摘 要: 该文以1999~2003年间沪、深两市发生的699起股权转让超过5%的并购事件为有效样本事件,利用生产函数计算出公司并购前后的全要素生产率,并分析了不同并购活动对产出效率的影响.实证研究表明,整体上看,公司股权转让后产出效率得到提高,但对长期产出效率改善缺乏持续性;混合并购使股权转让公司的效率提高,而横向和纵向并购却降低了目标公司的效率.另外,研究还表明,在不同的所有权结构下,公司的产出效率并不存在显著性的差异. Based on the studies of 699 M&A events which sold share over 5% of all that happened in listed companies of China during the period from 1999 to 2003 by measuring the total factor productivity of finn's level, this paper tries to find out different effects on the firm productivity of the target firms in different types of M&A. In general, empirical results show that the target firms' productivity improves after M&A happens, and then decreases. The performance of the M&A finns which belong to the conglomerate acquisitions improves, while the performance of the horizontal acquisitions and vertical acquisitions decrease. There is a marked productivity difference after M&A in different industries, and the results show that there is no significant difference in the finn's productivity in different ownership structures.
