In a Command Economy or Planned Economy, the central or state government regulate various factors of production. In fact, the government is the final authority to take decisions regarding production, utilization of the finished industrial products and the allocation of the revenues earned from their distribution.
The government-certified planners come second in the hierarchy. They distribute the works among the labor class, who actually undergo the toiling part of the entire process. China and former USSR and are perhaps two of the best instances of Command Economy. Though many countries now-a-days are switching off from Planned Economy to Market or Mixed Economy, yet nations like North Korea and Cuba are some countries where Planned Economy still exists in full form.
In case of a Command Economy, both state-owned and private enterprises receive guidance and directives from the government regarding production capacity, volume, modes of production and course of their actions. Planned economic system is broadly segregated into two groups – Centralized and Decentralized. The centralized or centrally Planned Economy, as prevalent in former Soviet Union, is a more familiar concept between the two. The decentralized Command Economy, on the other hand, is more theoretical in nature with little or no application in the actual economic spheres.
