Profitability and market share: A reflection on the functional relationship
分析了PIMS数据库中不同类型企业的盈利能力和市场份额之间的函数关系，发现线性关系拟合不佳，小份额企业在服务市场和原材料市场与大企业一样盈利甚至更优，而超大份额企业往往盈利能力下降。
Abstract The paper analyzes the functional relationship between profitability and market share for type of businesses in the PIMS data base. Although a linear relationship has been imposed in other studies, our result shows that empirically it seems a poor representation of the data. In addition, three observations seem to be most evident. First, small‐share businesses were not per se less successful than larger business units. In the service market and the market for raw or semi‐finished materials small‐share businesses were just as profitable or even more profitable than larger business units. Second, some businesses were ‘stuck in the middle’, which was most evident in the service market but also in the retail and wholesale markets. Third, very large‐share businesses were often less profitable. A critical market share was identified as between 65 and 70 percent. Beyond that level the ROI decreased.
