中文摘要：

OFDI企业作为跨国知识管道，可为我国本土集群企业注入新的血液。从知识位势的角度出发，分析了OFDI企业和本土集群企业间的知识共享机制。通过构建中间知识位势主体积极参与和消极参与两种情况下的演化博弈模型，研究了双方的知识共享行为和相应机会主义行为的演化博弈过程。研究表明，系统的演化稳定状态是各方知识共享意愿、吸收转化能力、知识产权重视程度和知识共享的潜在风险等因素共同作用的结果。相比于中间知识位势主体的消极参与，其积极的参与行为使得系统呈现出了更加多样化的演化过程，同时也促使系统向各方均采取知识共享策略的状态演化。最后利用实证研究，验证了上述关键因素对于系统演化稳定状态的影响。

英文摘要：

As transnational channels for knowledge, OFDI corporations are capable of injecting the new blood to local enterprises in our country. This paper, from the perspective of knowledge potential, analyzes the mechanism of knowledge sharing among OFDI corporations and local cluster enterprises. The paper studies the evolutionary game process of knowledge sharing and opportunistic behavior in two cases of positive and passive participation of intermediate knowledge potential actors. It is found that the evolutionary process of the system is an emergent property resulting from interactions among willingness of knowledge sharing, absorptive capacity, emphasis on intellectual property and potential risks of knowledge sharing, etc. Agents＇ participation in the intermediate knowledge potential will promote the equilibrium of both knowledge sharing, and prompt the diversification of system evolution at the same time. Finally, the effect of key factors on end state of system is tested through a canonical correlation analysis.
