Abstract: The finance system of China has undergone great changes since practicing reform and opening policy. However, monopoly exists in the integrated finance system all along, which does harm to the competition among the state-owned banks, joint-stock banks, city credit corporation institutions and foreign banks. There are many factors that result in the monopoly market structure. This paper thinks that the strict market access regulation and depriving pricing are the main reasons. In order to solve this problem, it is urgent for the government to loose the accessing regulations, reform the property right of the state-owned banks and cancel the price regulations so as to promote interest-rate market conduct.
