著作权作为一种知识产权,具有客体无形性和权利多样性的特征。我国法律虽然规定了著作权的转让制度,但是并不详尽完整,导致现实生活中著作权的“二重转让”问题频频发生。因此有必要建立著作权转让的公示制度,从而避免著作权领域中“二重转让”问题的发生,以营造良好的市场交易环境。 As a type of intellectual property, copyright has the characteristics of intangible object and diversity of rights. Although China’s law provides for the transfer of copyrights, it is not exhaustive and complete, resulting in frequent occurrence of “double transfer” of copyright in real life. Therefore, it is necessary to establish a publicity system for the transfer of copyright so as to avoid the occurrence of the “double transfer” problem in the field of copyright so as to create a good market trading environment.
