Since 2005, with the launch of the world's first Peer-to-Peer Lending (P2P) company Zopa, the online lending industry has become a new emerging trend in the global financial sector by directly brokering lending transactions between lenders and borrowers through Internet platforms. In this paper, we leverage a repeated game analysis method to establish the theoretical basis for the development of P2P platforms, and at the same time describe in focus the risks and development trends of the P2P industry in the U.S. and then propose the implications of U.S. online P2P lending regulations for the P2P lending market in Taiwan. We recommend that the relevant competent authorities and regulators should draw a red line for the P2P lending business model to restrict and continuously amend it to adapt to the development of the industry. After the financial legal system of our country has matured, the government can devise financial regulatory policies that differentiates the operating behavior of various P2P lending companies, so that the P2P lending industry can be regulated comprehensively and effectively.
