There are two kinds of national income: physical form and value form. From the form of value, national income is a net output value, which is divided into accumulation fund and consumption fund, and is actually a value composition. Accordingly, in terms of material form, national income refers to net products, which can be divided into means of production and means of subsistence according to use, that is, material composition.

The material composition of national income is new means of production and new means of consumption. The material composition of national income should emphasize the word "new increase", otherwise it will be wrong.
