基于ESDA的中国长三角地区创新空间分异及演进研究

摘要

以长三角地区的25个城市为观测对象,运用探索性空间数据分析(ESDA)方法,研究了2005-2014年长三角地区创新的空间相关性.结果显示;长三角地区的创新呈空间锁定现象,且其空间分布不均衡;创新集中在上海、杭州、南京、苏州及其相郐城市;远离这些创新中心城市的创新则不够活跃.Moran指数的计算结果表明,长三角城市群的空间联系愈加紧密,但是强弱分化也非常明显.时空跃迁测度结果显示,创新表现出明显的空间分层性,且空间分布格局不易变化.%This paper analyzes the spatial correlation of innovation in 25 cities in Yangtze River Delta from 2005 to 2014 by using the method of spatial exploratory data analysis(ESDA).The result shows as follows:innovation presents a certain space-locked,and the spatial distribution of innovation is unbalanced;the innovation mainly concentrates in Shanghai,Hangzhou,Nanjing,Suzhou and their adjacent areas;the innovation in other cities which are far away from these central cities are not active.Moran index shows that the spatial agglomeration of innovation in Yangtze River Delta is more closely,but strong and weak differentiation is also very obvious.The result of transition measures of space and time shows that innovation presents obvious spatial stratification,and spatial heterogeneity is not easy to change.
