运用小波分析理论，对金融危机前后BDI指数与国内航运业上市公司代表中国远洋 H股股价波动的联动性加以实证研究。研究结果表明，两者的波动存在共变性与非一致性并存的显著特征，对来自金融危机的强烈冲击呈现较强的异质性波动规律。2008年金融危机前后，两者的相关性达到顶峰，大多时域及频域内，BDI指数波动领先于中国远洋H股股价波动。面对来自国际市场的负面冲击，完善风险抵御机制，提升危机应对水平，有助于国内航运业的健康发展和长期稳定。

This article makes an empirical study on the fluctuant correlation between the BDI index and the H share price of China Cosco ,a Chinese listed shipping enterprise ,with the application of the wavelet analysis .The result shows that there are co‐variance and non‐uniformity in various research cycles ,which is a heterogeneous fluctuation with strong impact of the financial crisis .The correlation between them reached its peak around the financial crisis in 2008 .In most time and frequency domains ,the BDI index fluctuates ahead of China Cosco's share price .Faced with the negative impact from the international mar‐ket ,it is helpful to the healthy development and the long‐term stability of the domestic shipping industry to perfect the risk resistance mechanism and improve the crisis response ability .
