摘　　要：人口动态分布和当地的房价、生态环境质量存在相互联系,这种联系可能会影响一个地区的最优城市规模。本文采用扩展到房价和生态环境的新经济地理模型估计这种联系。居民根据差异化产品数量、房价和生态环境组成的综合效用来选择居住地,从而实现区域间的均衡。模型模拟结果表明,均衡状态下的最优城市规模随着房价、生态环境质量以及政府政策变动而变动。在福利分析中,我们研究了自由市场和政策调节两种不同情况下,城市规模差异所带来的社会福利差异。Population distribution is closely related to housing and the environment. In this paper, we used new economic geography model extended to the housing and the environment to estimate the link. Housing Prices in different regions is heterogeneous and the local ecological environment affect the price. Model results show that Degree of aggregation is dynamic, a dynamic balance may be achieved as the marginal utility of inter -regional housing and the environment arising. In policy analysis, we believe that the general welfare of the community residents most is the best, and used as criteria for analysis of the equilibrium conditions of the optimal city size.
