为了探索理论和实用性兼顾的水污染物排污权初始分配价格的定价方法, 在对现有排污权定价模型分析的基 础上, 通过对环境容量的资源性和价值性的探讨, 建立了支付意愿定价模型和租金分配定价模型。以河南省为例, 水污染物( 以COD 和氨氮为例) 排污权初始分配价格计算结果为: 支付意愿定价模型核算出的COD 排污权价格为 3 463 元/ t, 氨氮排污权价格为4 329 元/ t; 租金分配定价模型核算出的COD 排污权价格为4 499 元/ t, 氨氮排污权 价格为9 122 元/ t。两种定价模型均具有一定可行性, 但租金分配定价模型的定价理论更为合理, 定价结果更为可 靠, 因此推荐以租金分配定价模型为主, 以支付意愿定价模型为辅来进行水污染物初始排污权的价格制定。

The purpose of the study w as to ex plor e the metho d that combines bo th theor y and utility. On the basis of pricing the2 o ry of paid use of emission rig hts, by ex plor ing the r eso ur ces and v alue of the env ir onmental capacit y, the conting ent v alue pr i2 cing method and the rent allocatio n pricing model wer e established. Then, the initial distr ibut ion pr ices o f emission rights in Henan pr ov ince w ere calculated using abo ve two metho ds. Result s show ed that the emission pr ice of COD and ammonia was re2 spectively 3463 and 4329 y uan per ton w hen using the conting ent value pricing met ho d, which wer e 4499 and 9122 y uan per ton when using the rent allocatio n pricing mo del. The two mo dels are both feasible. By compar ing the tw o models, our finding s indi2 cate that the theor y and results of the r ent allocatio n pricing mo del ar e mo re reasonable. T her efor e, rent allocatio n pricing mo del may be recommended as a main metho d, and the co nt ing ent value pricing model can be used as an aux iliar y means.
