项目摘要

Recently, sea level rise due to global warming is recognized as the great international environment problem that is becoming increasingly serious. It is said that sea level rise will give manifold impact to beginning with socio-economy, and that its magnitude will be great as some countries are destroyed. This study constructs a population migration model on GIS (geographic information systems) and a socio-economic model in the framework of general equilibrium analysis, and prospects population migration and economic loss due to sea level rise in Ise Bay Area (especially Aichi Prefecture). As the result, population migration and economic loss due to lm of sea level rise can be shown on maps in Jse Bay Area.And this study evaluates the change of WTP (willingness to pay) by difference of payment measures in CVM (contingent valuation method) and to make clear that the fair impression to payment influences the result of WTP. Then a questionnaire survey that asked WTP to some countermeasure against sea level rise was carried out, where two kinds of payment measures (money paid equally and money paid only favorite) and three kinds of payment unit (every month, every year and once in ones life) were set up. On the other hand, an analysis model that incorporated the fair impression by difference of payment measures as the variable was constructed. The result indicates that the values of WTP are changed by payment measures ; the WTP measured by the money paid equally is higher than the WTP measured by the money paid only favorite.

最近，由于全球变暖导致的海平面上升被认为是一个日益严重的国际环境问题。据说海平面上升首先会对社会经济产生多方面的影响，而且由于一些国家被摧毁，其影响将是巨大的。本文构建了基于地理信息系统的人口迁移模型和一般均衡分析框架下的社会经济模型，并对伊势湾地区（特别是爱知县）海平面上升造成的人口迁移和经济损失进行了展望。因此，Jse Bay Area的人口迁移和海平面上升造成的经济损失可以在地图上显示出来。本研究通过条件评估法（CVM）中不同的支付手段来评估支付意愿的变化，明确对支付的公平印象影响支付意愿的结果。然后进行问卷调查，要求WTP对海平面上升采取一些对策，其中设置了两种支付措施（平等支付和只按偏好支付）和三种支付单位（每月，每年和一生一次）。另一方面，构建了以不同支付方式的公平印象为变量的分析模型。结果表明，支付措施会改变WTP的值；平均支付的金钱衡量的WTP高于只支付的金钱衡量的WTP。
