Talking freight: inland waterway- Issues, Challenges, and opportunities.

今天听了一个webinar,是讲美国的内河运输系统的。两个presenters主要介绍了关于美国内河的硬件设施,包括船公司,船型,航道条件等。重点介绍了内河维护工程。
令人印象深刻的是,这些航道维护工程的资金来自政府以及内河的利用者(liner companies)
政府拨款很好理解,这是很常见的公共设施维护的资金来源。
那么those who utilize the waterway 的出资比例以及资金管理如何做呢?
美国采用的是首先fuel tax: 向使用这条内河的船公司征税,按油耗的正比例收,0.02/gallon 逐渐上涨到 0.2/gallon
然后这笔钱交给信托基金 Inland waterway trust fund 来管理,然后用于内河工程的修缮,比如修水闸 lock, Lower Monongahela 降低河床等projects.
改善河道条件,是有econimic benefits的,因此有公司甚至愿意提升自己的缴税比例(有种融资的感觉,虽然自己多缴纳5%的税,但是其他大公司也会相应交更高税,然后干更多钱的事情,享受更多利益)具体的决策过程应该挺有意思。缴税一方面是成本,另一方面又是会带来成正相关的收益。
