Industrial total output: China
Service output: the US
Efficiency: maybe Japan
Quality: Germany? Japan? not so sure
More things I want to put here are:
1) low efficiency of Chinese workers is a kind of "intentional". the most important thing for China is to keep millions of unskilled farmer workers have jobs, so that they can buy their living, but not try best to improve efficiency like put more capital
and less labor into the output equation. I believe that China can makes at least the same level of total output while leave tens of millions workers jobless, but, you know, how about these workers?
2) quality of Chinese product: actually China can produce almost everything you can imagine, but people just used to focus on craps you get from Dollar Tree or Walmart, while ignoring tags behind your iPad2 or other stuffs. As I said before, China needs
to produce low quality craps to keep tens of millions of workers employed, and it sells those crap successfully: people have choices to buy products with better quality but more expensive, but many just don't want to do so. Demand is always the main driver,
not the supply.
