创新共同体是加强城市群空间尺度上协同、推动区域经济高质量发展的重要举措。本文基于创新共同体跨区域协同和溢出效应等特征，引入了空间因素和地方保护主义行为，构建了协同视阈下长三角创新共同体演化博弈模型，以案例仿真刻画动态演化过程和重要影响因素。研究表明：政府介入对创新共同体建设发挥重要作用，知识产权保护、政府支持等因素对系统趋于协同创新方向演化具有正向作用，力度越大，系统收敛速度越快；地方保护主义和空间距离对系统向协同创新演化有负向作用，超过一定阈值后，难以结成创新共同体；学研方的学术质量对系统趋于协同创新方向演进具有正向作用，学术质量越高，系统收敛速度越快；企业和学研方的努力程度存在一定最优区间，区间内可促使博弈方向协同创新演进。本研究结论对全面认识创新共同体建设与演化，推动区域间良性互动，实现区域经济高质量发展具有重要现实意义。

Innovation community is an important measure to strengthen the urban agglomeration spatial coordination and promote the regional economy high-quality development. Based on innovation community characteristics of cross regional synergy and spillover effect, this paper adds spatial factors and local protectionism, constructs the innovation community evolutionary game model in the Yangtze River Delta from the synergy perspective, and uses case simulation to describe the dynamic evolution process and important influencing factors. The research shows that: Government intervention plays an important role in innovation community. Factors such as intellectual property protection and government support have a positive effect on system evolution in the direction of collaborative innovation. The greater the strength, the faster the convergence speed of the system; local protectionism and spatial distance have a negative effect on the system evolution to collaborative innovation. When it exceeds a certain threshold, it is difficult to form a community; The academic quality has a positive effect on the evolution of the system towards collaborative innovation; There is an optimal range for the enterprises and researchers efforts, which can promote the collaborative innovation evolution in game direction. The conclusion has important practical significance for a comprehensive understanding of the innovation community construction and evolution, promoting the benign interaction between regions and realizing regional economy high-quality development.
