City formation with complex landscapes

Using simulation methods I explore some of the properties of the new economic geography model using a complex landscape. I introduce landscape complexity by allowing the existence of limited pathways that can be traversed at a lower cost than most other paths. I also introduce a river that may be crossed at limited points and may be used to transport goods. I find that adding complexity substantially alters how many cities form and where they form. Compared with a simple landscape, complex landscapes produce a distribution of city sizes that more closely resemble the actual distribution of city sizes.  

金融集聚的区域差异及影响因素的空间计量分析

运用空间计量方法，利用31省市2005~2010年的相关数据对我国金融产业集聚的影响因素进行实证研究,研究表明：中国金融产业存在不断增强的正向空间自相关性与空间集聚性，邻接地区的金融产业集聚具有溢出效应；资源禀赋能部分解释中国金融产业区域集聚，在控制新经济地理与产业政策因素影响下，资源禀赋因素对金融产业集聚的影响不再显著；新经济地理变量和产业政策变量对金融集聚有正的促进作用；中国金融产业区域差异明显，呈现东高西低的分布格局。
