摘　　要：为解决评价碳排放效率时面板数据的时间权重难以表示的问题,应用偏序集评价模型开展我国碳排放效率评价。该模型无需指标的具体权重值,只需知道权重顺序即可。通过收集我国30个省(区、市)2000—2017年的面板数据,求出历年碳排放效率,以时间逆序为权重顺序,进行碳排放效率评价。结果表明:我国东部碳排放效率较高,中部次之,西北部碳排放效率最差,影响各地区碳排放效率的因素不同,因此制定碳排放政策时要因地制宜;不同地区的碳排放效率呈空间聚集的趋势,一个地区的碳排放政策不仅会影响本地区的碳排放效果,还会影响相近地区的碳排放效果,因此要加强各地区间的碳减排合作。To address the problematic time weights of panel data in the evaluation of carbon emission efficiency,a partial-order set evaluation model was used to evaluate the carbon emission efficiency of China.In this model,it was not necessary to know the specific weight values of the indicators,but only the weight order was needed.By collecting the panel data of 30 Chinese provinces(autonomous regions and municipalities)from 2000 to 2017,calculating each year′s carbon emission efficiency,and sequencing the weight values in time reverse order,the carbon emission efficiency was evaluated.The results showed that the carbon emission efficiency was the highest in East China,followed by the Central China,and the worst in Northwest.The factors affecting the carbon emission efficiency in each region were different,which required that specific carbon emission policies should be developed according to local conditions.The carbon emission efficiency of each region tended to be aggregated,and the local carbon emission policy would not only affect the carbon emission effect of the region,but also affect the carbon emission of the adjacent areas,so,it was necessary to strengthen the cooperation of carbon emission reduction among all the regions.
