具有较高教育水平的海外留学生通过到国外考察、交流学习，可以加强贸易双方的沟通，增进相互了解，降低贸易成本、降低对外贸易的风险和不确定性，并提高出口贸易的人才储备。选取2002~2015年中国对55个国家的出口数据，使用贸易引力模型探究了中国海外留学对中国出口贸易的影响。实证检验发现：中国海外留学总人数对中国总出口并没有显著影响，但不同经济发展程度国家以及不同规模留学人数中，海外留学对中国出口的影响不同。结合研究结论，为促进中国贸易持续发展，文章最后提出鼓励海外留学和国外学生来华留学。Overseas students with higher education level can strengthen the communication between trade parties, enhance mutual understanding, reduce trade costs, reduce risks and uncertainties of for-eign trade, and improve the talent reserve of export trade by visiting and studying abroad. Based on the export data of China to 55 countries from 2002 to 2015, this paper uses the trade gravity model to explore the impact of Chinese overseas study on China’s export trade. Empirical tests show that the total number of overseas students in China has no significant impact on China’s total exports, but the impact of overseas students on China’s exports is different in countries with dif-ferent economic development levels and different scales of overseas students. In order to promote the sustainable development of China’s trade, the article finally proposes to encourage overseas students and foreign students to study in China.
