A survey by The Nielsen Company has found mainland visitors spend an average of HK$12,000 ($1,540) each when they come to Hong Kong.
Nearly 60 percent of that is spent on shopping, mainly on cosmetics and electronic goods. Twenty-three percent is spent on accommodation, and 18 percent on food.
Some 500 mainlanders were interviewed towards the end of last year by the global consumer research firm.
What's interesting is that these shoppers did their homework before coming to Hong Kong, relying on word of mouth as well as online forums and blogs for information. They also found information from TV shows, newspapers and online advertising.
Some of the other popular items they bought were jewelery, clothes, medicine, food (powdered milk?), souvenirs and handicrafts.
This shows that most of those interviewed were young people who are internet savvy and bringing shopping lists to help buy stuff for other people.
While companies targeting mainland shoppers should consider a greater web presence or more online advertising, mainlanders really are looking at well-known brands because we all know they can't trust what's for sale at home.
