    摘要:

    利用考虑多维产出的零和收益-数据包络分析(ZSG-DEA)模型测算2000—2017年中国大陆31个省级行政区(以下简称省)在水资源污染排放总量固定下的污染综合分配效率及生产、生活与生态3个维度的产出效率,并基于效率最大化原则对2017年各省污染排放额度进行调整。结果表明:31个省污染综合分配效率的平均值由2000年的0.322上升至2017年的0.364,生产维度产出效率是拉动污染综合分配效率提升的主要动力;2000—2017年31个省污染综合分配效率的平均值为0.341,生态产出过量与生活维度产出不足导致污染综合分配效率处于较低水平;污染综合分配效率、生态维度产出效率与生活维度产出效率受经济发展水平影响较小,而生产维度产出效率受经济发展水平影响较大;污染综合分配效率分布由大到小为东部、西部、中部,生产维度产出效率分布由大到小为东部、中部、西部,生态维度产出效率分布由大到小为西部、中部、东部,生活维度产出效率分布由大到小为西部、东部、中部;各省污染排放调整额度与污染综合分配效率呈正相关关系,北京、天津、上海、浙江、青海与西藏等20个效率较高的省可增加污染排放额度,河北、安徽、河南、江西与湖北等11个效率较低的省需降低污染排放额度。

    Abstract:

    This study used the zero sum gains-data envelopment analysis(ZSG-DEA)model, with consideration of multi-dimensional outputs, to estimate the pollution comprehensive allocation efficiency and the output efficiencies of production, life, and ecological dimensions of 31 provincial administrative regions(hereinafter referred to as provinces)in the Chinese mainland from 2000 to 2017 under the fixed total amount of water pollution discharge. Based on the principle of efficiency maximization, the pollution emission quota of each province in 2017 was readjusted. Results are as follows: the annual mean value of pollution comprehensive allocation efficiency of 31 provinces increased from 0. 322 in 2000 to 0. 364 in 2017, and the production dimension output efficiency was the main factor to promote the pollution comprehensive allocation efficiency; the mean value of pollution comprehensive allocation efficiency of 31 provinces from 2000 to 2017 was 0. 341, and the excessive ecological dimension output and insufficient life dimension output led to a low value of pollution comprehensive allocation efficiency; the pollution comprehensive allocation efficiency, ecological dimension output efficiency, and life dimension output efficiency were less affected by the economic development level, while the production dimension output efficiency was seriously affected by the economic development level. Moreover, the eastern region had the highest value of pollution comprehensive allocation efficiency, followed by the western and central regions; the eastern region also had the highest value of production dimension output efficiency, followed by the central and western regions; the western region had the highest value of ecological dimension output efficiency, followed by the central and eastern regions; and the western region also had the highest value of life dimension output efficiency, followed by the eastern and central regions. There was a positive correlation between the adjustment amount of pollution emission and the pollution comprehensive allocation efficiency. Twenty provinces with higher efficiencies, including Beijing, Tianjin, Shanghai, Zhejiang, Qinghai, and Tibet, could increase the pollution emission quota, while 11 provinces with lower efficiencies, including Hebei, Anhui, Henan, Jiangxi, and Hubei should reduce the amount of pollution emission quota.
