【摘要】 我国证券市场的发展虽刚刚起步,但已具备了较强的“资本运营”理念,在这种理念的指导下,我国上市公司资产重组的数量以惊人的速度发展着,并涌现出不少成功的重组案例。但是,上市公司资产重组的绩效如何却并不清楚,争论颇多。在社会资源配置效率方面争论的焦点之一是:在众多的上市公司资产重组案例中,股价是否显著的受到影响?有关的信息知情人是否利用了内幕信息进行证券交易?股东能否从重组事件中获得正的超常收益?在微观效率方面争论的焦点之一是:大量且频繁发生的上市公司资产重组活动,是否真的提高了有关公司的真实经营效率?这些问题,都需要从理论上和经验上对其做出解释。本文将从这一意义上对我国上市公司资产重组的绩效进行实证研究,以期做出客观的评价,为证券市场监管机构更好的规范资产重组行为提供建议。 本文首先在对资产重组理论和国内外资产重组绩效的实证研究成果总结的基础上,总结了我国上市公司资产重组的阶段特征,剖析了我国上市公司资产重组中存在的问题及其成因;接着引出本文的重点,即实证研究部分。以2002年沪市A股发生资产重组的上市公司为原始样本,搜集整理了2002年沪市A股发生的股权转让、收购兼并、资产剥离、资产置换四种类型的重组事件,共计795起,涉及上市公司399家,分别采用事件研究法和会计研究法,从我国上市公司资产重组的短期股票市场反应和对公司业绩的长期影响两方面入手,对上市公司资产重组绩效进行了实证分析;然后根据实证研究结论提出了完善我国上市公司资产重组交易市场的政策建议;最后对全文进行总结,指出本文研究的局限性,并提出了后续研究建议。 本文的主要创新之处有:(1) 分别采用事件研究法和会计研究法对我国上
