The existing e-commerce strategic researches have many problems in practical application. Based on AHP and fuzzy evaluation, the paper studies strategic programming evaluation of vertical industry B2B E-commerce, establishes strategic ambiguity evaluation model of vertical industry B2B e-commerce company, selects the best strategic program from the altennative strategic programs, and makes empirical analysis. Lastly, based on summarizing the thesis, the paper proposes suggestions and prospection for the study in the future.展开更多
