摘　　要：当前对运输成本的分析较为笼统,缺乏具体针对公路货运企业成本的分析。公路货运与其它运输方式货运相比成本有很大的区别。通过比较研究公路货运企业的短期成本和长期成本的性质,得出了公路货运企业成本的弱垄断性。并采用超越对数成本函数对成本进行分析,根据超越对数成本函数的性质验证了公路货运企业的规模效应。The analysis of freight cost is relatively in general tenns, lack of specific analysis according to road freight enterprise.Road freight cost is different from other trensport mode freight＇ cost.
