What are the three factors of production factor supply?

Factor supply is the supply of production factors, and the functional relationship between the supply of production factors and their prices is mainly investigated. There are three main factors of production: land, capital and labor. Accordingly, the supply of production factors can be divided into land supply, capital supply and labor supply. Like general commodities, the supply of production factors is directly proportional to their prices, that is, when the price of factors rises, their supply increases; When the price falls, its supply decreases. The supply subject of production factors is the owner of production factors, and the supply price of factors determines the income of the owner of factors. Stimulated by the maximization of income, factors always tend to flow to those enterprises or industries with higher income. This is the way of resource allocation under the market economy.
