Client's decision-making behavior and redistribution of freight flow in affiliated market

According to the hypothesis that client is rational decision-maker in classic decision theory, the generalized circulating cost model and generalized purchasing cost model of freight, the affiliated degree model among different transportation modes and the sensitive model of generalized purchasing cost relative to transportation price and transportation time were build, and the properties and influence factors of client's decision-making behavior and the redistribution of freight flow were analyzed in affiliated freight market. It is pointed that different modes might produce different generalized circulating transport costs aimed at the same amount freight, client chooses transport model according to generalized circulating cost; when the affiliated degree between two kinds of transportation modes is close to 1, competition increasingly becomes fierce in affiliated freight market; the elasticity coefficients of generalized purchasing cost relative to transportation price and transportation time respectively equal to the ratios of the transport fee and on-way time cost of freight to generalized purchasing cost, the time cost of goods relatively remains stable, so the decision-making behavior of client and the distribution of freight flow are decided by goods attribute and transport technique.
