摘要
基于Krugman理论模型,利用GIS技术,从地理和经济两个视角,探索城市体系的演变过程,并分析城市数量和分布的理论规律。结果显示,在地理和经济的非均质空间下,城市数量与制造业劳动力份额、需求价格弹性和可达性都有很大的相关性,且城市易于在人口比较密集的地区形成。
Based on the Krugman model, using GIS technologies, from the perspectives of geographic and economic, we explored the evolution of urban system and analyzed theory regularity of urban distribution and number. Results show that the number of Cities is highly relevant to share of laborers in the manufacturing sector, constant price elasticity of demand, under the non-homogeneous spatial of geospatial and economic. Cities are relatively easy to form in densely populated areas.
