此项研究主要考察电影配额制及其它相关因素对电影市场自给率的影响。回归模型表明,配额制与自给率正相关的假设并不成立,因而暗示了配额制或许并不能有效地限制国外电影进入本国市场。国内生产总值、票房收益和制作投资被认为是决定自给率的最强有力的三大因素,而文化折扣和英语语言是非决定性因素。 This study examines the effect of the film quota system and other relevant factors on the self-sufficiency rate of the movie market. The regression model shows that the assumption that the quota system is positively correlated with the self-sufficiency rate does not hold, suggesting that the quota system may not effectively limit the entry of foreign films into the domestic market. Gross domestic product, box office receipts and investment in production are considered the three most powerful determinants of self-sufficiency, while cultural discounts and English language are non-determinant.
