项目摘要

It is of importance of environmental policy assessment by doing economical valuation of the study in East Asian countries that have several stages of economical growth. In particular, we estimated the welfare effects of environmental policy in developing countries by focusing on social benefit of health effects and valuating. In this study, we surveyed in East Asia by using Contingent Valuation Method (CVM) that has been developed in Europe and America as the method of benefit estimation. And we surveyed at Higashihiroshima in Japan by using Conjoint Analysis (Choice Experiment). The reason that conducted Conjoint Analysis survey at Higashihiroshima was to consider the effect of survey methods by doing the different method from CVM. We considered the confidence of health effects in risk reduction in Japan. The subject of risk is the death risk by the origin of air pollution and traffic accident.There is Value of Statistical Life (VSL) as one of the method to evaluate health benefit in environmental policy. VSL is that divided Willingness To Pay (WTP) for reduction of the death risk by width of reduction of the death risk. In this study, we estimated VSL based on the result of CVM and Choice Experiment. As a result, we got the findings. Population characteristics did not have the effects on VSL in the case of air pollution but had the effects on VSL in the case of traffic accident. It is also necessary to consider on the risk characteristics from now.Because VSL for GDP per capita has the differences by the district and the method of survey, VSL for GDP per capita is to be considered the cause by using Meta Analysis from now.

对处于不同经济增长阶段的东亚国家进行经济评价，对于环境政策评价具有重要意义。特别是，我们通过关注健康影响的社会效益和评估来估计发展中国家环境政策的福利影响。在本研究中，我们使用了欧美发展起来的条件价值评估法(CVM)作为收益估计方法，对东亚地区进行了调查。并采用联合分析(选择实验)对日本东广岛进行了调查。之所以在东广岛进行联合分析调查，是为了考虑不同调查方法的效果，采取与CVM不同的方法。在日本，我们考虑了健康效应对降低风险的信心。风险的主体是空气污染和交通事故的来源造成的死亡风险，在环境政策中有统计寿命价值(VSL)作为健康效益评价方法之一。VSL是死亡风险降低的支付意愿(WTP)除以死亡风险降低的幅度。在本研究中，我们根据CVM和Choice实验的结果来估计VSL。结果，我们得到了调查结果。在空气污染的情况下，人口特征对VSL没有影响，而在交通事故的情况下，人口特征对VSL有影响。由于人均GDP的VSL因地区和调查方法的不同而存在差异，因此从现在开始使用Meta分析将人均GDP的VSL视为原因。
