It argues that small venue theaters — the term it uses for the range of New York City theaters beyond Broadway — have an outsize cultural influence, often nurturing risky work, and reaching a wider audience with more affordable tickets.

And it suggests a link between the nonprofit theater world and the growing production of streaming content in the city, noting that some of the same artists work in both areas.

The study calculates that theaters aside from Broadway are responsible for $584 million in direct annual economic output, and estimates $1.3 billion in “direct, indirect and induced benefits.”

“Traditionally people have viewed this as a niche sector, but we found it’s a significant contributor to the creative sector in New York City, and also a significant economic driver,” said Anne del Castillo, the commissioner of the city agency.

And the study cites the success of recent shows such as “Hadestown” (first presented at New York Theater Workshop) and “The Band’s Visit” (at Atlantic Theater Company), each of which eventually reached Broadway and won the Tony Award for best new musical, as well as “Hamilton” (at the Public Theater) and “Fairview” (at Soho Rep), each of which won the Pulitzer Prize for drama. (“Hamilton” also won the Tony).
