  • The Investment Policy of Large Cities within a Context of the General Trends of Economic Development
  • UDC 332.142:711.433/.438
    The problem of a choice of an investment policy of cities under the conditions of industrial and postindustrial development is considered. It is shown, that the choice of directions and objects of investment depends sufficiently on natural competitive positions of cities and a vector of their development. The preservation of investment policy developed in the course of industrialization and typical for industrial cities leads to retardation of their economic development and exhaustion of resources. As a compromise investment policy it is proposed to develop urban agglomerations and structure of investment objects corresponding to it.
    Keywords: city, municipality, investments, investment policy, agglomeration, industrial development, postindustrial type of development, trend of development.

Under the conditions of ravine formation the cost increases by 10-20 %, under conditions of waterlogging - by 0,2-2 %. In some cities that are built in the permafrost area the quantity of deformed constructions reach up to 50-100 %, in the area of loessial ground - 55-75 %, in the swelling clay area - 45 %, in the saline soil area - 80 %.
