The competition between small and middle enterprises is regarded as Cournot-Bertrand competition model.

As a result, if merging to monopoly is precluded by anti-trust concerns, and there is two-stage staggered competition within a merged firm and Cournot competition between the merged firm and unmerged firms, then a preemptive merger that is profitable can induce the occurrence of sequential horizontal mergers.

In this paper,we analyze merger incentives and merger effects caused by the managerial incentives based on a linear combination of corporate profits and revenues, and establish a two stage game model of endogenous mergers under Cournot competition in an oligopoly industry with substitute products.

An evolutionary game model of Cournot competition is studied.

A two-level supply chain model with one manufacturer upstream and two retailers engaged in Bertrand competition downstream was developed to study the factors influencing supply chain members optimal expected profits and the sensitivity to cost information sharing.

Under the condition of an upper stream manufacturer and two distributors who sell different products, hold private demand information and carry out price-based Bertrand competition, the paper establishes a three-stage game theory model, gets equilibrium result and puts forward such a tactics as sharing demand information between manufacturer and distributors.

This paper analyzes the licensing strategies of patent-holding firms with cost-reducing innovation protected by a patent proprietary in a differentiated Cournot oligopoly market where two of firms has cost-reducing substitute innovation protected by a patent proprietary.

Licensing strategies in a differentiated Cournot oligopoly;

Cournot model is employed to analyze multi-period Nash equilibrium strategy of suppliers for hydrothermal power system in power pool.

The Cournot model of economics was adopted in considering of two different incomplete information of company cost functions: asymmetric incomplete information and symmetric incomplete information.

Cournot model was used to simulate wholesale electricity market,and equilibrium results were derived after vertical integration between a grid company and a generation company.
