Equilibrium market share—a measure of competitive strength
将寡头市场建模为非零和博弈，用均衡解中的市场份额衡量企业竞争强度，通过比较均衡与实际份额判断企业增长潜力，为投资策略提供参考。
Abstract If an oligopoly is modelled as a non‐zero‐sum game, then the market shares associated with an equilibrium solution can be interpreted as measuring the competitive strength of the firms. By comparing afirm's equilibrium market share with its actual market share, one can conclude whether the firm has positive or negative growth potential in terms of market share, which has some implications for its investment strategy.
