摘要
本文主要研究了广东省道路货运业与国民经济发展的联系,进行相关性分析。在总结、梳理广东省道路货运业与国民经济发展现状的基础上,选取能够代表道路货运业发展的相关经济指标(道路货运量、道路货运周转量),对数据进行整理分析,并计算其与国民经济相关指标(GDP、第二产业增加值、第三产业增加值)的相关系数,结果显示道路货运业与第三产业增加值的相关程度更高,并对相关的指标进行一元线性回归分析,得出广东省道路货运业基础设施完善,运输供给充足,同时广东省道路货运服务水平与宏观的发展具有较高的相关性,对经济发展具有促进作用。
This paper mainly studied the correlation on road freight industry and national economic development in Guangdong. We selected and analyized the relevant economic indicators which can represent the development of road freight transport industry （road freight volume, road freight turnover） and related national economy indicators（GDP, the value-added of the secondary industry, the value-added of the tertiary industry）. The results showed that the correlation between the road freight industry and the value-added of the tertiary industry is higher, and analyze the related indicators with one-dimensional linear regression equation. The conclusion is that the infrastructure of the road freight industry in Guangdong is perfect, and the supply of transportation is adequate. The service level of road freight in Guangdong has a high correlation with the macro-economy development which has a positive effect on the promotion of economic output.
