竞争视角下市场占有均衡：理论模型与现实解释

市场占有行为是经济主体的理性行为，市场占有的实现方式有市场竞争与政策约束。文章构建市场占有均衡模型，指出经济主体基于自身的市场占有偏好进行市场占有，并根据市场收益的增减或发展目标的重新设计分别对市场占有偏好进行自发性纠正、战略性纠正，从而形成新的市场占有均衡。市场占有均衡因对手的竞争反应的差异而表现出不同的均衡状态。基于市场占有均衡模型，文章以新的角度审视了公共产品供给不足、厂商恶性竞争及国企改革等经济现象。

A study on the equalization of market share under the perspective of competition--based on the model construction and realistic explanation

As the rational behavior of economic entities, market share is achieved by the way of competition and policy. From the balanced model of market share, this paper studied that the economic entities occupy the market based on the preference for market share, and adjust the preference for market share according to the revenue and goal’s changing, which forms the new equalization of market share. Differences on the competitor’s reaction will lead to the different equalization of market share. Based on the balance model of market share, the paper made a new explanation on the economic phenomena, such as the shortage of the public product,vicious competition and the state-owned enterprise reform.
