If we're going to appeal to authority Micheal Porter, the most cited author in business and economics and six-time winner of the McKinsey Award for the best Harvard Business Review article of the year agrees : Porter wrote "The Competitive Advantage of Nations" in 1990. The book is based on studies of ten nations and argues that a key to national wealth and advantage was the productivity of firms and workers collectively, and that the national and regional environment supports that productivity. He proposed the "diamond" framework, a mutually-reinforcing system of four factors that determine national advantage: factor conditions; demand conditions; related or supporting industries; and firm strategy, structure and rivalry. Information, incentives, and infrastructure were also key to that productivity.
