Research on the development trend of Harbin's ice-snow tourist market based on the gravity model

The important factors influencing the demand of ice-snow tourist market include the population of source region, economic condition, attraction of tourist destination for the tourists, and distance between the destination and source region, etc. This paper adopts the gravity model to analyze the factors which are difficult for quantization, make quantitative interpretation, and establish the prediction model. The result data demonstrates the validity of the modified gravity model in the prediction of the development trend of ice-snow tourist market.
