本文以成渝直线高速公路为例,借助成渝高速公路的相关数据,分析了成渝高速公路通车以来的交通量和沿线资阳市、璧山县、双桥区三地国内生产总值(GDP)之间的相关关系,得出了高速公路与各地GDP之间存在高度正相关关系,然后,运用灰色系统GM(1,1)模型预测在2006-2009年间有成渝直线高速公路存在的情况下,安岳县的国内生产总值(GDP)的变化,进一步说明了成渝直线高速对沿线经济发展起到了加速的作用。
Taking the Chengdu-Chongqing expressway as an example, this paper analyzes the traffic volume of the Chengdu-Chongqing Expressway since it opened to traffic and the gross domestic product (GDP) of the three places along Ziyang, Bishan and Shuangqiao districts along the Chengdu-Chongqing Expressway. ), The paper concludes that there is a high degree of positive correlation between expressways and local GDP. Then, using the gray system GM (1,1) model to predict the existence of the expressway between Chengdu and Chongqing in 2006-2009 , Anyue County’s gross domestic product (GDP) changes, further illustrates the Chengdu-Chongqing straight high-speed economic development along the line has played an accelerating role.
