Based on the panel data of China’s financial service trade export to 24 partners，this paper does an empirical research on the export potential and efficiency of China’s financial service trade by stochastic frontier model. The results show that：the per capita GDP，the distance between the two countries，relative distance and multiple openness，nations whether adjacent with our country all have significant impacts on China’s financial services trade export；our country has a common trade deficiencies with our major trading partners；there a great growth potential in our financial service export. In the study of the efficiency of China’s financial service trade export，we found that trading nations’ economic freedom index，the proportion of the export of financial service trade to total export in services all have significant influences on the efficiency of China’s financial service trade export，the current financial service trade export efficiency of our country is still relatively low.
