Focusing on the current situation of supplier relationship recognition by qualitative analysis method, with supply characteristics of automobile components industry, a two dimensional quantitative supplier relationship recognition model for automobile components industry is established in this paper. Supply relationships are recognized quantitatively from relationship type dimension and relationship life cycle dimension. Supplier relationship is divided into three types:, which are partnership, general supply and temporary purchase relationships. Fisher Discriminant Analysis is used to recognize the types quantitatively and the recognition indicators include value ratio, quantitative proportion, the rate of timely arrival and the number of potential suppliers. The relationship life cycle is divided into four stage, which are exploring period, development period, maturation period and declining period, and its quantitative recognition indicator is Trade Development Index (TDI). Case analysis shows that the proposed model and indicators could recognize state and its changes of supplier relationship effectively.
