The formulation of Intellectual property chapter in China’s free trade agreements is an important part of China’s participation in international intellectual property governance. However, China still lacks a consistent intellectual property chapter in free trade agreement. This study analyzes the factors of the formulation of intellectual property rules in China's free trade agreements from three dimensions of “socio-economics”, “interest groups” and “international politics”. Socio-economics factor determines the general position of intellectual property strategy of FTA; interest groups factor highlights the key points of intellectual property strategy of FTA; international politics influences the plan of intellectual property strategy of FTA.
