This paper constructs the money demand function including the variable of electronic payments while adopting the Autoregressive Distributed Lag (ARDL) bounds testing approach to investigate the relationship between electronic payments and money demand in China. The empirical results show that there is the cointegration among the variables in the constructed function with stability, and the e-payment variable is negatively correlated with the demand for money. According to the findings of this paper, in the long run, for every 1 percent increase in the e-payment variable, the demand for M1 will decrease by approximately 0.01 percent. In addition, the money demand function that contains the e-payment variable performs better than the one that does not in the forecast evaluation.
