在本文中，我们开发了一个过程模型的市场份额，企业利润。特别是，我们指定的平均价格和平均成本方程作为上一年的市场份额的位置，市场份额的变化，环境条件，以及环境条件与滞后的市场地位和市场份额变化变量的相互作用的函数。我们估计这些方程使用PIMS数据后，控制不可观测的因素。我们的研究结果表明，具有高市场份额的企业不会获得额外的市场势力利益，除非他们在几乎没有买方势力的环境中运营。相反，环境因素和市场份额的变化对价格和成本的影响最大。对与企业利润最大化相关的市场份额的分析表明，对于我们样本中的大多数企业来说，市场份额的稳步增长并不总是与利润的增长相关，这证明了“更多的市场份额并不总是更好”这一命题。"
In this paper we develop a process model relating market share to firm profits. In particular, we specify average price and average cost equations as a function of previous year market share position, changes in market share, environmental conditions, and interactions of environmental conditions with the lagged market position and market share change variables. We estimate these equations using PIMS data after controlling for unobservable factors. Our results suggest that firms with high market shares derive no extra market power benefits except if they operate in environments with little buyer power. Instead, environmental factors and changes in market share most strongly influence price and cost. An analysis of the market share associated with maximal firm profits indicates that for the majority of firms in our sample steadily increasing market share does not always associate with increasing profits, giving credence to the proposition that "more market share is not always better."
