基于探索性空间分析的东北经济区城市竞争力研究

Study on Urban Competitiveness within Northeastern Economic Zone of China Based on an Exploratory Spatial Data Analysis

利用空间探索性数据分析方法,选择构建城市竞争力指标,对东北经济区36个地级市2003-2005年竞争力进行全局和局部空间相关分析,揭示东北经济区城市竞争力的空间自相关性、空间异质性以及空间相互作用机制。研究表明,东北经济区36个城市中,城市之间的发展存在空间相关性,该区域城市发展整体上存在着明显的空间聚集现象,2003-2005年城市竞争力的空间聚集程度在不断加强。城市竞争力的空间异质性主要表现为竞争力较高的城市位于东部和南部,竞争力较低的城市位于西部,并且趋于聚集,经济发展区域性明显;纵向比较,在3年内东北经济区城市竞争力得到一定的发展,相邻城市空间差异性在减小,城市竞争力趋于均衡。

Based on the urban statistical data of Northeast China during 2003-2005,the urban competitiveness was analyzed by the global and local spatial autocorrelation to reveal the spatial autocorrelation,spatial heterogeneity and the mechanism of spatial interaction.The results are as followed：spatial autocorrelation exists in competitiveness among the whole 36 cities of Northeast China.It shows that there is holistic spatial agglomeration in the urban economic development,and the degrees of spatial agglomeration become more and more strengthened from 2003 to 2005.For the urban competitiveness of spatial heterogeneity it can be found that the competitiveness of the eastern and southern cities is better than those in the west,and this phenomenon tend to strengthen in agglomeration.At the same time,the urban competitiveness has been improved during 2003-2005 while the difference of adjacent cities decreased.The regional urban competitiveness tends to balance.
