This paper examines the impact of the policy on eliminating the ratio of foreign shareholding in banks in a mixed oligopoly *** analytic results show that state-owned banks should encourage privatisation along with an increasing proportion of the domestic share in multinational ***,we argue that the increase in domestic stockholding of multinational banks raises domestic private firms’profits but decreases their social welfare in the deposit *** results of numerical simulation show that when the quantity of private banks is fixed,foreign banks tend to enlarge their stake and strengthen their controlling power.
