The relationship between intellectual property protection and technological innovation and economic development is not a single linear relationship.This is both the conclusion of the study of the Stiglitz Report and the opinion of international organizations such as WIPO. A developmentally oriented intellectual property system rather than a rent-seeking-oriented intellectual property system needs to be carefully designed to promote innovation and conform to China's development stage and industrial characteristics.When setting up an intellectual property system, it is necessary to promote the technological innovation, and keep a balance between intellectual property creators and social interests. In addition, it is necessary to protect intellectual property rights as well as the development needs of an open intellectual property system. At the same time, it is necessary to pay attention to the important role of enterprises and individuals in scientific research and technological innovation, as well as the important role of the government. Useful attempts around an open intellectual property system are worth encouraging.
