Research & Application On Demand, Supply And Equilibrium Of Correlative Freight Transport Market

In recent years, with the transport coming into market to a higher extent and the competition growing more heated, the analysis of economic theory of transport marketization becomes a new subject in the field of transport economy in nowadays.In this dissertation, the main studies is the correlative market equilibrium theory, it comprises the structure of freight transport market, the market behavior, and the evaluation of market effective. When different modes of transport contest the same demand segmenting market, they are named as correlative ones in the market, and their equilibrium as correlative equilibrium. The study of correlative equilibrium theory breaks through the much forced hypothetical conditions under which the market behavior in a single transport mode is studied.Based on the hypothesis that selecting of freight transport demand is a rational one, one fixed mode of freight transport demand is built up in this dissertation to the standard of wide circulation coat, escaping the difficulty of the measurelessness of utility. Meanwhile, the proportion of the sum of freight transport cost and time value to the total cost of wide purchase decides the goods-owner's sensitivity to the transport tariff and the level of services. Therefore, by summing the problem of transport mode selecting up as a structural decision problem, the electing of freight transport mode among the relative ones, the cross price elasticity model and the cross service elasticity model are all based on the technologic and economic property of transport and the natural characteristics of goods itself.By using the production organization of railway transport as the original model, transport product cost function and transport product supply function are also built in this dissertation according to the feature of the network, and an explicit model of economic property of scale and scope is obtained. The cost function of transport product between two adjacent points in a network is the foundation of the cost evaluation of two random points in this network. It is also the base for transport merchants to choose the operational network pattern and thus the basic theory for the study of their marketbehavior. The study also shows that, due to the derivative property of transport demand, even though there exists the economic property of scope, when the network demand to be expanded is insufficient, even expanding scope can make the total income increase, the feature that the fixed cost rises up step by step will cause the efficiency level to decrease. The equilibrium of transport market in which there exist two or more relative transport modes is studied. The analysis of the equilibrium processing of such relative markets as railway-highway, railway-highway-waterway under the two kinds of condition that railway tariff is regulated or not shows that, relative market structure is mainly decided by the most perfect match between the technologic and economic properties of relative transport modes and the tendency of the sensitivity to this segmenting market; therefore, in the terms of the market structure of that kind of transport mode, which is of relative superiority in competition, the relationship will improve the degree of market competition; the equilibrium price is the result of the competition among various transport modes; a model of measuring the degree of market relationship is built on the wide circulation cost structure; the elasticity of wide purchase total cost to transport cost and that to on-way time cost are the basic factors that respectively decide the goods-owner's sensitivity to transport price and to transport services level; when regulated price is higher than relative equilibrium price, it will make railway enterprises lose competence in the transport market and become inefficient in their resources. On the contrary, it will produce corrupt behavior or cause a kind of borderline organization.Researching on relative market structure and market behavior also shows that whether the industrial property of transportation, especiall...
