摘要
随着各大港口铁矿石业务竞争日益激烈,Z港货源市场占有率被压缩.通过将常规的两个港口间的一维Hotelling博弈拓展至五个港口间的二维博弈,在完全信息条件下,针对Z港所采取的竞合策略构建静态博弈模型,并借助于Nash均衡,求解最优港口收费标准,探讨影响港口收益的相关因素.实证分析表明,相较于单独竞争,Z港与B港开展合作,向粤东及长三角区域进行业务扩张,可以在一定程度上提高竞争力,增加其整体收益.
With the increasingly competitive of iron ore business among major ports,the supply market share of port Z has been compressed.By extending the one-dimensional Hotelling game between two ports to the two-dimensional game between five ports,a static game model was constructed under the condition of complete information,and by means of Nash equilibrium,the optimal port charges were sloved and the related factors of affecting the port revenue were explored.The empirical analysis shows that compared with the separate competition,the cooperation between port Z and port B,and the expansion of business to the northeast,to a certain extent,can improve competitiveness and increase their overall revenue.
