Based on CHFS micro data and official macro data respectively, this paper uses entropy weight method Topsis to construct a three-level and more universal financial development index, which proves the positive relationship between financial development and financial fraud through both macro and micro dimensions. At the micro level, this relationship is transmitted through risk appetite and exogenous financing ability, and is more significant in the micro groups of eastern region, low education level, and non-financial practice.
