With the vigorous development of digital technology, more and more enterprises realize the importance of digital transformation. Data has also become one of the enterprise assets. Through modern information technology, enterprises have improved their ability to collect and integrate data. Then the comprehensive data information is analyzed to contribute to business forecasting and enterprise management. This paper takes the customer data from the TIC insurance company as an example. It uses statistical analysis methods to mine the data, such as descriptive statistics, the Pearson chi-square test, the nonparametric test, K-means clustering, and binary logistic regression prediction. Analyze and forecast customers who may purchase RV insurance.

In this paper, we examine the impact of Covid-19 on the Chinese logistics industry, using both qualitative and quantitative analysis to examine the performance of the top five logistics companies in the months following the initial outbreak in early 2020. The top five companies are Shunfeng, Yuantong, Zhongtong, Shentong, and Yunda. Using a linear regression model and a questionnaire of 251 individuals, we analyze the strengths and weaknesses of the top five companies. We then conclude with our financial recommendations for the five companies, based on our analysis.

Recently, Shake Shack, a leading brand in the high-end overseas Western fast-food industry in China, opened its first store in southwest China in Chengdu, intending to enter and expand the market in southwest China. This paper mainly studies the first store of Shake Shack in Southwest China, which was established in Sino-Ocean Taikoo Li, Chengdu City, Sichuan Province, and explores the brand competitiveness of Shake Shack in Southwest China and the possibility of its future expansion. Based on SWOT theory, this paper analyzes the strengths, weaknesses, opportunities and threats of Shake Shack and its competitors in the same industry through literature analysis, case analysis, comparative analysis and data analysis. This paper finds that Shake Shack can quickly open up the channel with consumers, occupy the local high-end American simple meal market, and show other enterprises a new idea of "combining Chinese and Western" by relying on various resources provided by Chengdu, which shows its strong competitiveness. However, there are still some major obstacles to its expansion in the whole southwest market.

Cooperative game theory is concerned with exploring schemes for allocating payoffs among rational participants in coalitions and has produced several solution designs due to the different emphasis on criteria such as stability and fairness, but this theory has not been widely applied in the field of portfolio selection. In this paper, we explore further applications of the solution concepts of cooperative games based on the model of optimal portfolio selection developed in previous studies, which is modelled in a static form of a non-cooperative zero-sum game between investors and the market and a cooperative game between investors. We propose a risk modified Shapley value based on the tradeoff between return and risk in the financial market based on the Shapley value, and the performance of this solution shows an evident improvement. We also introduce some other solution concepts of cooperative games and give an approach to construct a nucleolus-based portfolio using Maschler's scheme to compute the nucleolus, and the results demonstrate that the allocation schemes based on the cooperative game theory perform well.
