Equity and efficiency are two basic value choices for the decision making and development of higher education institutions. Dr Zhang's paper is based on game-theory, and in it he analyzes the three ‘parties' of a higher education institution: government, colleges and students. They will pursue their own maximum profit, leading to collective rationalization or collective non-rationalization. Achieving an equilibrium of anticipated equity by adjusting each party’s behavioral strategies is one approach to avoiding collective non-rationalization.
