Study on border effects for shipping trade based on gravity model

摘要

This paper puts forward a border effect model derived from the widespread Gravity Model for shipping industry to study the significance of trade barriers caused by the regional border in ports. The result shows that economic size, cargo handling capacity and berth number of a port greatly influence the bilateral shipping trade while pier length does not show an obvious effect on shipping trade. Border effects between China and US for shipping trade do exist but is not quite significant based on the data of 2004–2009.
