This paper mainly studies the relationship between the road freight industry in Guangdong Province and the development of national economy, and makes a correlation analysis. On the basis of summarizing and combing the present situation of road freight industry and national economy in Guangdong Province, we select the relevant economic indicators (road freight volume and road freight traffic volume) that can represent the development of road freight industry, analyze the data and calculate the relationship between it and The correlation coefficient between national economy index (GDP, the added value of the secondary industry and the added value of the tertiary industry) shows that the correlation between the value added of the road freight industry and that of the tertiary industry is higher, and the related indicators are analyzed by the linear regression It concludes that the infrastructure of road freight transportation industry in Guangdong Province is perfect and the transportation supply is sufficient.
