A popular development strategy at the state and regional level, incubators seek to support economic growth by providing entrepreneurs with business assistance, access to capital, and networking. As of 2012, approximately one-third of the 1,250 business incubators in the United States were connected with universities, up from one-fifth in 2006, according to International (formerly National) Business Incubation Association data featured in The New York Times. Despite the proliferation of these programs at universities, there have been relatively few conclusions to date on the impacts of these incubators beyond anecdotes. Recent research from faculty at the University of Central Florida (UCF), however, finds evidence that firms in university incubators experience positive growth in number of employees and sales at a statistically significant rate compared to non-university incubated firms. On average, the authors find that university incubated firms were responsible for 3.965 more jobs than non-university incubated firms.

A study titled Incubators, accelerators and urban economic development,[1] published in the Urban Studies Journal last year, found positive impacts on employment and access to capital for participants.
