Abstract: The theoretical basis, influencing mechanism and functional effects of free trade areas have changed with the evolution of depth of bilateral free trade agreements and the changes in trade patterns and trade formation caused by GVC Based on the depth evolution of bilateral free trade agreements and its heterogeneity compared to other regional trade agreements, this paper incorporates the theory of corporate property rights into the theoretical framework of free trade areas to form a multidimensional theoretical mechanism between GVC and bilateral free trade areas In addition, a modified gravity model adapted to the development of GVC and the World Banks trade agreement content database are used to conduct empirical analysis to test the theoretical mechanism hypothesis The empirical results show that the depth of the bilateral free trade agreement has a positive impact on the global value chain linkages between member countries; the depth of investmentrelated provisions has a greater impact on the global value chain linkages between member countries than the depth of traderelated provisions; differences of the member countries also influence the effect of bilateral free trade areas on GVC linkage between member countries Differentiating the depth of a free trade area based on the target country is important in the construction of a bilateral free trade area This study will provide some policy references for constructing a highstandard free trade areas network to choose target countries and free trade area model
