Forecasting of Provincial Tourist Population based on Grey Neural Network

In this paper, the data set of the number of tourists in Shandong Province from 1990 to 2019 is obtained through the China Statistical Yearbook, and the number of tourists in Shandong Province is fitted and predicted by the time series model, gray model and gray-BP neural network combination model. The experimental results obtained prove that the improved gray-BP neural network combined model provides most ideal results.
