With a GDP of over $23 trillion in 2021, the United States has the world's largest economy, according to the latest available data from the World Bank. Yet, the U.S. falls behind such countries as Israel and Korea when it comes to how much is spent on research and development (R&D) in proportion to GDP. For example, Israel and Korea spend 5.56% and 4.93% of their GDP on R&D compared to the U.S.’ 3.46%.
GDP is the sum of a region’s economic output, measuring economic productivity and innovation capacity. R&D is the process of generating new knowledge to create a novel product, service, or method. This article uses national expenditures on R&D calculated as a percentage of GDP to provide a standardized metric of R&D intensity. Later, a breakdown of the performing sectors of R&D is provided.
Exploring these metrics allows for establishing a benchmark of competitiveness. This article uses data from the World Bank and the Organization for Economic Co-operation and Development (OECD). Data includes GDP, gross domestic expenditure on R&D (GERD) as a percentage of GDP, and GERD by performing sector from 1960-2022 when available.
