近20年来珠江三角洲区域经济时空差异的演变

Changes of Economic Disparity in the Pearl River Delta from 1994 to 2010

本文以人均GDP为主要指标,通过运用SPSS软件的回归分析模型和ArcGIS软件的空间分析模块,从时间和空间尺度对珠江三角洲1994-2010年间的区域经济差异时空演变特征进行研究。研究发现:(1)珠江三角洲区域经济差异明显,整体上呈扩大趋势,其中县域经济空间集聚差异较大;(2)经济发展空间格局上具有明显的空间集聚特征,且空间集聚性日趋显著;(3)区域经济差异呈现显著的圈层结构,区域中心城市的涓滴效应开始显现。

Based on the per capita GDP data, this paper analyzes the spatial and temporal variations characteristic of the economic disparity in the Pearl River Delta from 1994 to 2010 by using Regression analysis method and GIS spatial analysis method. It has reached the following conclusions. （1）The regional economic disparity has been on the increase on the whole, especially at the county level; （2） the regional economic disparity has some obvious spatial connection in the Pearl River Delta; （3） The regional economic disparity has an obvious layer structure, and the core city＇s diffusion effects have emerged.
