我国上市公司技术并购绩效的实证研究

技术并购被越来越多的企业认为是实现技术跨越、提高自身核心竞争能力的手段。但目前人们对技术并购的绩效表现并不明确,本文对我国目前技术并购对企业绩效贡献进行了实证研究。文章以2000年到2005年上市公司的并购公告为基础,以其在公开信息披露中称获取某种技术为其并购的意图或意图之一为标准,并进行管理因素"噪音"和再并购因素"噪音"控制,最后选取由41个公司的并购事件组成的一个样本。采用ROA相对值和ROE相对值作为评价基础,对该值并购前一年、并购当年、并购后第一年和并购后第二年的变化进行假设检验。结果显示,技术并购并没有给主并企业的绩效带来普遍贡献。再结合频数分析和描述性统计,发现尽管技术并购的成功率不高,但获得成功的企业可以通过技术并购创造很高的效益。所以,提高技术并购的收益与效率是我国企业在这一领域工作的当务之急。
