This paper offers a comprehensive review and careful assessment of China's mobile payment business. With broad access, low costs, and reliable transactions, mobile payments are creating a revolution of financial inclusion, changing people's daily lives and commercial business models. This study also confirms that mobile payment improves risk sharing among individuals and increases entrepreneurial opportunities. These mobile payment successes can be traced to three key factors: supply shortages of alternative payment services, a friendly regulatory environment, and recent technological developments. A number of outstanding issues remain, however, including data ownership, data inequality, and regulatory shortcomings.
