An evidence-based acquisition study based on a trilateral evolutionary game

Abstract: Purpose/Significance High-quality collection development is the basis of libraryservices. and the current mainstream acquisition models. such as big deal and patron-decisionacquisition, have certain defects. This paper focuses on the new emerging acquisition model-evidence-based-acquisition, and investigates the influence among its related players to promotethe development of evidence-based acquisition. (Method/Process This paper constructs aripartite evolutionary game model of libraries. users. and resource providers by sorting outevidence-based acquisition. analyzing its replication dynamic equations as well as evolutionarstabilization strategies and simulating them through MATLAB. Then it dissects the impact ofdifferent parameters on facilitating the evolution of evidence-based acquisition, clarify theunteraction and association of their related objects. and gain insight into the dynamics of evidenceased acquisition. Result/Conclusion  The model has two evolutionary stabilization strategiesand suggestions are made for the development of evidence-based acquisition by combining thegame results with the actual situation.
