Discussion on the Application of Economic Approaches for Environmental Health Impact Assessment / 环境与健康杂志

ABSTRACT

There are multiple sophisticated approaches that can be used in estimations on health effects resulting from environmental pollution. By comparison, human capital approach and averted expenditure approach are not suitable to be the first choice because of the insufficient capability of capturing all aspects of health effects. Date availability and estimation extrapolation limit the application of hedonic wage approach and hedonic price approach. It has been accepted universally for the flexible technique provided by contingent valuation approach that any health effects can be separately evaluated depending on researchers' purposes. Based on the powerful macroeconomic theory, general equilibrium theory, the CGE model is powerful to simulate the mechanism of interaction between multi-sectors with a national economic system so as to objectively reflect the health impacts on national economy due to environmental pollution.
