摘要
文章结合新经济地理学、二元经济理论和内生增长理论提出了城市规模影响因素的分析框架,并基于分位数回归方法,采用2011年中国284个地级及以上城市的截面数据进行了实证研究。研究表明:随着城市规模的扩大,市场规模的影响逐渐降低;公共财政支出对高分位数城市规模的影响最大;在中等城市规模附近,知识溢出的影响最为显著;城乡收入差距对中等及中等偏上城市的影响较为显著。另外,文章分区域研究了城市规模影响因素在东部、中部和西部地区的不同特点,提出了相应的政策措施。
Based on the new economic geography, the dual economy theory and the endogenous growth theory, this paper puts forward an analytical frame- work with regard to influencing factors of urban scale and makes an empirical study by using quantile regression method and the cross-sectional data of 284 cities with the prefecture level and above in 2011. It comes to the following conclusions： firstly, with the expansion of urban scale, the effects of urban scale constantly weaken; secondly, the effect of public fiscal expenditure on high-quantile urban scale is the greatest; thirdly, the effect of knowledge spillover is the most signifi- cant under medium-sized urban scale; fourthly, the urban-rural income gap has a more significant effect on medium-sized and large cities. In addition, this paper studies the characteristics of influencing factors of urban scale in east- ern, central and western China and makes corresponding policy suggestions.
