Abstract: Abstract: Strategy entrepreneurship theory emphasizes on independent innovation and new product development, based on the strategic management of resource, but it lacks some explanation for the implementation procedure and the inside driving force of the strategic entrepreneurial behavior. Besides, its objects are those enterprises with advanced technology in developed country, thus it has little guidance for these OEM companies in developing countries to get rid of path dependence and realize the technology and brand upgrading. To solve this problem, this study made an exploratory research on the transition and upgrading path of BYD, about how it developed into OBM from OEM. The result shows that, through establishing net relationship, imitation learning, innovation investment, and international behavior, OEM can realize strategic entrepreneurship, and promote its transition and upgrading.Meanwhile, this study also reveals that, the entrepreneurs’ innovative conception and opportunity perception ability are the driving force of strategic entrepreneurship. Moreover, the innovation oriented culture of down-to-earth and people oriented, can promote the transition and upgrading process of OEM.

摘要： 摘要：战略创业理论强调资源战略管理基础上的自主创新与新产品研发，对战略创业行为的实现过程与内在驱动力解释不足。并且它的研究对象是发达国家的技术先进企业，对发展中国家代工企业如何突破路径依赖以及实现技术与品牌升级指导作用有限。为解决此问题，本文对比亚迪公司从OEM到OBM的转型升级路径作了探索性研究。结果显示，代工企业可以通过网络关系构建、模仿学习、创新投入以及国际化行为，实现战略创业，推动代工企业的转型升级。同时还发现，企业家创新理念与机会感知能力是代工企业实施战略创业行为的内在驱动力，而“脚踏实地、以人为本”的企业文化强化调节了代工企业从OEM到OBM的转型升级过程。
