다국어 초록 (Multilingual Abstract)

Generally, the tonnes lifted and tonne-kilometers are widely used to analyze the road freight transport. However, these two indicators are simply to show the road freight transport statistics rather than to esplain the road freight transport system. In this study, the variables such as the number of distribution channel levels, the integral distance, tonnes in transportand the average transport distance are defined and estimated to investigate the road freight transport system of Korea. In order to compare the road transport system of Korea to other countries. the comparative study was conducted including USA, Japan, Netherlands, Taiwn. The major findings of this study are as follows: ⅰ) The number of distribution channel levels and integral distance of Korea and Taiwan have been increased, but the average transport distance decreased from 1971 to 1996 period. ⅱ)On the contrary to Korea case, the number of distribution channel levels and integral distance of US, Japan and Netherlands have been decreased, but the average transport distance increased. ⅲ) In the time-series model analysis shows that the number of distribution channel levels are statistically positively related to the cost of logitics as well as the cost of transportation as a percentage of GDP.
