Abstract: Industry Technology Innovation Strategic Alliance(ITISA) springs up and becomes the main force of innovation in China. This paper examines the impact of organizational complexity and type of lead institutions on the cooperative innovation frequency of ITISA employing the event history analysis method. Using a sample of 205 cooperative events in 37 ITISAs, we find that: 1) there is inverse “U” relationship between organizational complexity and cooperative innovation frequency; 2) industry association taking the lead institution can promote frequency of knowledge sharing, and university or research institute taking the lead institution can promote frequency of technological cooperation; 3) the policies about ITISA reduce the cooperative innovation frequency. Thus, ITISA should optimize organizational size and structure, and elect lead institution according function. Government should make strategic planning about development of ITISA, and related polices. 

摘要： 产业技术创新战略联盟（简称产业联盟）在我国大量涌现，成为实现创新驱动发展的中坚力量，其组织特征却困扰着长效合作机制的建立。本文基于37家产业联盟的205项合作创新事件数据，采用事件史分析方法，对组织复杂度、牵头单位类型等因素与合作创新率之间的关系进行实证研究，结果表明：1）组织复杂度与产业联盟的合作创新率之间存在倒“U”型关系；2）行业协会任牵头的产业联盟具有更高知识共享率，高校/科研机构牵头的产业联盟具有更高的技术合作率；3）现行的鼓励性政策反而降低了合作创新率。根据上述结论，产业联盟自身应当优化规模与结构、依据功能选择牵头单位，政府则应加强战略规划、完善产业联盟组建和发展的相关政策。
