Study On Regional Differences And Influencing Factors Of Highway Development Level In China

In recent years,with the continuous growth of my country’s transportation infrastructure investment,the level of highway development has increased substantially.Highways are an important part of transportation infrastructure,occupying more than 75%of the market in transportation services,and are of great significance for promoting regional economic and social development.However,due to different resource endowments,economic levels,and political environments in different regions,there are qualitative and quantitative differences in the scale and transportation capacity of highway construction.The regional differences in highway development will further restrict the potential of regional economic and social development and affect the fairness and efficiency of regional development.Therefore,this paper reveals the regional development gap by constructing a model of highway development level differences,uses panel data models to conduct an empirical analysis of factors affecting highway development,and selects typical cases for in-depth analysis on this basis,and proposes countermeasures to promote the balanced development of unbalanced regional highways.From the perspective of fairness and efficiency,the research proposes to measure the spatial distribution of highways and the distribution of highway transportation with comprehensive highway density and comprehensive transportation density,and introduce the Gini coefficient model of economics to measure the gap between the spatial distribution of highways and transportation distribution in my country.In order to study the influencing factors of highway spatial distribution and transportation distribution,we further selected population density,urbanization rate,GDP per capita,industrial structure,financial expenditure per capita,and social fixed assets per capita as explanatory variables.As the explanatory variables,a variable coefficient panel data model was constructed to quantitatively analyze the six explanatory variables.Finally,Shandong and Jiangsu are selected as excellent road development cases,and their road development models and development experiences are excavated to make policy recommendations.The study found that there is an imbalance in the spatial distribution and transportation distribution of highways in 31 provinces and cities in China,and the imbalance between the two has been continuously decreasing;the imbalance in spatial distribution and transportation distribution mainly comes from the four regions of east,central,west,and northeast.Regional differences,the proportion of inter-regional gap contribution rate is as high as 70%,while the intra-regional gap contribution rate is only about 20%.In terms of the subregional gap and intraregional gap,the contribution of each region is the first in terms of spatial distribution and transportation distribution in the western region.Population density,urbanization rate,GDP per capita,fiscal expenditure per capita,and social fixed assets per capita have a significant impact on the spatial distribution and transportation distribution of highways,while the industrial structure only has a positive effect on the spatial distribution of highways.The study concluded that highway development strategies can be formulated from four levels: speeding up the urbanization process,improving fiscal transfer payments,innovating investment models,and strengthening regional cooperation.This article studies the regional differences and influencing factors of highway development level from a regional perspective,reveals the current status of regional gaps in highway development level,identifies the influencing factors of highway development level,and grasps the future development trend of regional highways.It provides decisionmaking reference for the central government’s transportation transfer payment and the local government’s scientific arrangement of road network construction investment.
