在知识经济时代，合作创新成为企业重要的战略选择。吸收能力是创新最关键的因素，也是研究合作创新的切入点。但吸收能力的现有研究因忽视组织间关系而使其难以对合作创新进行深入认识。本文以组织间对偶关系为基础，将关系维度引入吸收能力的经典概念，提出关系性吸收能力。本文通过建模与仿真展示了合作创新的机理与过程，揭示了关系性吸收能力对合作创新的关键作用，并基于吸收能力进一步探讨了实现合作创新的驱动机制与保障机制。  

Cooperative innovation is the most important strategic choicefor enterprises in the knowledgeeconomy. As the critical factor for innovation, the Absorptive Capacity (AC) serves a point of penetration for the researches of cooperative innovation. The present literatures about AC ignore the inter-organizationalrelationships and limit the further exploration of cooperative innovation. The relational dimension is added into the classical concept of AC and enhanced it into the dyadic relationship based AC-Relational Absorptive Capacity (RAC) . Through model and simulation of the innovation process, the critical role of RAC in cooperative innovation is revealed, and further more, the driving and supporting mechanisms for the realization of cooperative innovation are explored. . 20 Refs In Chinese
