中文摘要：

摘要：本文以中国大陆31个省区为研究单元，通过构建综合评价指标体系。运用空间局部自相关、柯布一道格拉斯生产函数、耦合协调度模型等方法，对2002--2014年科技创新能力空间演变及其与经济发展之间的关系进行分析。结果显示：①科技创新能力及其各组成要素整体呈现上升趋势；②各省域科技创新能力水平由低层次水平逐渐向高层次水平演变．东部沿海和长江沿线部分省区科技创新能力较强，西北和西南两大片及中部少数省区科技创新能力较为薄弱；③大多省域科技创新能力在空间关联演变上呈现路径依赖与锁定特征：④科技创新对经济发展的推动作用明显提升．科技创新与经济发展的关系跨越了从失调衰退到优质协调的七个阶段类型，各省区都形成了关系类型的阶段提升，空间梯度格局明显。

英文摘要：

The paper used 31 provinces as research area. It analyzed the provincial scientific and technological innovation ability by constructing a comprehensive evaluation index system, and used the local spatial autocorrelation, Cobb-Douglas production function to analyze spatial evolution of scientific and technological innovation ability and the types of relationship with the economic develop- ment. The results show that： China innovation ability showed upward trend from 2002 to 2014; Innovation ability level gradually evolved from low level to high level; The eastern coastal areas and some provinces along the Yangtze River have high innovation ability. Areas of low level ability evolution are concentrated in the northwest and southwest regions; The evolution of spatial pattern of China＇s scientific and technological innovation ability has a locking characteristics and path dependence; Innovation ability has promoted economic development; The relationship between innovation and economic development across from recession to high quality coordinated, various provinces have formed a relationship type order and the gradient pattern is obvious.
