The report "Understanding the U.S. National Innovation System" identifies the broad elements that make up a national innovation system, including a description of the innovation success triangle, which measures the business environment, regulatory environment, and innovation environment of a nation, and is used to predict the success of an innovation system in promoting technological development and economic growth. It then uses this framework to analyze the U.S. national innovation system and assess the strengths and weaknesses of individual components and whether those components are improving, stable or deteriorating relative to US-competitors.
