文章对国内外相关的文献进行了定量统计，解析了当前的研究热点，分析了大数据时代科学数据共享面临的新问题并预测了未来可能的研究方向。研究发现：科学数据共享伦理的研究热点主要集中在伦理理论、伦理困境、问题成因、治理措施等方面。在大数据时代，科学数据共享面临着数据边界扩张、数据结构多样、数据权益模糊等新的伦理问题，未来研究可以关注数据鸿沟、数据污染、数据隐私、数据异化等问题。

The paper had carried out quantitative statistics on relevant literature at home and abroad, resolved the current research hotspots, analyzed the new problems faced by scientific data sharing in the era of big data, and predicted some possible research directions. The authors found that, the research hotspots of scientific data sharing are mainly focused on ethical theory, ethical dilemmas, and causes governance measures and so on. In the era of big data, scientific data sharing faces new issues, such as data boundary expansion, various data structures, and blurred data rights. Future research can focus on issues such as the data divide, data pollution, data privacy protection, and data dissimilation.
