湖域工业点源初始排污权配置定额模型与算法研究——以江苏省太湖流域为例

QUOTA MODEL AND ALGORITHM RESEARCH ON INITIAL DISCHARGE PERMITS OF LAKE BASIN INDUSTRY POINT SOURCE:A CASE STUDY OF TAIHU LAKE BASIN IN JIANGSU PROVINCE

针对湖域工业点源初始排污权定额配置问题,以"公平、效率、可行"为配置原则,通过引入权重系数的字典序最小化最大值方法,构建了基于多主体多种初始排污权多期配置的字典序定额模型,并给出求解算法。进而以江苏省太湖流域27类主要工业行业的初始氨氮排污权单期配置为例,从行业初始排污权短缺率与行业治污效益两方面,对比分析了基于等短缺率定额模型、等环境容量比例定额模型、字典序定额模型计算得到的3种定额配置方案效果。结果表明:相对于另外两种定额模型,字典序定额模型所得配置方案可实现平均行业短缺率最小(46.13%),平均行业治污效益最大。研究也表明在"公平、效率、可行"配置原则下,字典序定额配置方法能够更为有效的促进企业治污技术提标升级和区域产业结构升级。

This study focused on the quota allocating of initial discharge permits problem on lake basin industry point source.This paper set ＂Fairness,Efficient and Feasible＂ as the allocation princess,through the lexicographic minimax model with weight coefficient of the objects＇ initial discharge permits shortage,and proposed the lake initial discharge permits lexicographic quota allocation model and the algorithm.Taken initial NH3-N discharge permits allocation of 27 kinds main industry in Taihu Lake Basin of Jiangsu Province,from both the industry＇s initial discharge permits shortage rate and industry pollution control benefits,an empirical study is given for comparative analysis of the effects of three kinds quota allocations computed by the equal shortage rate quota model,the equal environment capacity proportion quota model,the lexicographic quota model.The result showed that：relative to the other two kinds of quota model,the quota allocation scheme computed by the lexicographic quota model achieved the lowest average industry shortage rate as 46.13%,and the best average industry pollution control benefits.And the analysis indicated that based on the ＂Fairness,Efficient and Feasible＂ allocation principles,the lexicographic quota allocation method could be more effective in promoting industry pollution control technology upgrade and regional industrial structure upgrade.
