The International Federation of Arts Councils and Cultural Agencies IFACCA is offering online the 2015 survey on International Entrepreneurship in the Arts D’Art 48 which presents the results of a 2015 survey on International Entrepreneurship in the Arts, disseminated among its members.

The report has a list of examples of government support for international entrepreneurship in the arts which is quite limited but might be of use to some professionals. See page 10.
I can’t really tell how useful is this data as it comes from different professionals and seems based on estimations of those respondents rather than proven data but I invite you to check on your own.
