The motive organization of social production are the needs of people. In the economic literature, there are several interpretations of the requirements. The most common approach is the following: the human need - a state of dissatisfaction, or needs, which it seeks to overcome. There are other points of view - this is deliberate requests or needs anything, objectively necessary living conditions, etc.

Need - it's strong desire to get any benefit (food, clothing, shelter, etc.), or to avoid something undesirable (opastnosti, loneliness, shame, etc.)

The need - is a need to adopt a specific shape, depending on the level of development of society and the individual.

For example, all the people to sustain their livelihoods are in need of food. Some people have a need for the acquisition of pasta and smoked meat, others do not eat meat and pasta, and satisfy their need for food with other foods.

Only when there is awareness of the needs of the motivation to work. In this case needs acquire specific shape - economic interest.

Economic interest - a form of manifestation of economic needs.

Since human needs are diverse, so they need to be classification. You can select the following classification criteria:

· On the importance (primary or biological and secondary, or social)

· On the subjects (individual, group, collective, community);

· On the project (material, spiritual, ethical, aesthetic);

· On the feasibility of (real and ideal);

· By area (needs work, communication, recreation, and economic);

· The nature of satisfaction allocate economic needs (the latter include the part of human needs, which are used to meet the limited resources and the necessary production) and non-economic needs (those that can be met without the production of, for example, the demand for water, air, sunlight and etc.).

Classification of human needs, taking into account the stages of social development offered an American scientist Abraham Maslow (Maslow pyramid)

· Physiological needs (food, water, clothing, shelter, procreation);

· The need for security (protection from enemies and criminals, help with illness, protection from poverty);

· The need to belong to social groups, social relationships and communication (friendship, love, affection, etc.);

· The need to respect (from others and self-esteem);

· The need for self-development (in the improvement of all the possibilities and abilities).

People's needs are not static, they evolve in the evolution of human society. German scientist E. Engel (XIX c.) Established a link between the incomes of the population and consumption patterns, known as Engel's law. Its essence is that the higher the quality of people's lives, the less their demand for food products.

Simultaneously, the demand for manufactured consumer goods, and a further increase in the standard of living of people are increasing purchases of goods and services increased
