The problem of money laundering in the development of inclusive finance can not be ignored. The reason is that by strengthening the risk of inclusive finance, money laundering endangers the stability of the financial system and aggravates the negative effects of inclusive finance. After considering the factor of money laundering, we re-examine the relationship between inclusive finance and economic growth, and find that with the increase of the risk of money laundering, the negative effect of inclusive finance on economic growth is significantly enhanced. Therefore, the development of inclusive finance should strive to be sound in order to avoid the risk of money laundering endangering economic growth.
