Top 10 Countries With Most Expenditure on R&D

Research and Development (R&D) is an important factor in terms of innovation, economic growth, and technological advancement. Global R&D spending reached an impressive $2.8 trillion, reflecting a dramatic increase from $1 trillion at the turn of the century (adjusted for inflation). This hike underscores the critical role that R&D plays across industries such as healthcare, defense, technology, and green energy.

According to the latest data from the OECD, the countries leading the world in Research and Development investment show a firm commitment to innovation, mostly driven by both government and private sector funding.
