| The main modes of transportation include inland river shipping,road transportation and railway transportation.For a long time,inland river shipping is an important part of transportation industry.The upper reaches of the Yangtze river is an important waterway connecting the east and the west.With the obvious achievements in the construction of the upper reaches of the Yangtze river waterway,the proportion of goods transported by the waterway in the upper reaches of the Yangtze river is also increasing,which is related to the economic development of the upper reaches of the Yangtze river.This paper analyzes the current situation of transportation in the upper reaches of the Yangtze river,and summarizes the basic characteristics of three kinds of transportation.Each of the three modes of transportation has its own unique advantages and disadvantages in different aspects,which makes them different in their attraction to the transportation of goods.The attraction of the three modes of transportation to the transportation of goods,from another point of view,can be understood as the distribution of goods in the three modes of transportation.To study the competition between shipping and public railway transportation is to study the choice of three transportation modes.Based on a detailed study of the choice between several alternatives by decision-makers at home and abroad,this paper finds that the competition between shipping and public railway transportation in the upper reaches of the Yangtze river is also a kind of decision making problem,and the choice of transportation mode by cargo shippers is related to the nature of the three transportation modes and the nature of the cargo itself.This paper firstly analyzes and determines the factors that affect the competition between the upper reaches of the Yangtze river shipping and public railway transportation,and selects three factors,namely transportation cost,transportation distance and cargo weight,as the factors that affect the probability of choosing three transportation modes.Then,multiple discrete selection was used to establish a discrete model of competition between the upper reaches of the Yangtze river shipping and public railway transportation,and the mnrfit function and mnrvalmnrfit function programming provided by MATLAB were used to carry outLogistic regression.First,the natural logarithm expression of probability ratio was obtained by using the function mnrfit,and then the mnrval function was used to predict the percentage of cargo choosing the hydro-rail highway after the waterway was improved.This paper explains the influence of three factors on competition,and finally predicts the distribution of goods in three modes of transportation.The method used in this paper effectively takes into account the factors of the competition between traveling shipping and public railway transportation,and can more reasonably predict the distribution proportion of goods in different transportation modes after waterway elevation,so as to calculate the waterway freight volume induced by waterway elevation,which also has certain guiding significance for waterway construction.At the end of this paper,the conclusion and technology are summarized and prospected. |
