I think if the labor cost is a small part of total cost, it might be more valuable to investigate the roughly 1:2 output per worker. Some possibilities, none confirmed:

- Chinese workers work 2 shifts instead of 3 shifts, so the factory simply hires less workers. This should also show a difference of total output of cars;

- Chinese factory has better processes or/and automation, which is more interesting.
