基于2001-2013年长三角25个城市会展场馆数据，用核密度估计和空间自相关方法，分析了场馆分布从区域中心向副中心扩散的集聚特征，并识别出城市地位、经贸发展、产业政策等主要影响因素。
This paper is about the distribution and spatial agglomeration characteristics of exhibition venues based on an analyze of exhibition venues data of 25 cities selected in Yangtze River Delta from the year 2001 to 2013, using kernel density estimation and spatial autocorrelation research methods.
