By decomposing complex issues into factors at all levels, Grey Relativity Analysis (GRA) can effectively calculate the degree the main factors affect the goal value, and overcome the problems that the traditional mathematical statistics have such as big samples, heavy computation, and inconsistency between quantitative results and qualitative analysis. So it becomes one kind of simple, convenient and distinctive systematic analysis method. GRA is applied to corporate crisis early warning analysis. The paper through the GRA the half of this quantitative approach, explores the correlation degree among the corporate crisis early warning factors, in order to find the importance sequence of instance enterprise early warning crisis factors by calculation so as to provide a theoretical foundation for the prevention and decrease of the instance enterprise crisis. 展开更多
