According to the research object and core, the competitory power of bio-industry, this thesis was unfolded from four aspects: Firstly, we put forward the competitory power of bio-industry theory, its concepts and categories, analytical frame and theories structure from analyzing its influence and determinant system; Secondly, appraisal models, based on deciding factors, composing factors and realizing factors, were respectively established, by using related mathematics method, cooperate theories, management and economics theories; Thirdly, according to the research on life cycle of bio-industry, we analyzed the characteristics and countermeasures of its competitory power changing at different stages; Fourthly, we focused on the core carrier of the bio-industry andits competitory power--the bio-industry cluster (life science industry park and biologicvalley), the bio-industry cluster theories and the park-area competitive factors and the capital market and the financing competition which are important drive factors of the competitory power of bio-industry. Firthly, making use of the evaluation model of bioindustrial competition ability, we carry on bioindustrial competition ability comparison of the United States and Chinas, and evaluate a substantial evidence.
