The correlation between GDP and different transport modes turnover based on grey correlation analysis

Abstract

Transportation is the inherent law of economic development. With the deepening of reform and opening up, the adjustment of economic and industrial structure, transport volume have driven GDP growth to varying degrees. Therefore, based on the 1990-2017 transport turnover and GDP in China, this paper studies the decoupling relationship between GDP and transport volume at different stages, in which traffic volume has a week decoupling with GDP. By using the grey correlation analysis, the degree of correlation between different freight and passenger transportation modes at sample period is calculated to demonstrate the similarity with economic growth.
