E-commerce would be defined as "commerce via the internet," in which commerce is the sale or purchase of goods or services. Short-run trade policies of e-commerce concentrating on B2C goods tend to be half-baked and need to be supplemented by policies towards services over the internet. Most of all, data localization issues will be at the heart of future trade policies regarding ecommerce. Korea is neither immune to, nor ready for data localization issues. It is time to construct a comprehensive panel dataset for e-commerce firms in manufacturing and services industries. Together with studies about the impact of e-commerce using such a dataset, Korea needs to make serious preparations to cope with digital localization issues with a balanced view.
