Abstract:The emerging new technology changes the structure of traditional manufacturing industry, and makes the incumbent firms to transit and finally reconstruct the business ecosystem. Hence, the case of Haier Group was chosen together with the perspective of resource dependence theory, trying to answer the research question: how does the traditional manufacturing firms’ transition affect the changes of membership, dependence relations and functions in business ecosystem? The results show that: external environmental changes lead the strategic change of a firm; firms would take several strategies to reduce the power control of resources owners; integration of internal and external resources generates new competence and competitive advantage; the changes of resources dependence relations lead to the business ecosystem reconstruction in terms of membership, dependence relations and functions.
