For domestic films, the box office is divided as follows:
5% of the special fund for film development, 3.3% of the consumption tax paid to the national film management department, and
paid to the national tax department. The above part is determined by national laws and regulations, and no one can move it (if the box office of domestic films shown in cinemas accounts for more than 5% of the total box office, It can be exempted from the special fund for film development)
The remaining 42-45% will be given to producers and distributors
55-58% will be given to cinemas and projectionists
The specific proportion will be decided through negotiation between distributors and cinemas. There is no regulation, and the national film management department has only one guidance.
Because China's film market is still an obvious buyer's market, only a few films are made every year in China, so cinemas obviously have more right to speak, have advantages in negotiation, and of course take a high proportion, which is determined by market rules.
