Research on the object business selection for corporate diversification based on grey correlation theory

In this study, an analytical framework of the object business selection for corporate diversification is established based on the theory of grey correlation. And the resource dependency for corporate diversification is analyzed by combining fuzzy comprehensive evaluation with grey multi-hierarchal synthetic evaluation model. In addition, the calculation model of synergistic degree is built to verify the gray correlation. The result shows that the grey correlation between surplus resources possessed or needed by the corporations and the resources needed or possessed by the object business are positively correlating. It will improve the synergistic effect and finally increase the successful rate when the corporations select the object business in which the resources have the high grey correlation with the surplus resources possessed or needed by corporations themselves.
