The total amount of digital travel sales worldwide increases significantly every year, yet previous studies on outbound tourism expenditures have scarcely discussed the role of foreign exchange control (Fxc) as a barrier to e-internationalization. In the era of e-commerce, residents of more than 40 economies are not allowed to buy or pay for foreign products by the Internet. This article, with data from 95 economies in the period 2012–2017, concludes that Internet penetration development increases international tourism expenditure. On the other hand, the control of foreign exchange decreases the relationship between internet penetration and tourism expenditure. Therefore, Fxc is clearly a barrier to electronic internationalization and tourism expenditure.

全球数字旅游销售总额每年都在显着增加，但之前关于出境旅游支出的研究几乎没有讨论外汇管制 (Fxc) 作为电子国际化障碍的作用。在电子商务时代，40多个经济体的居民不得通过互联网购买或支付外国产品。本文结合 2012-2017 年 95 个经济体的数据得出结论，互联网普及率的发展增加了国际旅游支出。另一方面，外汇管制降低了互联网普及率与旅游支出之间的关系。因此，Fxc 显然是电子国际化和旅游支出的障碍。
