【摘要】：本文基于战略群组理论深入分析了企业市场份额与盈利能力的关系,并指出当市场需求及企业战略均具有较强异质性时,不能简单地使用行业市场份额来解释或预测企业的盈利水平,而必须考虑行业的内部结构。在对我国制药业上市公司进行战略群组划分后,使用固定效应模型对研究假设进行了回归检验。结果表明,企业在战略群组内的市场份额对其盈利能力有显著的正向作用,而企业在全行业的市场份额则不具有这种正面作用;群组内份额才是真正影响盈利水平的变量。本文还通过改变样本范围、改变变量控制方法进行回归,均得出了一致结果,增强了研究的稳健性。结论表明,战略群组是一种重要的行业内部结构,对企业的研究不应把行业看作单一的样本背景,而应结合行业内的群组结构进行更深入的分析。
[Abstract]:Based on the strategic group theory, this paper analyzes the relationship between enterprise market share and profitability, and points out that when market demand and enterprise strategy have strong heterogeneity, The industry market share should not be used simply to explain or predict the profit level of the enterprise, but the internal structure of the industry must be considered. After the strategic group division of the listed companies in pharmaceutical industry in China, the regression test of the research hypotheses is carried out by using the fixed effect model. The results show that the market share of the enterprise in the strategic group has a significant positive effect on its profitability, but the market share of the enterprise in the whole industry does not have this positive effect, and the intra-group share is the real variable that affects the profit level. By changing the sample range and variable control method, the same results are obtained and the robustness of the study is enhanced. The conclusion shows that strategic group is an important internal structure of the industry. The study of enterprises should not regard the industry as a single sample background, but should combine the group structure of the industry for more in-depth analysis.
