In economics, market structure describes the state of a market with respect to competition.

There are two kinds of market structures that are usually discussed: perfectly competitive market structure and imperfectly competitive market structure. Perfectly competitive market structure is an ideal state of a market in which the competition amongst the buyers and sellers is likely to be perfectly balanced. The imperfectly competitive structure is quite identical to the realistic market conditions where some monopolists, oligopolists, and duopolists exist and dominate the market conditions.
