This paper analyzes the optimal interest rates and project screening strategies for online lending platforms. The transaction process of online lending platforms is first summarized, followed by the construction of a model of the optimal interest rates and project screening strategies for the platforms. The optimal strategy of the model is solved for and analyzed, along with the impact of factors such as platform commission fees and screening costs. Numerical examples are then applied to validate and explain theoretical results. Our results indicate that: (1) the optimal interest rates on online lending platforms equalize borrowing costs for borrowers with external borrowing costs; (2) when the screening ability of online lending platforms attains certain value, an optimal screening strategy exists and is influenced by factors such as interest management fee and cost screening coefficients; (3) proper interest management fee can not only encourage online lending platforms to intensify screening, but also improve their profitability. These results reflect theoretical and applied values of researches on interest pricing of financial information intermediaries and the prevention of moral hazards.
