进入新世纪,在经贸发展的带动下,我国港口吞吐量快速发展,虽然港口建设也取得了很大成就,但吞吐能力增长落后于需求增长,使港口投资价值日益显现。本文结合港口类股价和大盘指数关系,分析了独立于大盘走势的原因和影响港口类股价变化的影响因素,从投资效益角度,论述了港口长远良好的投资价值。 In the new century, under the guidance of economic and trade development, the throughput of China’s ports has been developing rapidly. Although great achievements have been made in the construction of ports, the growth of throughput capacity lags behind the growth of demand, making the investment value of ports increasingly apparent. Based on the relationship between port stock price and market index, this paper analyzes the reasons of independent stock market trend and the influencing factors of the change of port stock price. From the point of view of investment benefit, it discusses the good long-term investment value of port.
