Methodological approach to the market structure type identification (using the example of the fish production market of Primorskii krai)

The article is devoted to the search of a way to solve one of the fundamental problems of economic analysis of industrial markets, that is, the identification of the market structure type, lying at the interface of oligopoly and monopolistic competition or oligopoly and monopoly. It is proposed to conduct such an identification procedure on the base of using the instruments of L. Zadeh’s possibility theory. The proposed approach has been evaluated on the example of the fish production market in Primorskii krai.
