Except if you understand what the command economy is then you must understand this:

A state-capitalist country is one where the government controls the economy and essentially acts as a single huge corporation, extracting surplus value from the workforce in order to invest it in further production.[3] This designation applies regardless of the political aims of the state, even if the state is nominally socialist.[4] Some scholars argue that the economy of the Soviet Union and of the Eastern Bloc countries modeled after it, including Maoist China, were state capitalist systems, and Eastern and Western commentators alike assert that the current economies of China and Singapore also constitute a mixture of state-capitalism with private capitalism.[5][6][7][8][9]
