With the development of modern information technology, led by the internet, the finance sector has changed beyond recognition. The internet is not only a channel to promote and sell financial products, but is also deeply involved in financial product innovation, process design, and model transformation. Specifically, changes come from three aspects: first, the reduction of transaction costs and the improvement of transaction efficiency; second, the reduction of mass data collection costs, the difficulty in processing and excavating data; and last, the Internet has broken down monopolies by a small number of financial institutions, bringing more participants into multi-level financial transactions.
