A national economy in which the government seeks to determine economic activity largely through a mechanism of central planning, as in the former Soviet Union, in contrast to a market economy which depends heavily upon market forces to allocate productive resources. In a "non-market" economy, production targets, prices, costs, investment allocations, raw materials, labor, international trade and most other economic aggregates are manipulated within a national economic plan drawn up by a central planning authority; hence, the public sector makes the major decisions affecting demand and supply within the national economy.
