Answer: c. Strategy and rivalry
Step-by-step explanation:
Porter's Diamond Theory of National Advantage is a model that attempts to show how businesses can obtain a competitive advantage in their industry.
Strategy and Rivalry fall under this model and attempt to explain that a company that has STRONGER domestic competition can emerge very strongly and compete better on the World stage.
Why?
Because it is theorised that if there was plenty of competition in the local market, a firm would then develop various strategies and structures that would help them survive the intense competition and they can then use these same Strategies and Structures to compete and thrive on a global stage.
Kodak did not have that much of a competition in the United States and so did not have the stated structures and strategies that had been fashioned from intense competition and so found it hard to penetrate the rest of the world.
For Instance, European countries dominate in World Football ( Soccer) because they have very strong domestic leagues where their players are tried and tested so that when they come into the world stage they dominate against countries where competition is not very strong.
