The title is misleading. It may have less "steam" at the moment but it could coast for a while and still be out pacing it's rivals. Something I often wonder is how an economy can grow that fast and not be built of straw? Can you build an infrastructure that quickly and not have huge problems? According to your link, the real growth occurred from 2005 to 2010, in 5 years. This means in 2020 that infrastructure will start becoming dated and will need replacing. I see some real challenges for China in the future. Thanks for the GDP link.
You know, I just don't know the answer to this. I don't think it is necessarily a bad thing. A lot of infrastructure projects that people fund in taxes end up returning profits right back to the community in the form of wages and business opportunities around the new infrastructure which also generate revenue and feed wealth back into the system (private and public coffers).
