近一、二十年以来，随着服务贸易在全球贸易额中的比重不断上升，发展中国家都十分重视包括海运和内河航运在内的运输服务贸易的对外开放。这不仅仅是权利和义务对等原则的要求，而且还体现了在多边贸易体制框架下，各国通过双边多边谈判，在“逐步自由化原则”下，所获实际利? In the past one or two decades, as the proportion of service trade in the global trade volume has been on the rise, all developing countries attach great importance to the opening up of the transport service trade, including shipping and inland shipping. This is not only a requirement of the principle of reciprocity of rights and obligations, but also reflects the actual profits gained under the “principle of progressive liberalization” through bilateral multilateral negotiations under the framework of the multilateral trade system.
