How does the economy depend on the volume and focus of our needs?

There is such a thing as division of labor. At the level of one enterprise, it is worth talking about the division of labor between employees, that is, the organization has departments, departments, departments, groups and the task of each employee is to perform a small range of responsibilities depending on the general goals of the group and on the goals of the organization. At the country level, it is more likely to talk about a regional division of labor, for example, the need for heating a home can be satisfied by supplying heat, which depends on gas production (Yamalo-Nenets Autonomous Okrug) and so on. In a market economy, demand creates supply, which is exactly why it directly depends on these factors. The orientation of needs forms a certain market for goods and services, and the volume of needs can only satisfy the optimal number of manufacturers, suppliers or contractors in accordance with the volume of needs.
