Abstract: This paper is determined to explore the relationship between knowledge division, knowledge synergy and innovation performance including technical effect and scale effect. Various data sources including R&D inputs and innovation results during 2000-2014 of University, research institutes and enterprises, are used to measure the innovation performance by the method of DEA, to make an empirical study by the model of tobit. It has been found that: (1)knowledge division is positively related to the technical effect, negatively correlated with the scale effect, and exhibit a reverse “U” relationship with the innovation performance;(2) knowledge synergy, technology effect, scale effect and innovation performance are positively correlated;(3) knowledge synergy can enhance the positive marginal contribution of knowledge division to the technology effect, and reduce the negative marginal contribution of knowledge division to the scale effect, which makes the marginal contribution of knowledge division to innovation performance increasing.

摘要： 产学研协同创新的绩效可分为技术效应和规模效应。文章在探讨知识分工、知识协同与产学研创新的技术效应、规模效应与创新绩效关系的基础上，利用2000-2014年间的大学、科研院所及企业研发投入及创新成果的数据，通过DEA对产学研协同创新的技术效应、规模效应及创新绩效进行测算，利用Tobit模型进行实证。研究表明：知识分工与技术效应正相关，与规模效应负相关，与创新绩效呈倒U型关系；知识协同与技术效应、规模效应与创新绩效正相关；知识协同能够提升知识分工对技术效应正的边际贡献、降低知识分工对规模效应负的边际贡献，使得知识分工对创新绩效的边际贡献递增。
