采用一般均衡的方法,从供给和需求的角度,得出自然资源是中国城市化快速发展硬约束的结论。在自然资源约束下,资源最优配置的结果表明:城市化水平与城市化质量之间存在替代关系。在此基础上,对均衡结果进行了比较静态分析,研究表明:经济全球化有利于增加自然资源的供给,城市化道路的偏好直接影响到城市化水平。针对中国城市化快速发展面临劳动力转移和城市化质量提升的双重压力,提出了转变经济增长方式,城市化数量和质量并重的政策建议。

China has entered the stage of rapid urbanization since 1996.The paper makes a con,clusion that natural resource is a strong restriction of rapid urba nization of China by adopting general equilibrium method in terms of supply and demand.Urbanization includes two aspects, one is urbanization quality and the ot her is urbanization level.This paper divides natural resources into two categori es,one is for production purpose and the other for living.In theory,we can subst itute urbanization level approximately with resources for production,so is the c ase of urbanization quality with resources for living.Under restriction of natur al resources,the optimum result of resources distribution indicates that there i s a substitutional relationship between the urbanization level and urbanization quality.On the basis of the above discussion,we make a comparative static analys is on the equilibrium result.Both change of natural resources endow,ment and fu nction utility will lead to variations in equilibrium result.The study shows tha t the economic globalization is favorable for the increase of the supply of natu ral resources,and the preference of urbanization road directly influences the ur banization level.Facing the double pressure of labor force transferring and prom oting urbanization quality in the rapid urbanization process of China,both the u rbanization quality and quantity should be regarded as equally important,and the mode of economic growth should be changed.
