【摘要】 本文通过构建一个房地产市场空间竞争模型,分别就coumot竞争和价格合谋情形,探讨了开发商的位置及其密度如何影响均衡开发量、房价和社会福利。本文的基本结论是:空间竞争决定了房价,而非房价收入比;市场决定的价格不一定为合理性价格;房价与市中心距离和开发商密度成反比;空间垄断是房价刚性的根本原因。因此,要将刚性房价降下来,政府一方面应将大项目拆分为小项目,促进竞争,另一方面应对空间垄断进行管制。更多还原

【Abstract】 This Paper examines the impacts of the location of real estate developers and their intervals on the equilibrium output, housing pricing and the social welfare. The author analyzes two cases of Cournot Competition and Price Collusion respectively by setting up a spatial competition model of real estate market The basic conclusions are as follows: the housing price is determined by spatial competition, not by PIR; the price determined by market is not always rational; housing price is inverse proportional to the distance away from the core and the density of the developers; the rigid housing price is resulted from the spatial monopoly. In respond to the rigid housing price, the government has to split the big developing projects into small ones for competition, and regulate the spatial monopoly as well.更多还原
