基于生产函数的城市经济水平影响因素差异研究

改革开放以来,中国经济有长足而稳定的发展.对于一个国家或城市的经济而言,经济发展水平的提高可以通过两种途径来实现,即增加生产要素投入和技术进步.利用柯布-道格拉斯生产函数模型,分析规模经济对中国城市经济的影响.考虑到经济增长各地区间的差异性,将中国283个地级以上城市划分为6大经济区域及3个规模级别分别进行研究.研究发现,当前中国城市整体处于规模收益递增阶段,但不同区域不同规模的城市其规模弹性存在较大差异.在此基础之上,将产业结构、开放程度、与外界区域经济联系及科技水平4个具体反映广义技术进步的因素融入上述模型中,探究各因素对我国经济水平的作用,并得出了产业结构和科技水平是影响目前城市经济水平主要因素的结论.

Study on Cities' Economy Growth Factors Based on Scale Economy in China

The economy of China has been growing at high speed since the Reform and Opening Policy.For a country or a city,the continuous growth of output can be realized by two ways:increasing input of production factors and technical progress.This paper analyzes the affection of scale economy to the economic growth of China,using Cubb-Douglas urban aggregate production function.Considering the effect diversity caused by locating in different economic region and different urban scale,they divided the 283 cities at pr...
