Porter\'s National Diamond

Concentrate on rivalry first.

If a company was a monopoly in its own country it would have no incentive to improve to become world class. Hence Germany is good at cars and there are competing firms: VW, BMW and Nercedes. Japan is goos at cameras and has Olympus, Canon, Pentax and Nikon.

For strategy and structure think that some in some countries it is difficult to set up new businesses or they are kept in the hands of vested interests and this provides less opportunity for great firms to emerge.
