Research of Willingness to Use Digital Currency in International Shipping — based on Operations Research Theory

International shipping is an important part of the digital economy. Digital RMB is essential to promote national economic development and paperless development. In this study, SOR theory and perceived value model were integrated to construct an influencing factor model for using digital RMB. The innovation of this paper lies in the use of structural equation model to verify the influence path of assumptions and variables, and analyze the condition configuration that affects willingness to use digital currency from the perspective of factor combination. The empirical results show that the stimulus variables positively affect the willingness to use digital RMB through perceived usefulness. The desire to use digital RMB is negatively affected by perceived risk.
