Abstract: Insufficient capital supply in rural financial markets has restricted the development of Chinas rural economy. By game analysis， we found rural financial institutions cant solve the sustainable funds supply with governments subsidies. But， asymmetric HawkDove game results showed that the greater of the asymmetric intensity between large commercial banks and new rural financial institutions (game participants)， the more they will tend to cooperate. For them， the capital and the farmers information was asymmetric. We found the cooperative supply probability is positively related to the synthetic asymmetry of game participants. And it has evolutionary stability for the participants to select cooperation with the probability. Therefore， we must rationally promote the cooperation between large commercial banks and new rural financial institutions in order to ensure the sustainable development of rural financial markets．
