摘　　要：以中国31个省市自治区为研究单元,以R＆D强度为测度指标,采用传统统计分析方法,结合马尔可夫链和ESDA,分析了2001~2011年中国R＆D投入的区域差异及时空格局演变。结果表明：中国省域R＆D投入的绝对差距在扩大而相对差距在缩小,空间相关性逐渐增强,存在明显的＂俱乐部趋同＂现象。东西部之间R＆D投入的空间差异有所扩大并呈两极分化的态势,投入重心正在向东南部偏移。R＆D投入增长也具有明显的空间集聚特征,并形成了以长三角和鲁皖赣为核心向中西部地区梯度推进的圈层结构。增长热点区由分散格局转为集中连片格局,增长冷点区在大幅减少,全部集中在西部地区。R＆D投入时空差异的形成受经济发展水平、政府科技投入力度、产业结构的变化和人力资本积累等多个因素的影响。This paper analyzed the regional disparities and spatial-temporal evolution of China＇s R＆D investment during 2001-2011 based on the 31 provincial units. The research employed R＆D intensity as the major measuring index, and used other methods such as traditional Statistic analysis, Markov chains and ESDA. The result shows as follows. （1）The absolute disparity of China＇s provincial R＆D investment had widened while the comparative disparity had narrowed. China＇s provincial R＆D investment had shown a significant feature of spatial autocorrelation since 2006. The areas with similar features clustered in space, and the trend was strengthening except in 2009, indicating that the overall space difference was narrowing. There was a remarkable phenomenon of ＂Club Convergence＂, and the transition probability between different clubs was small. （2）Concerning to the overall spatial framework, Zhejiang and Shandong provinces in the eastern coastal area were experiencing club upward mobility, Shanxi and Sichuan in the western area and Liaoning and in the Jilin northeast area were at club downward mobility. Areas with high R＆D investment were transforming from a scattered pattern to concentrated in the southeastern coastal area, especially on Beijing and Shanghai. In contrast, areas with low R＆D investment were more and more concentrated in the central, western and northeast areas. In general, the spatial disparity of R＆D investment had been enlarging between the eastern and western area, and manifested an obvious tendency of polarization. （4） The spatial pattern of the growth of R＆D investment also showed a strong trend of spatial autocorrelation, and formed the layer structure circling around Yangtze River Delta and Shandong-Anhui-Jiangxi towards the Middle and West area. The hot spot areas used to be scattered around the Beijing-Tianjin city-region and Pan-Yangtze River Delta. However, it is now concentrated in Yangtze River Delta and spreading outwards. The numbers of the sub-hot spot are
