贸易对环境影响的初步研究

根据环境经济系统的双层结构建立了贸易对环境影响的概念模型 ,即贸易通过环境类、经济类物品和服务的输入输出 ,对环境子系统直接或通过经济子系统间接产生影响 ;对影响环境的贸易 (外部因素 )与环境成本内部化(内部因素 )问题 ,分别进行了分析 ;就贸易对环境影响的研究方法问题 ,运用局域均衡模型 ,为局域贸易环境问题的量化分析提供较为便捷、可靠的模式进行了初步探讨。

Preliminary Study on Trade's Impact on Environment

The paper establishes the conceptual model of trade's impact on environment according to the double layer structure of environmental-economic system, that is, the direct and indirect effect on the environment subsystem from input and output of environmental and economic kinds of goods and services. The trade activity (external factor) affecting environment and the problem of environmental cost internalization (internal factor) are also analyzed and discussed. For the problem of research method, the partial equilibrium model is applied which offers convenient and reliable pattern for the quantitative analysis of trade-environment problem.
