For an enterprise, profitability is the specific performance of business results in each link, one of the important indicators, and the most direct response to its ability to make profits. Lenovo Group has been on the Fortune 500 list continuously, with its total income increasing and ranking rising, but its profit has not maintained growth all the time. Using descriptive statistics, correlation analysis, Unit root test, Johansen Cointegration Test, Granger Causality Test, and Vector Autoregressive Models (VAR), this paper establishes multiple regression equations to analyze the impact of various factors on its profits from 2000 to 2021 and helps Lenovo Group to improve its profitability while maintaining the continuous growth of total revenue.
