Anyone read Michael Porter?

Michael Porter wrote some seminal books on competition during the eighties focusing on strategy over operational efficiency as the focus of business differentiation.

I'm not familiar myself with his stuff, but it intrigues me how the vocabulary in his books are pretty much the spoken vernacular in business language.

So, that aside, I was wondering what you guys might know about Michael Porter's thoughts on international competition.

He makes the point that there are three basic stages in a country's development. A country is first:

A Factor Driven Economy: Comparative Advantage in natural resources, labor cost, and inputs.

Investment Driven Economy: ?

Innovation Driven Economy: Discovering new technologies and creating new ways of doing things.

As you can see I know every little. Can anyone tell me what an Investment Driven Economy is and how it is different from a Factor Driven Economy?

Thanks UG Brains.
