在对2000-2010年重庆市各区域经济发展数据进行统计的基础上,采用主成分分析法并结合Arcgis 9.3空间分析功能,对重庆经济发展特征与趋势进行分析,结果表明:近几年,重庆经济发展水平整体显著上升,但各区域间的差异仍比较明显;在“一圈两翼”这一空间格局下,区域经济发展水平呈现出“一圈”高、“两翼”低的态势,经济发展水平与区域空间范围成反比;“一圈”内经济发展水平呈现出圈层分布,“两翼”内则出现具有一个弱核的单中心结构.2000-2010年重庆经济发展水平遵循空间距离衰减规律,“一圈”始终高于“两翼”;经济发展水平较高区域空间范围不断扩大;主城区中心地位不断提升,“一圈”与“两翼”间经济差异仍比较明显.
Based on the statistics of the economic development data of Chongqing in 2000-2010, using principal component analysis and ArcGIS 9.3 spatial analysis, the characteristics and trends of economic development in Chongqing are analyzed. The results show that in recent years, Chongqing The level of economic development as a whole has risen significantly, but the differences among different regions are still quite obvious. Under the spatial pattern of “one circle and two wings”, the level of regional economic development shows “high level” and “two wings” Low level and the level of economic development is inversely proportional to the scope of regional space; the level of economic development in the “circle” shows a distribution of circles, and a single-center structure with a weak nucleus appears in the “two wings” .2000-2010 The level of economic development in Chongqing conforms to the decay law of spatial distance, the “one circle” is always higher than the “two wings”; the region with a high level of economic development has been expanding its space; the central status of the main urban area has been continuously improved; Economic differences with the “two wings” are still more obvious.
