Effects of economic incentives in the American film industry: an ecological approach
研究美国各州电影产业激励政策的效果，发现激励的存在、组织多样性和主导组织种群与拍摄量、就业和新企业增长相关。
US states have offered billions of dollars in film industry incentives, but despite the popularity of these incentives, the effects of these investments are unclear. This study adopts an ecological framework and tests the hypothesis that film incentives are effective when they produce changes in the composition of organizational communities. The results of longitudinal linear mixed-effects models, centred around incentive introduction in each state, show that above the impact of their dollar value, the simple presence of economic incentives, organizational diversity and the presence of dominant organizational populations are associated with increases in filming, employment and new establishments. Theoretical and policy implications are discussed.
