摘要:

对资产重组样本公司进行事件收益分析后发现, 我国上市公司在资产重组过程中出现了非常明显的短期累计超常收益, 但不同的重组方式之间产生了截然不同的重组绩效。同时, 样本公司累计超常收益的大小, 受到样本公司自身的经营业绩以及流通股规模的影响, 相对而言, 业绩较差公司和流通盘较小公司的反应更为强烈, 出现了累计超常收益的较大波动。

关键词: 资产重组, 绩效, 事件收益分析, 上市公司

By applying the event study methodology to the sample companies this paper expounds that apparent short term CAR emerges in the listed companies during the course of asset restructuring.The amount of the sample companies' CAR is influenced by its own business performance and the scale of the float.Roughly speaking, the companies with poor business performance and small float caps respond more strongly and end up with greater CAR fluctuation.

Key words: asset restructuring, perfomance, event study methodology, the listed companics
