RESUMO
Objective To explore the applicable method for the quantitative valuation of health economic loss by environmental pollution.Methods The contingent valuation method(CVM) and human capital method were respectively used to valuate the health economic loss by air pollution in Beijing and the comparison of the results was conducted.Results In 2005,the economic benefit of main air pollutants reduction by 50% in Beijing was 2.183 billion Yuan estimated by human capital method,and it was 10.891 billion Yuan estimated by CVM.The result of CVM is 4.99 times as high as that of human capital method.Conclusion CVM is a well recommended technique which can be used to estimate the total value of health loss by environment pollution,and this empirical study proved that it is feasible to estimated health economic loss in China.Further studies are needed to improve the efficiency of evaluation.
RESUMO
Environmental pollution could affect human health.The valuation on economic health loss due to environmental pollution could assist environment management to set more efficient environment policy.Contingent valuation method(CVM)is the worldwide used method to value loss caused by environmental pollution.CVM is a state preference non-market valuation method,which can flexibly assess the full economic value of public goods.CVM has been rarely used in environmental health loss valuation in China.Economic theory,application technique of CVM and it's potential bias was reviewed and discussed in this paper.Compared with the other methods,it could be concluded that CVM is a promising tool to value health loss by environment pollution in China.
