As a result, getting the answer of the cruise industry of corresponding relationship with the access capability of potential competitors, the bargaining capability of suppliers and buyers, the replacing capability of substitutes, industry competitors existing competition ability. From these relations, it summarizes the cruise industry core competitive advantages, such as high quality service, high differentiation of user experience and so on. At last, through the corresponding analyze of the strategy, providing useful advice for the sustainable development of cruise industry.展开更多
