Analysis of enterprise internal financial report. Many times, the analysis of internal financial reports of enterprises needs multi-dimensional drilling and tracing, so as to find the crux of the problem and help enterprises improve management and achieve the expected goals. For example, for the income statement of the same period, it is necessary to analyze the external financial statements of the enterprise at the same time. Most commonly, we investors may want to invest in a company. Then before that, we need to look at the basic situation of this company. At this time, we get more external data. Compared with the internal analysis of the company, it can be concluded that the amount of data and information comes from external information. The main methods of financial analysis, generally speaking, there are four main methods of financial analysis: 1. Comparative analysis: explain the quantitative relationship and difference between financial information, and point out the direction for further analysis. This comparison can be compared with the actual plan, the current period and the previous period, and also with other enterprises in the same industry; 2. Trend analysis: it reveals the changes in financial status and operating results, their causes and nature, which is helpful to predict the future. The data used for trend analysis can be absolute value, ratio or percentage data; 3. Factor analysis: in order to analyze the influence of several related factors on a financial index, the method of difference analysis is generally adopted; 4. Ratio analysis: Through the analysis of financial ratio, we can know the financial status and operating results of enterprises, often with the help of comparative analysis and trend analysis. The above methods overlap to some extent. In practical work, the ratio analysis method is the most widely used. ? Classification of financial ratios?
