Study On The Market Adaptability Of Railway Bulk Freight Rate Based On Coupling Coordination Degree

As the main adjustment lever of railway transportation industry,the rationality of its application is directly related to the operating efficiency and development prospect of railway transportation enterprises.As an important transportation object of railway,the freight rate of bulk cargo is particularly important.Under the condition of market economy,it is very necessary to deeply analyze the factors that influence the formation of railway bulk freight rate in China,so as to promote the rapid development of railway bulk freight transportation in China.At present,the freight rates of various modes of transportation are changeable and gradually from market-oriented transportation prices,which satisfy the needs of customers.Therefore,this paper starts from the current situation and characteristics of railway bulk freight rate,and analyzes the law of coupled and coordinated development of railway bulk freight rate market by means of qualitative and quantitative analysis.At the same time,the market adaptability of railway bulk freight rates is interrelated and interactive,and their coordinated development plays an extremely important role in the sustainable and healthy development of China’s economy.However,in real life,they are often in an uncoordinated state,which restricts the development of railway freight transportation.Therefore,this paper establishes the coupling coordination degree model from the coupling coordination angle of the market adaptability of the railway bulk freight,and use coupling theory and coordination theory as the theoretical basis of this paper to establish corresponding evaluation index system from four aspects: cost factor,demand factor,supply factor and substitution factor.Based on the evaluation index system,this paper constructs the coupling coordination degree model of railway bulk freight market adaptability,and verifies and analyzes the coupling coordination degree of China’s railway bulk freight market adaptability in four factors according to the coupling coordination degree model,which provides a new idea and method for studying the railway bulk freight market adaptability.There are 15 figures,17 tables and 66 references.
