Abstract: The fixed pricing method of highspeed rail is a factor that restricts higher profits. In the face of the dynamic pricing mechanism of aviation， the scientific and reasonable pricing strategy of highspeed rail is the key to solving its lack of profit. Therefore， under the current mechanism， the article constructs a Hotelling model， analyzes the scope and revenue of highspeed rail static pricing and aviation dynamic pricing， highspeed rail dynamic pricing and aviation dynamic pricing， and compares the benefits of highspeed rail static pricing and dynamic pricing. The research results show that the implementation of dynamic pricing of highspeed rail can bring about an increase in revenue.

摘要： 高铁固定的定价方式是制约获得更高利润的因素，面对航空动态定价机制，高铁科学、合理的定价策略是破解盈利不足的关键。在现行机制下，构建Hotelling模型，分析高铁静态定价和航空动态定价、高铁和航空同时动态定价的均衡，比较实施高铁静态定价和动态定价的收益。研究结果表明，高铁实行动态定价能增加收益。
