Qualitative and quantitative analysis should be uniform, mutually complementary; qualitative analysis is the basic prerequisite for quantitative analysis, there is no qualitative and quantitative is a blind, worthless quantitative; qualitative and quantitative analysis to make it more scientific and accurate, it It can cause extensive and in-depth qualitative analysis of the conclusions drawn. Quantitative analysis is based on statistical data, the mathematical model and a mathematical model to calculate the object's method of analysis of the indicators and their values. 4, mutual comparison method. It is through economic indicators compared with each other to reveal the difference between the number of economic indicators of the hydraulic motor, the current longitudinal comparison can be either of the above, it can be horizontal comparison among different enterprises in the same industry, but also can be compared with the standard value . By comparing identify gaps. And then analyze the reasons for the formation of gaps. 5, the mathematical model method. In modern management science, mathematical model is widely used hydraulic motor parts, especially in the economic forecasting and management work, because it is not experimental verification, usually by a mathematical model to analyze and predict the results of economic decisions that may arise from. Quantitative analysis of these five hydraulic motors overhaul, ratio analysis is based on trend analysis, structural analysis methods and comparative analysis is an extension of the mathematical model law represents the development direction of the quantitative analysis.
