✔ 最佳答案
The reason is it is not business viable.
1. Online market in Hong Kong is not big enough for Amazon. Either the demand is too small (like online bookstore); or the competition is too high (like Alibaba).
2. It takes a huge cost for Amazon to setup a base in Hong Kong (Due to customs issue, Amazon usually ships locally. The rent in Hong Kong is going to diminish any profits).
3. Local major businesses will team up and boycott Amazon due to competition.
