我国医药制造行业并购绩效研究摘要:随着我国医药行业改革的不断推进,并购能否给医药行业带来良性发展值得关注。本文以2012年发生并购的医药制造行业上市公司为研究对象,从偿债能力、发展能力、经营能力、盈利能力四个方面选取净资产收益率、资产负债率每股收益等12项财务指标,利用因子分析的方法构建并购绩效综合评价体系,研究样本公司并购前一年(2011年)、并购当年(2012年)以及并购后两年(2013、2014年)共四年绩效的变化情况,并得出结论:在研究期内,样本公司的绩效明显高于并购前的公司绩效,且公司绩效是逐年上升的。关键词:医药制造业;并购绩效;因子分析Mergersandacquisitionsperformancestudyinchina'spharmaceuticalmanufacturingindustryABSTRACT:WiththedevelopmentofChina'spharmaceuticalindustryreform,itisworthyofattentionwhethermergersandacquisitionscanbringtothesounddevelopmentofthepharmaceuticalindustry.Inthispaper,ItakeM&aactivityoflistedcompaniesofpharmaceuticalmanufacturingindustryin2012astheresearchobject,selects12financialindicatorssuchasROE,debtratio,earningspershare,etc.fromsolvency,capacitydevelopment,management,profitability.UsingfactoranalysisofempiricalresearchmethodstobuildacomprehensiveM&aperformanceevaluationsystem,researchsamplebeforeM&ayear(2011),acquisitionoftheyear(2012)andtwoyearsafterthemerger(2013,2014)atotaloffourchangesinperformancesituation,andconcluded:Inthestudyperiod,thesamplewassignificantlyhigherthantheperformanceofthecompaniesbeforetheacquisitioncorporateperformance,andM&amakescorporateperformanceincreasedyearafteryear.KeyWords:Pharmaceuticalmanufacturing;Mergersandacquisitionsperformance;Factoranalysis目录摘要................................................................IABSTRACT...........................................................II目录..............................................................III一、引言............................................................1二、文献综述........................................................2(一)国内文献综述..............................................2(二)国外文献综述..............................................3三、企业并购绩效理论概述...........................................4(一)并购绩效及并购绩效评价的概念..............................4(二)并购绩效评价方法的选择....................................4(三)因子分析的数学模型........................................4四、并购绩效评价的指标、样本选取及数据来源..........................6(一)并购绩效评价的指标选取....................................6(二)并购绩效评价的样本选取....................................6(三)并购绩效评价的数据来源....................................7五、并购绩效实证研究及数据分析.....................................8(一)描述性统计分析............................................8(二)KMO和Bartlett的检验.....................................10(三)因子方差贡献.............................................10(四)公共因子碎石图...........................................13(五)旋转后的因子载荷矩阵.....................................14(六)因子得分系数矩阵.........................................16六、实证结论.......................................................20参考文献...........................................................21一、引言随着人民生活水平的提高和对医疗保健需求的增加,我国医药行业在国民经济中占据着越来越重要的地位。在经济增长放缓的背景下,我国医药制造业飞速发展,2011—2014年医药制造行业利润水平略有下降,但是...
