京津冀区域吸收能力的测算和空间协同研究

Study on the Measurement and Spatial Coordination of the Regional Absorptive Capacities in Beijing-Tianjin-Hebei

以双向专利权转移流为切入点，使用空间交互模型估计目的地固定效应，测算出区域吸收能力并探索京津冀区域协同创新中“疏得出、接得住、能发展”的空间协同模式，对协同创新中“谁来协同，往哪协同，怎么协同”等关键问题进行突破。研究发现：①京津冀协同创新的网络结构呈现“核心-半核心-边缘”特征，北京、天津、石家庄和唐山等现实吸收能力较强的地区应成为协同主体。②根据技术同质性和空间相邻性对现实吸收能力的重要作用，测算出京津冀区域的有效吸收半径为200～300km，潜在区域吸收能力呈现中部、东部和东北部较高的特点。③根据现实和潜在吸收能力的适配后总结出四种空间模式。与《京津冀协同规划纲要》的最新空间布局相比，还需从当前的圈层状吸收格局向版块状发展，加强京津、京保石、京唐秦的结点连接，提升廊坊、保定、秦皇岛、承德的潜在吸收能力。

From the perspective of bilateral patent transfer, this paper uses a spatial interaction model to estimate the destinations＇ fixed effects and measure Beijing-Tianjin-Hebei＇ s regional absorptive capacities. It explores the spatial coordination pattern of the abilities in dispersal, undertaking in the regional coordinated innovation,to find a breakthrough for the problem of ＂who, where and how to coordinate＂. 1）For whom to be coordinated： the network structure of Beijing- Tianjin-Hebei＇ s regional coordinated innovation shows the feature of ＂core→semi-core→ border＂, so that Beijing, Tianjin, Shijiazhuang and Tangshan which have stronger real absorptive capacities should be the principal cities for coordination. 2）Where to coordinate： it verifies the essential effects of technological similarity and spatial proximity on real absorptive capacities and estimates that the valid radius is between 200km to 300km. The potential regional absorptive capacity are higher in the middle, eastern and northeastern part. 3）How to coordinate： It adapts the potential and real capacities to conclude four types of spatial pattern. Compared to the spatial arrangement in the plan for coordinated development, the absorptive pattern should be development from circles to blocks. The connection between Beijing- Tianjin, Beijing- Baoding- Shij iazhuang and Beijing- Tangshan- Qinhuangdao should be strengthened to upgrade the potential absorptive capacities in Langfang, Baoding, Qinhuangdao and Chengde.
