Answer:
Under the communist theory, the supply of goods and services is determined by community central planning. In a communist system, the government or a central planning agency is responsible for determining the quantity of each good and service that should be produced and distributed to meet the needs of the population. This is typically done through a system of central planning, in which the government or planning agency sets production targets and allocates resources accordingly.
One of the main goals of communist theory is to create a more equal distribution of wealth and resources, and central planning is seen as a way to achieve this goal. By centrally planning production and distribution, the government or central planning agency can ensure that resources are allocated in a way that meets the needs of the population, rather than being driven by profit or other market forces.
In contrast to a market-based system, where supply and demand are the main determinants of production and prices, the supply of goods and services in a communist system is not determined by the invisible hand of the market. Instead, it is determined by the government or central planning agency, which aims to ensure that the needs of the population are met in a fair and equitable manner.
