How does Alipay's user experience compare to Paypal's? Is it the lack of competition that has enabled them to expand their reach so widely (by not having to focus so much effort on each venture)? For example, the experience of shopping on AliExpress is (imo) sub-par when compared to most Western online shopping experiences I've had (Amazon, Zappos, and even smaller retailers).
I don't know a whole ton about the Eastern market to be honest, so I'm open to being educated.
I think it partially explains Alibaba's success in China. how you do shopping and paying is very much dependent on the "tradition" and regulation environment, and a local company can optimize that better than a global one.
Aliexpress is a mess though, i agree with that. But I think the language barrier faced by the shop owners there may be the biggest problem.
To your question "Is it the lack of competition..." I would say this is not the case. There has been plenty of competition. Alipay grew its adoption on its integration with Taobao in similar ways as PayPal was integrated with eBay.
They also contributed a pile of money to EdX. Those are 2 examples off the top of my head
cloud services ---- google cloud platform
mobile apps ---- google play
mobile OS ---- android
maps and nav ---- google maps
physical retail ---- ? no google product
shopping deals ---- google offers
cloud storage ---- google drive
instant messaging ---- google hangouts
car service ---- uber (via google ventures)
c2c ecommerce ---- ? no google product
travel booking ---- google flights
b2c ecommerce ---- ? no google product
e-learning ---- ? no google product
social media ---- google+
music streaming ---- google play music (all access)
video streaming ---- youtube / google play movies
money market ---- ? no google product
all the western companies you'd have to combine to cover alibaba's markets would seem to me to be google, and maybe one or two others. i included uber because i know about that one, you could probably fill in a few more gaps with other google ventures companies.
