Mobile finance plays a great role in solving problems of rural finance, such as insufficient physical outlets and excessive high transaction cost. Based on the field survey data of Village A in Sichuan Province, analysis and study were carried out on the development and use of rural mobile finance. The results indicated that the degree of use of rural mobile finance is not high. Mobile finance is mainly used in the young and the middle aged people with high educational level, engaged in non-agricultural industry, and with lower middle income. The business is single and mainly concentrated in shopping and transfer of account.
