In recent years, the ice and snow tourism industry has developed rapidly, which plays an important role in boosting regional economy. The prosperity index of the ice and snow tourism industry was compiled, and the early warning model of the ice and snow tourism industry in Heilongjiang Province of China was built, which was taken as a comprehensive scale to observe the fluctuation of the ice and snow tourism industry. Combined with the current economic situation, the composite index, the situation of the industry and the turning point of the industry cycle volatility are analyzed, to determine the situation and trend of the industry volatility. This can provide reference for the policy formulation of the ice and snow tourism industry in Heilongjiang province and the micro-management of tourism companies.

When economic entities are facing severe tests, the live broadcast sale is booming with its own advantages. However, at the same time, it is also facing a series of problems such as lack of anchor credit, numerous fakes, and weak platform supervision. In the process of quantitative research on live delivery of goods, various difficulties will be encountered, such as information asymmetry between subjects and untrue data sources. Therefore，This paper establishes an evolutionary game model between the anchor ,the consumer, and the anchor and the live broadcast platform, and explores its equilibrium state, and performs numerical simulation analysis on this basis. Discuss and analyze the main factors that influence the strategic choice of the evolutionary body, deepen the understanding of the live broadcast industry, so as to promote the correct understanding of the live broadcast industry and related fields, and put forward reasonable and effective suggestions and countermeasures for regulating the development of the live broadcast economy.
