中文摘要：

研究了联盟依赖和联盟冲突作为联盟稳定性的两个维度分别对伙伴知识保护的影响，并在此基础上构建了联盟稳定性、伙伴知识保护、中心企业知识获取三者之间的关系模型，提出了相关假设。运用270家中国企业的调研数据对假设进行了验证，结果发现，联盟成员企业之间的依赖和冲突都会增强联盟伙伴对于知识的保护程度，而伙伴知识保护与中心企业知识获取之间呈U型关系。研究还发现，联盟依赖能够促进中心企业的知识获取，同时对伙伴知识保护与中心企业知识获取之间的关系有正向调节作用，而联盟冲突对知识获取有显著的阻碍作用。

英文摘要：

How alliance interdependency and alliance conflict, as two dimensions of alliance stability, affect knowledge protection behavior of partner firms is focused, and a conceptual framework involving alliance stability, knowledge protection of partner firms, and knowledge acquisition of focal firms is built. Six hypotheses are proposed and tested based on the survey data of 270 Chinese firms. The empirical results show that both alliance interdependency and alliance conflict reinforce the knowledge protec- tion of partner firms, and there is a U - shaped relationship between knowledge protection of partner firms and knowledge acquisi- tion of fecal firms. It is also found that alliance interdependency facilitates the knowledge acquisition of focal firms, and positively moderates the U - shaped relationship between knowledge protection of partner firms and knowledge acquisition of focal firms, whereas, alliance conflicts have a negative effect on the knowledge acquisition of fecal firms.
