"Prosperity in a nation comes from only one thing, and that's productivity" is how Porter explained a nation's competitive advantage. A country with high productivity will have a strong currency and high wages, and this will result in wealth and improving living standards.
「所謂競爭力，就是生產力」，這是波特對「國家競爭力」開宗明義的解釋，而一個國家的生產力高，意味著貨幣強勢、薪資提高；反映在外的，是社會的繁榮富裕與生活水準改善。
