Well, the general outline is pretty much the same for all of the developed world. The so-called "major differences" between the systems of economics of the Anglo-Saxon world and the Continental European world are for most part imagined by left-wing extremists from the latter and the hard-right of the former.
China's economic model, with its complicated formation of businesses and lacking the possibility of private land-ownership (in the PRC, all land is state-owned and all land used by people and corporations is on lease) would be an example of an economic model that would be significantly different enough to warrant being considered distinct from the free-enterprise system that is now universally adopted among the developed countries.
Yeah, it's true that in practice all Western governments have followed basically the same neoliberal orthodoxy for a few decades now, and most disagreements are largely inconsequential. But the attitudinal differences are still there and are still significant. When the UK faced higher bond yields and a downgrade threat in late 2008/early 2009, even the Labour government at the time didn't knee-jerk into blaming speculators and saying that this would all blow over. All 3 main parties recognised that debt reduction was going to be the main focus of economic policy for the 5 years at least, and all 3 main parties aimed to reduce the deficit and national debt by the same amount (they only differed in how they were going to do that). British politicians generally accept that if you don't want to be at the mercy of bond markets, you shouldn't borrow from them in the first place. Compare that to what basically every Eurozone government has been saying for the past 2 years...
These attitudinal difference have a big impact on policy, especially in a downturn. It's one thing to grudgingly accept the idea that markets work better the freer they are when free markets are delivering consistent wealth growth and lowering your cost of borrowing. But now things are different, and those attitudes are going to cause big differences between the kinds of governments that understand economics and the kinds of governments that are naturally hostile to business, trade and free markets.
@Cutlass: I didn't mean "constrained" to carry with it negative connotations. I just meant that it has more constraints in its mandate, which it does: it has to manage economic activity, unemployment and inflation, whereas the only constraint on most other central banks is to manage inflation. Kaiserguard already said that its actions were more interventionist, i.e. less constrained.
