Research On Optimal Allocation Of Factors In Transportation Industry Based On Input-output Analysis

Under the condition of limited resources,use limited resources to better meet social needs,obtain maximum benefits,promote the construction of modern transportation systems,improve transportation’s contribution to economic and social development,rationally allocate resources,and optimize transportation structures.The realization of the complementary advantages of various modes of transportation is a key issue for my country to become a powerful country in transportation.Measuring the contribution of the transportation industry to the economic system and optimizing and adjusting the input of transportation industry elements is a necessary prerequisite for accurately grasping the position of the transportation industry in the economic system,balancing transportation demand and supply,rationally allocating resources,and scientifically adjusting the transportation structure.Therefore,based on the input-output method,this article studies the optimization of the transportation industry’s factor allocation.First of all,this article sorts out the relevant literature on the economic contribution of the transportation industry and the optimization of factor allocation,summarizes and draws on the excellent research results among them,and clarifies the relevant research theories.Secondly,on the basis of summarizing the research results of the predecessors,according to the actual research situation of this paper,a research model for the measurement of transportation economic contribution and the optimization of factor allocation is constructed.Third,use the input-output method to quantitatively measure the economic contribution of the four transportation modes of my country and Beijing from 2007 to 2018 by railway,road,waterway,and air transportation,and evaluate the impact of the four transportation methods on the economic system.The depreciation of fixed assets is used as an input element,and the economic contribution generated by the transportation industry is used as an output element.With the goal of creating the highest economic contribution of the entire transportation industry,the input of factors is optimized according to the constructed model.The results show that the transportation industry has a greater impact on the economy,the status of railways and highways cannot be shaken,and the air transportation industry has developed rapidly in recent years.With regard to the relevant research on the optimization of the allocation of factors in the transportation industry,the results of the study show that the investment in fixed assets in the railway and road transportation industries in my country’s transportation industry is unreasonable,and the fixed assets for railway and road transportation should be appropriately reduced or maintained Investment proportion,increase the proportion of fixed assets investment in waterway transportation and air transportation,especially air transportation.The empirical research in Beijing shows that Beijing should appropriately reduce the proportion of fixed asset investment in railway transportation.At the same time,the waterway transportation industry can maintain the necessary fixed asset investment in the industry.Beijing should allocate more fixed assets to road transportation and transportation.In air transportation,especially road transportation.Finally,based on the results of the empirical research,we draw conclusions and put forward relevant suggestions to improve the efficiency of factor allocation in the transportation industry.
