Marginal analysis is to compare two different modes of production and operation: one is to use ordinary production technology or the original technology of the enterprise to operate; The other is to operate after investing in intangible assets, and the profit of the latter is greater than that of the former, which is the extra profit brought by investing in intangible assets; Calculate the proportion of new profits to total profits in each year, and calculate the proportion of new profits to total profits in the life of intangible assets according to the weight of present value of profits in each year, that is, the expected profit sharing rate.

Marginal analysis is an economic analysis method. Marginal analysis is to compare the extra expenditure with the extra income. When the two are equal, it is the critical point, that is, the point where the income of invested funds equals the loss of output.

Mathematical principle

For discrete cases, the marginal value is the ratio of the change of dependent variable to the change of independent variable.

For the continuous case: the marginal value is the derivative value of the dependent variable about the independent variable.

So the meaning of the margin itself is the rate of change of the dependent variable about the independent variable, or the amount of change of the dependent variable when the independent variable changes by one unit. In the study of economic management, the marginal quantities often considered are marginal income MR, marginal cost MC, marginal product MP, marginal profit MB and so on.
