(1) The principle of protecting authors' rights and interests. Protecting the author's rights and interests refers to both the property right and the personal right of the work. The author's hard work is the source of literature, art and scientific progress in the whole society. Strengthening the protection of the author's rights and interests and recognizing the author's personal rights and property rights in his works is precisely to protect the author's creative enthusiasm and increase the spiritual wealth of the whole society.
(2) The principle of encouraging the dissemination of excellent works. Communication connects the creation and use of works. Although communication does not directly create works, it still needs a lot of manpower and material resources. Today, the development of reproduction technology makes infringement extremely convenient, and its legal protection is becoming more and more important. The fourth chapter of China's Copyright Law clearly stipulates that the rights of the main disseminators of works are the direct embodiment of the principle of encouraging the dissemination of excellent works.
(3) The principle of coordinating the author's interests with the public interests. Today's works are developed on the basis of outstanding achievements of predecessors. Although they can be regarded as the author's personality symbol and property right, they are a part of the spiritual wealth of the whole society, and no one, including the author, should monopolize them absolutely, so as not to hinder the overall progress of the whole society, culture, art and science. .
(4) The principle of keeping consistent with the development trend of international copyright. Encouraging the creation and dissemination of excellent works and promoting the development of social economy and culture is the basic purpose of implementing copyright legislation in all civilized countries. Although copyright is strictly regional, with the development of communication technology and the expansion of international copyright trade, many excellent works have gone abroad and become the spiritual wealth of all mankind. Therefore, it is particularly important to strengthen international copyright coordination and try our best to make the level of copyright protection basically the same in all countries on the premise of respecting the national conditions of all countries.
