中文摘要:
      论文运用岭回归方法分析江苏省公路路网密度、高速公路通车里程、一级公路通车里程对社会物流费用占GDP的比率的影响。结果显示:对江苏省社会物流费用占GDP的比率的影响程度由大到小的公路交通因素分别是:公路路网密度、高速公路通车里程、一级公路通车里程。其中前两个因素的影响程度较为接近,第三个因素的影响稍逊一筹。
英文摘要:
      This paper analyzes the impact of the density of highway network in Jiangsu Province, the expressway mileage and the highway mileage on the GDP ratio occupied by the social logistic costs with the method of ridge regression. The results show that the highway traffic factors that influence the ratio of GDP range in degree from highway network density, expressway mileage and highway mileage. The influence of the first two factors is relatively approximate and the influence of the third factor is less significant.
