(2) Educational services provide a special use value, which is not essentially different from that provided by other commodities. Therefore, the services provided by education are commodities, and educational services are commodities.
(3) The characteristic of educational service is that educational labor is not a thing, but an active labor or service as a service. This kind of service or service itself is valuable and is exchanged in the market. It has no essential difference from commodities in material form and other forms, but it is different in form.
(4) The essence of the relationship between the sale and purchase of educational services is the labor force of the material production department cultivated by education, or the labor ability of the labor force. As a buyer, education service needs the investment of education funds to cultivate the labor force, that is, the education cost, that is, the production cost and reproduction cost of labor ability, which can also be called the education cost and learning cost. The value of the labor force trained by education increases with the improvement of the education level of the labor force, that is, the increase of education cost. As a seller, educational services put all kinds of labor trained by education into the labor market for owners to choose and hire. The labor force with different education level and working ability has different prices, that is, different wage levels.
