The economy of Ohio nominally would be the 21st largest global economy behind Saudi Arabia and ahead of Argentina according to the 2017 International Monetary Fund GDP estimates.

The state was edged out only by Texas and Nebraska for the 2013 Governor's Cup award from the magazine, based on business growth and economic development. A new report by the Quantitative Economics and Statistics Practices (QUEST) of Ernst & Young in conjunction with the Council On State Taxation (COST), ranks Ohio as third in the nation for friendliest tax environment. The study, Competitiveness of state and local business taxes on new investment, provides a state-by-state comparison of tax liabilities. The top five states ranked with the lowest effective tax rate on new investment are: (1) Maine (3.0%); (2) Oregon (3.8%); (3) Ohio (4.4%); (4) Wisconsin (4.5%); and (5) Illinois (4.6%). Ohio is commonly noted as the Nation's Industrial Capital, dating to its roots in the Rust Belt and Ohio's present-day intelligence and scientific dominance. Ohio was one of four states in the U.S. to have areas make the Intelligent Community Forum's list of global Smart 21 Communities for 2014, with Columbus, Ohio receiving the honors. The state has 5 of the top 115 colleges in the nation, according to U.S. News and World Report's 2010 rankings, while the Ohio State University was ranked #10 by the same magazine for awarding degrees to Fortune 500 CEOs. The state was ranked #8 by the same magazine in 2008 for best high schools, while overall, in 2010 the state's schools were ranked #5 in the country by Education Week. However, by 2016 the state's high school rankings had slipped to #11 according to U.S. News and World Report, and #22 overall in quality by Education Week in 2017.
