With the high-quality development of the economy, the competition among high-tech enterprises is becoming increasingly fierce. Enterprises need to discover and solve problems through financial analysis to improve their competitiveness. Traditional financial analysis only focuses on the analysis of financial data, which can no longer meet the needs of the ever-changing market environment. In contrast, the Harvard analysis framework adds analysis of non-financial data on the basis of financial analysis, which can better help companies understand their competitive advantages and disadvantages. Therefore, this paper takes Xiaomi as the research object, uses the Harvard analysis framework, and conducts financial analysis from four dimensions: strategy, accounting, finance, and prospects. It aims to comprehensively reflect the overall operating conditions and development trends of Xiaomi, and on this basis, puts forward some suggestions for the development of Xiaomi.
