新加坡组屋与中央公积金政策分析     

陈志刚 《国土资源情报》2014,(1):2-11

新加坡住房保障是按照政府分配为主、市场出售为辅的原则。组屋的建设用地来自于国有土地转让和私有土地征收;资金来自于物业租赁、管理和服务收入、政府贷款、组屋出售收入;组屋类型包括新HDB组屋、乐龄公寓、私人组屋、执行共管公寓,通常是按照"先售后造"、"按需而造"的方式来满足不同人群的需求;在组屋购入且住满几年后可以在二级市场上转卖。在新加坡,之所以能修建大量的组屋,原因之一是背后有完整的中央公积金制度支持。公积金制度的基本功能是为退休后提供养老保障,如今又拓展到医疗、住房、家庭保障、资产投资等方面,成为一项综合性的保障项目。  相似文献

The preservation of farmland is a growing concern in China because the fact that China possesses limited land resources and the world's largest population presents a clear contradiction. Only when the value of farmland is fully appreciated in commercial markets can farmland preservation be effectively achieved. The current study constructed a model to evaluate the economic, social, and ecological value of farmland in China according to the connotation of values. As a case study, the value of Chinese farmland was estimated in 1999, 2002, 2005, 2008, and 2011 using the established model. Although the amount of farmland was greatly reduced from 1999 to 2011 due to constructive occupation, agricultural restructuring, ecological restoration, and disaster destruction, the value of this farmland increased from 220.71×1012 to 736.26×1012 RMB Yuan as a result of the multifunctional nature and scarcity of farmland during the same period. The potential value of farmland in China was huge, but the value in the market was greatly underestimated, especially in regard to its social and ecological value. This study proposes a new method that integrates the discounted value of all future services provided by a natural resource(for the society and individuals) to evaluate the resource assets, provides a scientific foundation for the preservation and operation of farmland assets, and explores ways to increase farmers' property income.  相似文献
