A Study Of Regional Differences In The Impact Of Four Major Modes Of Transport On Economic Growth And Their Spatial Spillover Effects

The transport sector is a basic industry of the national economy and is essential for the transportation of raw materials,the circulation of goods and the movement of labour.Studying the changes in the economic effects of different modes of transport on various sectors and focusing on the differences in their performance in different regions can provide reference for the development planning of different modes of transport and the formulation of transport policies.Firstly,the regional differences in the impact of the four main modes of transport on economic growth and the current status of the spatial spillover effects of the transport sector are discussed in this thesis,the ways in which the transport sector affects economic growth,the factors and mechanisms influencing regional economic differences and the impact on spatial spillover benefits are analysed.The strengths and weaknesses of the four main modes of transport and their current state of development are described.A theoretical basis is provided for the study of the differences in the regional economic effects of the four modes of transport on economic growth.Secondly,based on the input-output tables of 2007,2012 and 2017,the positions of the four modes of transport in the national economy are compared and analysed in this thesis,and the four modes of transport are used as four economic sectors,and backward and forward linkage models,demand-pull models,supply-push models,and price change models are constructed to study the economic impact of the four modes of transport-rail,road,waterway and air-on 39 sectors The impact of the four modes of transport on the economy is studied.The study finds that the demand-pull effect of the transport sector mainly affects the secondary industry sectors such as oil and gas extraction,petroleum coke and transport equipment manufacturing;the backward and forward linkage of the air transport industry is the strongest of the four modes of transport,the undersupply of the railway transport sector is the most obvious among the transport sectors.Subsequently,the differences in the impact of the economic effects of the four modes of transport in different regions are studied.Based on the demand-pull and supply-push models,the push-pull coefficients of the four modes of transport on economic growth are calculated for each province in 2007,2012 and 2017 in this thesis,and the study finds that the push-pull effect of the four major modes of transport on economic growth generally shows a "high in the west and low in the east" in spatial terms in 2012,with all four major modes of transport having a higher economic impact on the western region,followed by the eastern region.Finally,by constructing a spatial econometric model to study the impact of the operation level and infrastructure construction of the four major modes of transport on economic growth,after LM test and Hausman test et al,it is determined that railway transport should choose the time fixes effect model of SLM,road transport should choose the individual fixes effect model of SDM,water transport should choose the time fixes effect model of SLM,and air transport should choose the time fixes effects model of SLM for regression.The results of the study finds that,overall,the level of operation of all four major modes of transport is not as strong as the spillover effect of transport infrastructure construction on economic growth,and that emphasis should be placed on the development of multimodal transport and the construction of integrated transport hubs to improve the management and organisation of the transport industry.The construction of aviation infrastructure has a strong positive spatial spillover effect on the western economy,so the construction of aviation infrastructure in the western region should be strengthened to help promote economic growth in the western region.
