Based on the research of tourists' functional requirements for WeChat guide program, the common primary and secondary functions were selected as the research objects through the use of multi scenic spot guide programs. Firstly, the Pareto method was used to screen out the important functional requirements in the minds of tourists, and then the A-Kano model (An Analytical Kano Model) was used to analyze the satisfaction of tourists to the functional requirements, and the weight score was used to quantitatively evaluate the hierarchy of needs of each function of WeChat guide program. The demand attribute classification and priority ranking of each function of WeChat guide program in the Sui and Tang Dynasties of Luoyang City were obtained, and verified by the new function configuration. The WeChat guide program tourist demand research method proposed in this paper is in line with the behavior and habits of tourists in China, and can effectively improve the user satisfaction of Chinese tourists.
