Empirical Study on the relationship between freight volume and economic development of provinces and cities in China

Abstract

The transportation industry is the basic and leading industry of the national economy, and it is an important pillar of the national economy. The freight transportation is an important part of the transportation and plays an important role in the economic development. At the same time, the development of freight transport itself is also affected by the economy. Therefore, this paper studies the relationship between cargo transportation and economic growth, and explores the internal relationship and law between them, so as to provide reference for the development of cargo transportation and the growth of national economy. This paper selects the freight volume and GDP indicators of 31 provinces and cities in China from 1993 to 2018, and discusses the development trend of GDP and freight volume from the perspective of provinces and cities. The results are as follows: 1. Freight volume and GDP showed an upward trend from 1993 to 2018, but the growth of freight volume was slower than that of GDP. 2. There is a co integration relationship between GDP and freight volume, and the national GDP increases by 0.954% for every 1% increase in freight turnover. 3. There are differences in the driving effect of freight volume in typical regions and provinces.
