摘要:

大多数经济活动发生在城市,城市作为一个区域的增长极,又带动整个区域经济的发展,对于处在工业化中期阶段的珠三角地区尤其是这徉。但是城市为什么会增长?本文运用新经济增长理论和新经济地理理论的框架,探讨经济活动密度在城市增长中的规模收益递增效应。文章的第一部分指出了当前理论界在城市规模增长研究方面的主要成果和不足;第二部分讨论了三个在不同假设条件下关于城市人口规模与城市增长、经济活动密度与城市增长的模型;第三部分采用珠三角地区和香港的数据资料对理论模型的主要部分进行了回归分析和比较分析。得出的结论是:不管是在外部经济模型还是在外部经济前提下再考虑企业的垄断竞争或考虑人力资本的模型中,区域增长极的经济活动密度既是集聚的结果,反过来它又促进规模收益递增从而加速增长极的增长。因此经济活动密度在一定的递增区间内可以成为城市的主要内生增长源。本文既对廖什用市场密度来确定城市体系区位的方法提供了理论依据,又为区域经济的发展指出了一条以点轴经济系统带动全区域经济一体化的有效途径。

Abstract:

Most economic activities occur in cities. A city, as a regional pole of growth, drives the whole regional economics to develop. There is such a situation especially in the region of Zhujiang Delta in the medium-term of industrialization. But what is the cause of urban growth? In this paper we utilize the framework of new economic growth and new economic geography and try   to study the effects of increasing scale return of the density of economic activity. The paper starts by discussing the related literature and points out that there are some puzzled things at the studies about sources of urban scale’s growth in the economic theoretical circles. In Section 2, we analyze three models about the relation of city size of population and urban growth and the relation of the density of economic activity and urban growth under different hypotheses. In Section 3, we utilize the data of the region of Zhujiang Delta and Hong Kong to make regression analysis and comparison analysis. The main result is summarized in Section 4, that is: from the perspective of the external-economic approach, the monopolistic competition approach or the human capital approach under the premise of external-economy, the spatial density of economic activity is the result of agglomeration on one hand and on the other hand it can also promote the returns of scale economics and accelerate urban growth. So the density of economic activity can become the main endogenous source of aggregate increasing returns in the certain increasing range to promote urban growth.This paper both gives a theoretical basis for August Losch’s way to determine the location of city system in market density and shows a very effective path to drive the regional economic integration through the point-axle economic system for regional economic development.
