| During the "13th Five-Year Plan" period,in the face of a complex external environment,especially under the impact of the new crown pneumonia epidemic,the economic growth of Liaoning Province was slow,and the transportation industry,as a leading industry in economic development,played a role in connecting various subsystems of social economy,and its good development can promote regional economic growth.At present,the transportation industry in Liaoning Province has formed a modern comprehensive transportation with a variety of transportation that complements each other and develops together.Therefore,the study of the impact of comprehensive transportation in Liaoning Province on regional economic growth provides a theoretical basis for liaoning transportation industry to better support the rapid economic development.Based on the relationship between the comprehensive transportation industry in Liaoning Province on regional economic growth,this paper conducts an empirical analysis based on the transportation and economic data of Liaoning Province from 1990 to 2019,and explores the impact of different modes of transportation on regional economic growth.Establish a regression equation in the three aspects of infrastructure construction,passenger capacity,and freight capacity.The unit root test and cointegration relationship test are performed on the data to determine the optimal test form.Then perform the Granger causality test.The results show that the three modes of transportation have a significant impact on economic growth in three aspects,among which,in terms of infrastructure construction,the contribution of road transportation to economic growth is positively correlated,while railway transportation is negatively correlated.In terms of passenger capacity,road transportation,railway transportation,and water transportation are positively correlated with economic growth,and the GDP of Liaoning Province will increase by 0.064 units by increasing the volume of road passenger traffic by one unit;the GDP of Liaoning Province will increase by 0.039 units by increasing the volume of railway passenger transportation by one unit.Although water transport has a promoting effect,its contribution is relatively small.In terms of cargo transportation capacity,road,water transportation,and railway are positively correlated with economic development,and to the extent of promoting economic development,water transportation > railway transportation> road transportation.Secondly,in order to explore the impact of the comprehensive transportation development of Shenyang and Dalian on the economy of Liaoning Province,this paper selects the economic data of Shenyang,Dalian and Liaoning Provinces from 2015 to 2019,and conducts an empirical study through the gray correlation analysis method,and the results show that the correlation between most of the transportation indicators in Shenyang and Dalian and the economic indicators of Liaoning cities is higher than 0.65,which is a strong correlation;the transportation indicators of Shenyang and Fuxin,Panjin GDP,The correlation between Chaoyang GDP and other economic indicators is high;the correlation between Dalian’s transportation indicators and Huludao GDP,Shenyang GDP,Fushun GDP,Jinzhou GDP and other economic indicators is high;in the comparative analysis of Shenyang and Dalian,the correlation between Shenyang’s transportation indicators and the economic indicators of various cities in Liaoning Province is higher than that of Dalian.Finally,based on the empirical results and the development status of Liaoning Province,it is proposed to actively build comprehensive transportation and achieve coordinated development of various modes of transportation;rationally plan regional layout and give full play to the advantages of central cities;improve operational service capabilities and build a low-carbon green scientific operation model. |
