Using the data system of 600 MFIs in 85 countries from 2001 to 2014, this paper examines the impact of ownership types of MFIs on their financial performance and outreach.The results indicate that NGOs MFIs do not have different financial performance from For-profit MFIs. In terms of outreach, the average amount of loans issued by the micro-financial institutions is smaller, and the NGOs MFIs socially perform better than other MFI ownership types in satisfying a higher proportion of female borrowers and a large number of customers demand for micro-credit with lower average loan balance. What’s more, the NGOs MFIs play a leading role in achieving the goal of poverty alleviation.In the micro-financial institutions with different ownership types, the micro-financial institutions can better take into account the financial performance and outreach.
