摘要
使用投入产出模型研究了中国工业各部门的生产增加值与其废水排放量之间的关系,提出了完全废水排放系数的计算方法,计算出工业各部门的直接废水排放系数和完全废水排放系数,并对两种废水排放系数的变化原因进行分析,根据废水处理效果的不同给出政府对相应的工业部门应该采取的治理措施,并认为废水排放治理要综合考虑产业结构、管理水平和生产规模等方面的因素,仅仅考虑提高废水处理技术是不够全面的。
The relationship was examined between the added value of all industrial sectors and the corresponding amount of wastewater emissions of each in China with the input - output model. Then this paper advanced the methods for calculating the coefficient of complete wastewater discharge, via which the coefficients of both the direct wastewater discharge and the complete wastewater discharge were calculated. Further, the causes which incur the change of both the coefficients were discussed, and then the policies of emission control tailored for different industrial sectors were proposed. Finally we argued that policies for regu- lating wastewater treatment enforced by considering only the enhancement of treatment technology but the industrial structure, management efficiency, production scale and other factors were lopsidedly arbitrary.
