In order to evaluate the predictive ability of network search data of daily sampling frequency for monthly tourist flow, this paper predicts the monthly tourist flow of Chongqing, China. In consideration of the inconsistency of sampling frequency of network search data and tourist flow data, an autoregression mixed data sampling model (AR-MIDAS) is constructed for prediction to avoid the loss of information. This paper adopts factor analysis technology to extract the characteristic information

... ontained in the consumer search data related to Chongqing tourism, and then puts the obtained comprehensive factor into the model for a prediction experiment. The research results show that AR-MIDAS model can improve the precision of monthly tourist flow prediction better than ARIMA and MIDAS prediction techniques. The research results can provide necessary reference for scientific decision-making of tourism related departments.
