土地价值与城市增长

文章介绍了城市经济动态模型。通过利用在经济学中广泛的效用函数及对效用函数的优化 ,得出城市土地地租有三部份构成 :农业土地地租 ;土地发展成本的租金 ;和区位或可达性所带来的级差地租 ,并进一步推出城市土地价值有四部分构成 :(1)农业土地价值 ;(2 )土地发展成本 ;(3)可达性的经济价值 ;(4)可预见的未来土地地租增值所带来的价值。相对应 ,城市边缘非城市土地价值有两部分组成 :一是与农业土地地租有关的土地价值 ,另一个是可预见的土地转变成城市用地后未来土地地租增值所带来的价值。城市经济动态理论及其结论丰富和发展了土地地租和土地价值理论 ,加深了对土地价值形成和发展的理解 ,有利于相关法规和政策的制定 ,以此提高城市土地利用效益和推动城市发展。最后 ,结合中国国情 ,文章分析了城市政策及土地政策对城市化的社会经济影响。

Land values and urban growth

This paper first introduces a dynamic urban economic model developed by Capozza and Helsley (1989) and then applies their conclusion in China to better understanding the nature of urban development process and helping to shape urban policy.The model enriches the literature by linking land price and urbanization.The implication of model results is profound particularly in China policy regime since it has launched national wide effort to determinate the benchmark land use rights system.It is concluded that capital farmland protection commonly practiced in China in fact will hinder urbanization and give rise to high socioeconomic costs.Finally, the paper made suggestion and policy recommendations with regard to promoting land use efficiency and rationalizing land use allocation and management.
