Abstract: Industry convergence causes the value chain of different industries to be deconstructed and reorganized, and the modes and its ability of value-added are also changed. This paper starts from the interactive convergence of different types of industries: convergence among traditional industries, convergence between traditional industries and emerging industries, convergence among emerging industries. It explores the transition of core value area of the three models after certain convergence among industries respectively and comparatively. This study reveals that the industrial value can transfer or increase after convergence, and will differ under various convergence models. The conclusion might complement the future study of industry convergence theory and regional value chain theory.
