This book addresses internet finance, a concept coined by the authors in 2012. Internet finance deals specifically with the impacts of internet-based technologies - such as mobile payments, social networks, search engines, cloud computation, and big data - on finance. Typical examples of internet finance include third-party and mobile payments, internet currency, P2P lending, crowdfunding, and use of big data in finance. Internet finance is highly popular in China and has been one of the most hotly discussed topics in the past year, so much so that Chinese Premier Li Keqiang even made its healthy development a policy priority in his 2014 state of the union address. This book, as a detailed report on internet finance in China, provides the first systemic review of internet finance both as a concept and as a blooming industry. Internet finance is still in its infancy, and this book is designed to be more than a review: it seeks to inspire readers from around the globe to join discussions on this topic. At the same time, it will help readers better understand the status quo and development of China's financial system and policy.
