摘要

目前，全球变暖导致海洋自然灾害显著增加。学术界有必要对海洋自然灾害对中国航运业的影响进行定量评估。事件研究表明，海洋自然灾害导致中国航运业的负异常交易量和异常股票收益。此外，回归分析结果显示，异常交易量与异常股票收益呈正相关。总体而言，海洋自然灾害可能会降低投资者对航运公司发展的预期，从而对航运公司的市场价值产生不利影响。本文的研究结果强调了灾害管理在航运业中的重要性，建议航运业管理者应加强灾害管理。我们的研究为自然灾害的经济影响和不确定性对企业投资的影响的研究领域做出了贡献。

The impacts of natural marine disasters on shipping industry in China: An event study

Currently, global warming leads to a notable increase in natural marine disasters. It is imperative that the academic community undertake a quantitative assessment of the impacts of natural marine disasters on shipping industry in China. The event study revealed that natural marine disasters lead to negative abnormal trading volume and abnormal stock returns for the Chinese shipping industry. Moreover, the findings of the regression analysis indicated that abnormal trading volume was positively related to abnormal stock return. Overall, natural marine disasters may lower investors' expectation on the development of the shipping firms, which would adversely affect shipping firms' market value. The findings of our paper highlighted the importance of disaster management in the shipping industry, which suggests managers in shipping industry should improve disaster management. Our research contributes to the research area of the economic effects of natural disasters and the effects of uncertainty on firms' investments.

期刊介绍： The Journal of Sea Research is an international and multidisciplinary periodical on marine research, with an emphasis on the functioning of marine ecosystems in coastal and shelf seas, including intertidal, estuarine and brackish environments. As several subdisciplines add to this aim, manuscripts are welcome from the fields of marine biology, marine chemistry, marine sedimentology and physical oceanography, provided they add to the understanding of ecosystem processes.
