The basic economic task of functioning of every PTS consists in implementation of the planned tasks of the allied value taking into account geographical position of district, transport terms, advantage of exploitation of resources, raw material, energy, labour, and also decision of defensive tasks.

The performance of basic economic objective results in specialization of every economic district on those industries of production, what in him can be developed most full and advantageously, including all necessary industrial, power and transport links. An exchange between districts is limited to strictly the necessary amounts of products at the waiver of superfluously distant and meetings transportations. Every district carries out complex development of economy on the territory for the most complete satisfaction of local production and consumer needs due to the local sources of raw material and energy.

A scientific and technical policy is individualized on economic districts. The greatest efficiency is arrived at by the combined technological processes at processing of raw material, receipt of energy, use of labour and equipment, resulting in creation of district production combines and production-territorial complexes.

For every economic district three category of productions is set: district value (products are consumed into an economic district); inter-district value (for the group of economic districts); all-union value, and also the most areas of sale.

Development of every district is carried out in such form, instrumental in financial and cultural development of all nationalities of country.

By a key concept in the theory of the economic districting of N.N. Kolosovskogo was concept of energyproduction cycle, which "all aggregate of production processes, developed in an economic district on the basis of combination of this type of energy and raw material of primary forms — booty and ennoblement of raw material to the receipt of all types of the prepared products, which it is possible to get in place, was understood under, coming from the requirements of approaching of production to the sources of raw material and requirements of the complex use of all of the tools of raw material and power courses of this type".

Creation of theoretical bases and method of the economic districting decided three basic problem. The first consisted of mastering of new sources of raw material and energy in the east districts of country and development of heavy industry, that answered the political task of providing of industrial superiority the USSR and decision of problem of basic industrial products. The second problems consisted in creation of the rational system of the territorial planning, providing the maximal use of comparative advantages of economic districts and minimization of transport costs by the planned tasks. The third problems was creation of single informative and intellectual basis for the co-ordinated actions of thousands of workers of the planned organs in a center and on places on development and control after implementation of the planned tasks.
