摘　　要： 基于创新价值链视角,将我国创新活动分为知识创新、科研创新、产品转化创新三个阶段,研究其区域空间格局及其演化特征。研究表明:(1)从平均增长率看,知识创新产出低于科研创新和产品转化创新。(2)科研创新活动存在显著的空间集中性和空间相关性,表现出稳定的增长趋势,但收敛性不明显;知识创新活动趋同迹象鲜明且收敛性明显;产品转化创新活动的空间集中性呈稳定下降趋势,不存在空间相关性和收敛现象。(3)我国逐渐形成了以上海为中心的科研创新高水平区域集聚格局,而西北地区在整个创新价值链环节均显现出低水平集聚的格局,创新活动的地域性特征十分鲜明。 Based on the perspective of innovation value chain, we divide the innovation activity into three stages ： knowledge innovation, research and development innovation and product transformation innovation, studying the spatial pattern and temporal evolution of each stageJ s innovation activities. The results indicate that ： firsdy, the average growth rate on knowledge innovation output is lower than that of the research and development innovation and product transfoimation innovation ; secondly, spa-tial concentration and correlation are significant and have steady growth trend for research and devel-opment innovation, but convergence is not significant; knowledge innovation activities have signs of convergence and its convergence is obvious ; There exists a steady decline in spatial concentration for product transformation innovation, and they have neither spatial concentration nor convergence ; Third-ly ,China gradually forms a pattern of high - level regional innovation cluster centered on Shanghai, while the north - western districts form a low level of innovation cluster pattern through the entire in-novation value chain, which indicates that the regional characteristics of Chinese provincial innovation activities is pronounced.
