【摘要】 [目的/意义]以图书馆新兴资源采购模式——循证采购为中心，研究其相关主体之间的演化博弈模型，促进循证采购的发展。[方法/过程]通过对循证采购的梳理，构建图书馆、用户、资源商三方演化博弈模型，分析其复制动态方程与演化稳定策略并通过MATLAB进行仿真模拟，剖析不同参数对促进循证采购演化的影响，厘清其相关对象的交互关系和关联关系，洞悉循证采购的动力。[结果/结论 ]该模型存在两个演化稳定策略，结合博弈结果与实际情况对循证采购的发展提出建议。更多还原

【Abstract】 [Purpose/Significance] This paper focuses on the new emerging resource acquisition model of library——evidence-based acquisition, and investigates the evolutionary game model among its related players to promote the development of evidence-based acquisition. [Method/Process] This paper constructed a tripartite evolutionary game model of libraries, users, and resource providers by sorting out evidence-based acquisition, analyzing its replication dynamic equations as well as evolutionary stabilization strategies and simulating them through MATLAB. Then it dissected the impact of different parameters on facilitating the evolution of evidence-based acquisition, clarified the interaction and association of their related objects, and gained insight into the dynamics of evidence-based acquisition. [Result/Conclusion] The model has two evolutionary stabilization strategies, and suggestions are made for the development of evidence-based acquisition by combining the game results with the actual situation.更多还原
