摘　　要：长江三角洲地区自1978年以来经济的快速发展推动着区域经济格局的演变。采用1978-2005年长江三角洲16市GDP数据,首先计算分析区域GDP增加的总量与速度,定量描述区域经济的不平衡性,进而引入区域重心的概念,定量表示出长江三角洲地区改革开放以来GDP重心的动态演化过程。结果表明:长江三角洲地区GDP增长速度较高的城市主要沿宁沪杭甬铁路呈"Z"型分布;发展速度较低的主要分布在长江三角洲边缘及两翼地区;上海市与第二位城市的差距有所减小;区域GDP重心整体上表现出缓慢、定向的向西南移动趋势,表明区域差异总体上在不断缩小。It is well known that the regions of Yangtze River Delta are always the one of biggest economic region of China, spatial pattern of regional economy has been influenced by the development of these regions. Studying on the spatial distribution and evolutional process of regional economy, it can help us understand the spatial transferring characteristics, their changes and development trend of regional economy more accurately, and this also can be of great significance for developing the strategy for regions of Yangtze River Delta scientifically and rationally. Based on the data of the GDP during 1978 and 2005, the paper figures out the quantity and speed of GDP, it quantitatively analyzes spatial disparity of regional economy and introduces the concept of center gravity, expressing developing evolvement of GDP center of gravity. The result indicates that the regions with higher growth rate of GDP are mainly distributed by the railways linked Nanjing, Shanghai, Hangzhou with Ningbo; it takes the shape of＂Z＂, the lower regions are mainly distributed in the edge of the Yangtze River Delta. The disparity between Shanghai and the second city has reduced to some extent. The GDP gravity center slowly moves to south-east in Yangtze River Delta in Post- Reform and spatial disparity has a tendency to balance,
