The Business Insider put together this useful chart based on statistics from CNNIC. It's particularly interesting to see that while the US Internet users engage in a lot of commerce/business related activities, Chinese users engage in relatively more online entertainment. Perhaps this is a reflection on the maturity of the market or indeed average age of users, and maybe we'll see a shift over the next couple of years towards percentages that more closely resemble US users' Internet usage.
Another possible interpretation is that Chinese Internet users don't yet feel safe or comfortable engaging in financial transactions online, and again this should improve as China catches up with solutions for safer online commerce.
