我国区域经济的不平衡发展是政府和社会普遍关注的问题。针对城乡之间的较大尺度上的空间差异研究已经受到普遍的关注，但对经济发展迅猛的特大城市(如北京、重庆、上海等)内部贫富差距加大的现象尚未引起足够的重视，而这种现象有可能成为经济可持续发展和社会稳定的严重隐患。因此，正确认识特大城市内部的经济差异及演变趋势，是实现区域协调发展的重要条件之一。本文采用探索性空间数据分析方法，以北京市18 区/县的人均GDP作为评估标准，分析了北京市18 区(县)在2001-2007 年，即2008 年奥运会筹备期间的经济发展的空间格局及其变化规律。分析结果表明北京市人均GDP的空间分布自2005 年后开始有向负的空间自相关性发展的趋势，暗示北京各区县的经济发展局部分异正在逐渐拉大，并显示由过去的南低北高的经济发展差异格局逐步转变为中心高周边低的空间分布格局。

The unbalanced development of regional economy in China has been a ubiquitous socioeconomic phenomenon. Recently, in order to adjust the east-west and south-north polarization patterns on a large scale, the government has put forward some significant strategic decisions, such as the western development and the rejuvenation of old industrial bases in Northeast China. However, due to the less attention paid to the unbalanced economical development in the rapidly developed megalopolises, such as Beijing, Chongqing and Shanghai, the gradually expanded regional economic disparities in megalopolis may affect the sustainable development of economy and the social stability. Understanding the economic disparity in megalopolis and its developing trend is an important precondition to promote the harmonious development of regional economy. This paper aims to study the space-time dynamics of economic development in Beijing during the preparation period of the 2008 Olympic Games (2001-2007), using exploratory spatial data analysis (ESDA). ESDA emphasizes the significance of spatial interactions and geographical location in the studies of regional economic development. By identifying spatial autocorrelation and spatial heterogeneity, the economic performance can be characterized over time. Therefore, ESDA is a powerful tool for revealing the development of regional economic disparities. Previous studies have been implemented on this issue existing in Europe and the Huaihai Economic Zone of China by using ESDA. However, few of them revealed the space-time dynamics of regional economy in inner megalopolis. This study, combining ESDA with GIS technology, attempts to investigate the development of regional economy in Beijing from 2001 to 2007. Our method is based regional per capita gross domestic product (GDP) at a county level . The results do not show strong evidences of global spatial autocorrelation, but present clear evidences of local spatial autocorrelation and spatial heterogeneity in the distribution of regional per capita GDP. From 2001 to 2007, the economic disparity in Beijing was not improved, and even enlarged. Moreover, a new centre-surrounding polarization pattern was gradually replacing the north-south polarization pattern in Beijing.
