城市创新联系的研究对揭示创新空间结构特征、制定区域创新发展策略具有重要意义。本文运用空间相互作用模型对广东省2003、2012年21个地级城市的创新联系空间格局进行测度,分析空间格局演变的特征,并探讨广东省创新联系空间格局的发展与优化策略。结果表明：广东省城市创新联系的空间格局呈现新型“核心—边缘”结构,珠三角仍是这一结构的核心,但有弱化和分化趋势;区域整体网络化程度增强,珠三角外围地区有反极化趋势出现。2003-2012年,创新中心城市由5个变为6个,其辐射范围大小及方向发生变化,辐射强度仍维持强强联合的格局。未来应促进现有创新联系空间格局的优化,在区域整体层面上形成多中心网络化的创新结构。

英文摘要：

Research on innovation linkages of cities has an important significance for revealing characteristics of innovative spatial structure and forming strategies for regional innovation development. This article uses a spatial interaction model to measure the spatial structure of innovation linkages among 21 cities in Guangdong Province in 2003 and 2012, with the aim to reveal the change of the spatial structure. Strategies tbr the development and optimization of spatial structure of innovation linkages in Guangdong Province are discussed based on data analysis and principles of urban spatial organization. The article concludes that the spatial structure of innovation linkages in Guangdong province shows a new ＂core-periphery＂ structure and the Pearl River Delta cities are at the core of this structure, which shows a weakening and differentiation trend compared to the past. The overall degree of network linkage is enhanced, and there is a tendency of anti-polarization in periphery regions of the Pearl River Delta. From 2003 to 2012, the number of innovation center cities dropped from 6 to 5. Both radiation range and direction of innovation center cities experienced some changes, and innovative radiation intensity showed a ＂strong-strong combination＂ pattern. In the future, the existing spatial pattern of innovation linkages should be optimized and regional polycentric network innovative pattern should be built on the regional scale.
