Market economy is an economic system in which economic agents (companies, banks, service providers, etc.) can act with little governmental interference. It is a typical system of the capitalist economy.
Planned economy is an economic model in which the state controls the economy in the country, in this case most of the existing companies are state owned, ie state properties.
