA effective,while more than half of island counties are non DEA effective.The reasons for this phenomenon are the differences in the scale returns of circular economy in island counties,the different levels of fixed assets investment and pollutant emissions,and the different proportions of the three industries.The efficiency of the circular economy represented by pure pollution emissions shows a trend of first declining and then rising,while the efficiency of the circular economy represented by resource investment shows a slow upward trend with economic and social development.The combined effect of the two makes the efficiency of the circular economy in island counties evolve in a U-shaped shape.Island counties should strengthen and promote the formal and informal systems,and put the circular economy into practice;at the same time,it is also necessary to adapt to local conditions and adopt county-specific policies to promote the healthy development of the circular economy in island counties.
