产学研合作中，科技投入和研发质量是影响创新发展的核心要素。在政策框架和市场环境下，创新投入主体与研发主体通过合作获得研发成果，并通过成果的价值获得收益，双方群体在不完全信息条件下形成动态博弈的系统。为研究如何促进科技投入和研发质量提升，本文通过演化博弈方法对科技投入与创新质量进行建模分析，研究科技创新体系中投入主体与研发主体博弈中的策略选择机制、投入与质量之间的相互影响和主要因素，探索通过管理改进提升创新活力和水平的途径。通过模型分析，推论出改善收益和奖励机制、优化创新环境、提升创新价值对产学研合作的良性发展至关重要，并提出政策建议。

In the cooperation between industry, University and research institutes, the input of science and technology and the quality of R&D are the key factors affecting the development of innovation. Under the policy framework and market environment, the subject of innovation investment and the subject of R&D obtain innovation outcome through cooperation, and gain benefits through the value of the results. Under the condition of incomplete information, the two groups form a dynamic game system. In order to study how to promote investment in science and technology and improve the quality of R&D, this paper uses evolutionary game theory to model and analyze the investment and innovation quality of science and technology, studies the mechanism of strategy selection, the interaction between investment and quality, and the main factors in the game between the input and R&D subjects in the system of science and technology innovation, and explores the ways to improve the innovation vitality and level through management improvement. Through the model analysis, it is concluded that improving the income and reward mechanism, optimizing the innovation environment and enhancing the value of innovation are essential to the healthy development of University-Research cooperation, and policy recommendations are put forward.
