城市网络视角下的中国科技创新功能区划研究

开展科技创新功能区划是全局把握国家科技创新总体布局并指导提升区域科技创新能力极为重要的基础性工作，然而相关研究仍较滞后。本文从城市间创新合作关系网络的角度，结合已有地理区划理论和创新地理研究，设计了一种科技创新功能区划方法，基于中国357个城市间2017—2019年的专利合作关系数据，研制了一套中国科技创新功能区划方案。研究认为，将网络空间拓扑关系与地理空间位置关系相结合，借助空间邻接约束下的层次聚类与以模块度为依据的图分割技术，可以得到内部联系紧密且占据一定连续地表的区划结果，是一种科技创新功能区划的有效方法。在城市科技创新网络拓扑结构分析和二值与加权网络分区结果对比分析的基础上，研制出一套包含4个一级区和20个二级区的中国科技创新功能区划参考方案，将中国大致划分为北方、南方、东部、西部4个科技创新功能板块，每个板块包含4~6个二级功能区。这一方案的分区边界与省级行政边界具有较高的吻合性，可为国家从宏观层面进行科技创新统筹管理提供辅助参考。建议未来依托科技创新功能区的建设与区域科技创新中心的引领，因地制宜实施区域创新发展战略，更好地为国家创新驱动发展战略实施贡献力量。

Regionalization of scientific and technological innovation in China:From the perspective of urban network

Carrying out the functional regionalization of scientific and technological innovation in China is a basic work to grasp the overall configuration and guide the improvement of China's scientific and technological innovation capabilities. However, there are still large gaps in related research. Under the background of China's innovation-driven development strategy, the planning and construction of regional scientific and technological centers is considered an important task at present, which makes the functional regionalization of scientific and technological innovation in China urgently needed due to its guiding significance. From the perspective of intercity innovation cooperation network, combined with the existing geographical regionalization theories and innovation geography research, this paper devices a functional regionalization method for scientific and technological innovation in China by applying the dynamically contiguity-constrained hierarchical agglomerative clustering and the graph partitioning technology based on modularity. With the intercity patent cooperation data of 357 cities in China from 2017 to 2019 and their spatial contiguity data as an input, the topological relationship in the network space and the positional relationship in geographical space are combined to form regions covering continuous earth's surface which are tightly knit inside and show prominent regional characteristics in the scientific and technological innovation field. Based on the topological structure analysis of the urban network and the comparison between the regionalization results of the binary network and the weighted network, a regionalization scheme containing 4 first-level functional regions and 20 second-level functional regions is formulated. According to the regionalization, China is divided into four functional plates of scientific and technological innovation: north, south, east and west, each of which contains 4 to 6 secondary functional regions. The delimitation of scientific and technological innovation according to the regionalization results is highly consistent with the administrative divisions on the provincial level, providing reference for government to plan the overall management of scientific and technological innovation on macroscale. It is suggested that in the future, relying on the construction of the functional regions and the leadership of the regional central cities, all regions should formulate regional innovation and development strategies according to local conditions, and actively contribute to the implementation of the national innovation-driven development strategy.
