本文在西方系统化的并购理论基础上,试图通过引入行业及企业层面的相关变量对近几年(2013年至2018年)A股医药并购事件的短期效绩水平进行评价。通过逐层递进的方式,对“在A股医药行业波动及其收益影响下,医药企业并购决策对市场投资者反应(公告期绩效)的影响”进行了探讨。
本文首先通过对文献综述、企业并购及市场反应理论、企业并购绩效及其市场投资者反应影响因素等做了系统的概念及理论的阐述和总结。
其次,分别通过事件研究法、多元回归分析法对379家企业共428起并购事件进行不同层面(行业层面:市场波动及收益;企业层面:企业规模、负债率、并购规模、企业盈利能力、企业性质、并购前12个月是否存在并购)影响因素条件下,不同并购决策的市场投资者反应实证研究。并对企业并购的相关内外部控制变量和并购市场投资者反应(绩效)的相互关系进行了探讨。为医药并购决策者以及投资人提供参考。
