Research On The Influence And Prediction Of Industrial Structure Adjustment On Transportation Demand

Transportation industry is the basic leading industry of national development,which plays an important role in the sustainable development of social economy.However,the optimization and adjustment of industrial structure will cause the transformation of industrial sectors in terms of quantity and structure,and then affect the regional transportation demand.It is of great practical significance to accelerate the adjustment of industrial structure,build a modern industrial structure system and comprehensively measure the impact of industrial structure adjustment on transportation demand.First of all,this paper summarizes the relevant theories of industrial structure and the connotation of transportation demand,summarizes and analyzes the mechanism and influencing factors of transportation demand,analyzes the key degree of influencing factors according to Boolean algebra operation rules,and selects the reasonable influencing factors for building a complete decomposition model.Secondly,according to the selected influencing factors of transportation demand,a complete decomposition model based on three factors of input-output table,i.e.economic level,proportion of industrial structure and complete consumption coefficient in the input-output table,is established.Based on the input-output table data of Sichuan Province in 2007 and 2012,the effectiveness of the complete decomposition model is tested.Furthermore,the paper analyzes the relationship between the three industries and the demand of transportation in Sichuan Province from 2007 to 2012,and judges the industrial sectors that have a greater impact on the demand of transportation.Finally,based on the input-output table of Sichuan Province in 2007 and 2012,the paper forecasts the complete consumption coefficient of the input-output table in 2022 according to the RAS method and MATLAB programming,analyzes the impact of the industrial structure adjustment of Sichuan Province on the transportation demand in2012-2022,judges the leading industries affecting the transportation demand,and influences the three industries in Sichuan Province on the transportation demand in 2007-2012 The response relationship is compared and analyzed,and some suggestions are given.
