产业创新行为对产业空间关联的作用

理论上，产业创新行为是促进产业资源整合和产业关联的动力来源。基于2002—2017年规模以上工业数据，就京津冀产业创新行为对产业空间关联的作用关系进行比较分析。研究结果表明：天津、保定、沧州等地的产业中心地位正在加强，北京和石家庄的产业中心地位在下降；自主创新行为作为产业结构优化升级的内生力量对京津冀产业关联的影响具有普遍性和一般性；开放创新行为对京津冀产业关联的作用具有关系异质性和特殊性。因此，需要根据京津冀产业关联网络的现实特征，在建设“北京研究—天津开发—河北应用”创新链的基础上，充分发挥各地优势，联合开展产业创新活动，促进产业的有效联系和要素整合。

Research on the Role of Industrial Innovation Behavior on Spatial Correlation

Theoretically, Industrial innovation behavior is the impetus source of industrial resource integration and industry association. Based on energy-scale industrial data from 2002 to 2017, this paper makes a comparative analysis of the relationship between industrial innovation behavior and spatial correlation in Beijing-Tianjin-Hebei. The results of the study show that the industrial center status of Tianjin, Baoding and Cangzhou is strengthening, and the industrial center status of Beijing and Shijiazhuang continues to decline. Independent innovation, as an endogenous force of industrial structure optimization and upgrading, has universal and general influence on industrial linkage of Beijing-Tianjin-Hebei. The role of open innovation in industrial linkage of Beijing-Tianjin-Hebei has relationship heterogeneity and particularity. Therefore, according to the actual characteristics of the industrial linkage network of Beijing-Tianjin-Hebei and on the basis of building the innovation chain of "Beijing research - Tianjin development - Hebei application", we should give full play to the advantages of various regions and jointly carry out industrial innovation activities to promote the effective link and the integration of elements of industry.
