Corresponding author: LI Da-wei, E-mail: dv78 @ 163.com) Abstract: In order to analyze the equilibrium conditions of competition between two-sided platforms with agent mult-i homing, a baseline model with two-sided network effects was constructed, and by changing the model s assumptions, the conditions under three cases were discussed, including two-sided single-homing, one side mult-i homing and partial mult-i homing. Based on the studies of equilibrium price and market share under the three cases, it is found that mult-i homing has a direct effect on the platforms pricing strategies, and the platform tends to charge mult-i homing agents and provide discounts for single-homing agents. The agent mult-i homing not only influences the equilibrium conditions but also results in thetilt prices in two-sided markets. ey words: two-sided market; mult-i homing; single-homing; price structure; tilt price , , , [ 2] .Hermalin Katz [3] ,(mult-i homing) . . : , ,
