In a nutshell, Blue Ocean Strategy proposes that strategy can shape industry structure, whereas competitive strategy sees strategy as choosing the right position under given structural constraints. The field of strategy has been long dominated by a structuralist view; in other words, the idea that the industry's structure is fixed. Strategy, as commonly practiced, tees off with industry analysis and is conventionally about matching a company's strengths and weaknesses to the opportunities and threats present in the existing industry. Here, strategy becomes a zero-sum game where one company's gain is another company's loss, as firms are bound by existing market space.
