我国《著作权法》第4条:“依法禁止出版、传播的作品,不受本法保护。著作权人行使著作权,不得违反宪法和法律,不得损害公共利益。”在中美知识产权争端案中被指违反了国际公约及所承担的国际义务。WTO专家组的意见促使我国修改了《著作权法》第4条。但是我们应该清楚地认识到对影视作品版权的保护不是仅仅修改《著作权法》第4条即可解决的,最根本的还是需要我们对现存的制度予以改革和完善。为此,笔者以我国的电影审查制度为研究对象,提出确立电影分级制度来完善我国对影视作品版权的保护。 Article 4 of the Copyright Law of China: “Works that are prohibited from being published or distributed according to law are not protected by this Law.” Copyright owners exercise their copyright and may not violate the Constitution and the law, nor damage the public interest. "In the Sino-US intellectual property dispute case Allegedly violated the international conventions and their international obligations. WTO Expert Group’s opinion prompted our country to amend Article 4 of the Copyright Law. However, we should clearly recognize that the protection of the copyright of film and television works is not only solved by the amendment of Article 4 of the Copyright Law. The most fundamental issue is that we need to reform and perfect the existing system. Therefore, the author takes the censorship system of our country as the research object and proposes to establish the film classification system to improve our country’s copyright protection of the film and television works.
