There are four types of markets: perfect competition market, complete monopoly market, monopolistic competition market and oligopoly market.

Among them, the perfect competitive market: the perfect competitive market in the economic sense is an ideal model. Because there are countless producers and consumers, the output of each producer and the demand of consumers can be ignored, and the behavior of each participant will not affect the whole market. Agricultural products market and stock market can approximately meet the assumption of perfect competition market.

A perfectly competitive market has the following characteristics: (1) The manufacturer is the price receiver; (2) Manufacturers are completely free to enter and leave this industry; (3) All manufacturers produce products with the same characteristics; (4) Both manufacturers and consumers have complete information about the market.

Complete monopoly market is an extreme market type relative to complete competition market. Complete monopoly market is also called pure monopoly market, which is generally called monopoly market. The word monopoly comes from Greek, which means "one seller", that is, one person controls the whole market supply of a product. Therefore, a complete monopoly market refers to a market type with only one supplier.

Monopolistic competitive market: it is a market that is both monopolistic and competitive, neither completely monopolistic nor completely competitive. This is a similar but different market.

Oligopoly market means that a few enterprises control the whole market, and the goods they supply account for the largest and most important share of this market. Also known as oligopoly manufacturers, it refers to the market structure in which a few manufacturers control the production and sales of products in the whole market. The typical feature of this market is that manufacturers' behaviors influence each other, so manufacturers should consider the reaction of competitors in their decision-making. According to product characteristics, oligopoly market can be divided into pure oligopoly industries and different oligopoly industries. In pure oligopoly industry, manufacturers produce undifferentiated products; Manufacturers produce different products in different oligopolistic industries. According to the behavior of manufacturers, oligopoly market can be divided into different types of collusion and independent behavior. Oligopoly industry is considered as a common market organization.
