重庆区域经济发展的时空差异分析

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 economic development statistics of various regions of Chongqing from 2000 to 2010,this paper uses principal component analysis in combination with the function of space analysis of Arcgis 9.3 to study the characteristics of economic development of Chongqing and its evolution trend.On the whole,the level of economic development of Chongqing has been greatly raised in recent years,though the inter-regional differences remain rather obvious.With a spatial distribution pattern of "One Circle and Two Wings" of the city,the level of economic development of the Circle is more remarkable than that of the Two Wings.The level of economic development of a region appears inversely proportional its spatial range.The spatial disparity of regional economic strength presents a sphere structure in the Circle and presents a single weak nucleus structure in the Two Wings.The economic strength of Chongqing from 2000 to 2008 follows the pattern of spatial distance attenuation,and the one Circle is always higher than the Two Wings.The boundary of the high-level regions is extending;the position of the primary urban area is steadily improved,and the difference between the One Circle and the Two Wings is still obvious.
