| 摘 要： | 本文以我国东部沿海三大经济区域——环渤海、长三角、珠三角为研究对象,依据空间统计学的空间自相关方法,采用以高速公路里程数为影响因子改进的空间权重矩阵,以及全局和局部Moran I指数模型,通过ArcToolbox空间分析工具分析三大区域经济空间格局。研究结果表明,长三角与珠三角区域发展呈显著的空间正相关,长三角地区较之其他两地区发展最为成熟,发展极辐射大。同时地理环境对于区域经济发展作用明显,发展核心城市集中于沿江地区或平原地区。

Spatial autocorrelation analysis on local economy of three economic regions in Eastern China |

| Abstract: | This paper used the spatial autocorrelation method to analyze the similarities and differences of spatial arrangement in the three major economic regions of eastern coastal areas in China,which is marked as the Bohai Sea region,the Yangtze Delta region and the Zhujiang Delta region.To make the analysis,the Global and Local Moran's I index,along with the spatial weighted matrixes which is revised according to the total mileage of highway,were used as the model,while the ArcToolbox was used as the spatial analyst tool.The result showed that the Yangtze Delta region and the Zhujiang Delta region present significant positive spatial autocorrelation.Compared with the other two regions,the Yangtze Delta region is in a more advanced status and its development pole is greater.Meanwhile,the geographic environment has an impact on the regional economic development.The core cities gather in plain and riverside areas. |
