借鉴生命周期理论构建了基于模糊集合的产学研协同创新识别模型，从理论上将合作和协同划分为生命周期的相邻阶段，确定了协同度、合作产出、协同效应三个关键识别指标，并通过案例分析检验了识别模型的可操作性。研究结论表明：（1）产学研协同创新生命周期识别模型在保留阶段间模糊性的前提下实现了协同过程的科学划分；（2）关键指标的识别效果良好，指标量化方法能够结合主客观评价；（3）协同关系的发展路径存在差异性。

Inspired by life-cycle theory, we establish an identification model based on fuzzy set theory to theoretically divide cooperation and collaboration into adjacent stages. Three key indicators are determined, including collaboration degree, cooperation output and collaboration effectiveness. The result of from the case studies verifies the feasibility of identification model. Conclusions show that (1) the identification model on the life cycle of University-Industry collaborative innovation realizes the scientific division of collaborative process on the premise of maintaining its ambiguity; (2) the quantification of key indicators is able to be combined with subjective and objective evaluations which demonstrate good recognition effect; (3) differences exist in the development path of collaboration.
