地震巨灾风险的特点是低频高损,历史震害数据缺乏、风险暴露快速变迁等因素导致基于大数定理的费率厘定方法无法针对各区域不同建筑类型的风险暴露进行精细化定价。本文基于“五代图”潜在震源区模型的随机事件集解决观测数据不足的问题;并使用“五代图”所采用的地震动参数衰减关系模型与工程易损性方法计算地震事件对风险暴露造成的损失,从而计算费率厘定、地震风险管理需要的必备参数。本文采用云计算平台的弹性伸缩计算技术,实现动态按需分配计算资源,满足多用户并发使用的业务需求;同时采用以业务数据为单元的数据隔离方案,构建支持多租户的高性能地震保险损失评估SaaS云平台。  相似文献

Pricing China's irrigation water   总被引:1,自引:0,他引:1  
Many development agencies and other actors are advocating that China adopt a system of water markets or of high water prices in order to resolve the inefficiencies of irrigation agriculture and to supply sufficient water for growing urban and industrial uses. We argue that this proposal rests on a series of propositions: that the price of water is too low to encourage farmers to be efficient; that farmers are not charged volumetric prices and so are not encouraged to conserve water; that water is scarce largely because farmers are profligate in their use of water; and that proper pricing of water will not affect equity. None of these contentions is true. Farmers have to pay not only the official charges for water but also the much higher costs of pumping it onto their fields. Once pumping is included, farmers are paying prices that are volumetric. Furthermore, the inefficiency of farmers arises in large part from the manner in which water is delivered to them: the system offers no rewards for care in the use of water and instead rewards greed. And, finally, although it might be true that higher prices do not affect equity within a village, in fact they would have substantial effects on inter-sectoral equity, with farmers becoming worse off in comparison to urban dwellers. The paper concludes by sketching a more appropriate scheme for raising the efficiency of use of irrigation water.  相似文献

This paper aims to support arguments that Parr and Knox-Hayes developed in two recent articles published in Geoforum against neoliberal market-oriented policies in the environmental realm. We advocate for distinguishing between epistemological, ethical and political arguments in order to tackle the political economy, which the neoliberal pricing metric relies on. We suggest that North’s institutional individualism and Sen’s capabilities approach offer consistent and relevant theoretical frameworks for overcoming the failures of mainstream economics.  相似文献
