太湖流域水环境变化的货币化成本及环境治理政策实施效果分析——以江苏省为例

The Regional Currencified Cost of Aquatic Environmental Change of Taihu Basin and Analysis on Environmental Policy Implemention in Jiangsu Province

首先测算1987-2001年间太湖流域水环境变化货币化成本,结果表明,1987-2001年间全太湖流域水环境呈现阶段性恶化的特征,15年间水环境变化的货币化成本增长了约1251亿元,年均增长速度达6.67 %,其中,太湖流域苏南地区2001年的水环境货币化成本已经占到该地区GDP的19%. 其次,通过构建太湖流域水环境变化政策驱动力模型,检验了太湖流域环境治理政策的运行效果,结果表明,1996年以来实施的环境政策,使得太湖流域的水环境污染货币化成本下降了61.79%,因此,太湖流域的环境治理政策是有效的. 据此,文章最后从流域产业结构调整、发展循环经济以及建立多元的环境治理投融资体系等几个方面,提出了进一步推进太湖流域环境治理的政策建议.

This article computes the currencified cost of water environment changing in Taihu Basin during 1987-2001. The deteriorated water environment in Taihu Basin has led an environment cost up to about 125.1 billion yuan with a increase of 6.67% per year. The cost accounts for 19 percents of the GDP in south Jiangshu province in 2001. Moreover, this paper has checked the effect of environment protecting policy implementation by established the policy-driving model of environmental change in Taihu Basin. The outcome suggests that the corresponding environment policy is effective because the environment policy has dropped the cost by 61.79%. Finally, this article put forward some suggestion on improving environment quality from several aspects, i.e. adjusting the industry structure, developing circulation economy and establishing the environment finance system from several channels.
