"快闪商店"，一种在短时间内开张的商店,近来在欧美非常流行.

NPR News: Fast-rising mobile technology is making buying stuff with a tap of an app easier than ever, and shifting the way we shop. What were once permanent stores, where shoppers look at items in a physical space, are now often pop-ups first.

Pop-up shops are temporary retail spaces that spring up in unused premises. Leases can last as short as a single day, when brands use the spaces for a promotional event instead of testing out a market.

These days, the pop-up concept is proliferating in trendy, high-foot-traffic neighborhoods like SoHo.

Los Angeles-based retail industry consultant Syama Meagher has been watching pop-up retailing develop for the past half decade.

"With food trucks becoming more and more open and available, and the kind of migration of bringing that, I actually think that pop-up shops kind of followed suit."

As consumers do more and more on mobile devices, short-term leases promised by pop-ups mean brands can be more mobile, too — moving around to where their customers cluster.

"Larger online brands are bridging together these empty spaces and starting to find ways to get in front of their customers."
