京津冀区域创新生态系统：运行机理及效果评价

通过构建“承载-集聚-行动-产出-辐射”5个子系统和“利润回馈-技术溢出-保障机制”3个循环动力机制的区域创新生态系统，建立指标体系并运用复合系统协同度和耦合协调度模型评价京津冀创新生态系统运行水平。结果显示：2008—2018年系统运行处于低水平协同阶段，子系统有序度逐年提高，系统间耦合能力经历由低度协调向中度协调的蜕变。三地创新的马太效应、产业链与创新链耦合不足、系统间联动机制不完善是制约系统协调的短板。最后，从构建要素平衡型流动机制、强化创新链-产业链融合、优化创新生态等方面提出相应建议。

Beijing-Tianjin-Hebei Regional Innovation Ecosystem:Operational Mechanism and Comprehensive Evaluation

Build a regional innovation ecosystem with five subsystems of "bearing-gathering-action-output-radiation" and three linkage transmission mechanisms of "profit feedback-technology spillover-guarantee mechanism"，establish an index system，and evaluate the operation level of Beijing-Tianjin-Hebei innovation ecosystem by using a composite system coordination degree and coupling coordination degree model.The results show that from 2008 to 2018，the system operation is at a low level of coordination，the order degree of subsystems increases year by year，and the coupling ability between systems undergoes a transformation from low coordination to medium coordination.The Matthew effect of innovation in the three places，insufficient coupling between industrial chain and innovation chain， and imperfect linkage mechanism between systems are the short boards that restrict system coordination.Finally，some suggestions are put forward from the aspects of constructing a balanced flow mechanism of factors，strengthening the integration of "innovation chain-industrial chain" and optimizing the innovation ecology.
