摘要: 在我国促进产业整合升级以及上市企业并购重组热情不断高涨的大环境下,国内资本市场出现了新一轮并购重组浪潮;与此同时,我国上市公司并购溢价的水平呈现出快速提升趋势,高溢价并购的不确定性和经济损失的潜在性一旦被市场察觉就可能带来股价的下跌。企业高溢价并购是否会导致股市“过热”,从而引发股价崩盘风险的发生,这是资本市场关注的重点问题。站在微观角度对2008-2013年有过并购交易的A股上市公司进行分析,观察企业高溢价并购对股价崩盘风险的影响,并在“代理冲突”与“管理者过度自信”层面分析其内在的作用机理,发现企业高溢价并购与股价未来的崩盘风险存在着显著正相关性,导致二者存在正相关性的主要缘由为管理者过度自信而非股东与经理人之间的代理冲突,高管过度自信的分析结论更具有解释力。.

Abstract: Under the environment of rising enthusiasm for promoting the upgrading of the industrial integration and mergers and acquisitions(M&A) of listed companies in China, domestic capital market starts a new round of M&A wave. At the same time, premium M&A level of listed companies in China shows a rapid upward trend, the significant uncertainty and high economic loss potential of high premium M&A may bring fall in stock price once they are perceived by the market. Whether high premium M&A would lead to the stock market overheating, and cause the occurrence of stock price crash risk, is the focus of attention of capital market. From the micro point of view, the article analyzes A share listed companies which have experienced M&A in 2008-2013, observes the impact of high premium M&A on stock price cash risk, and analyzes the internal mechanism from “agency conflict” and “managerial overconfidence”, finding that high premium M&A shows a significant positive correlation with future stock price crash risk. The main reason for the positive correlation between the two is the “managerial overconfidence” but not the “agency conflict” between shareholders and managers, and the analysis conclusion of “managerial overconfidence” is more explanatory.

Key words: high premium mergers and acquistions;stock price crash risk, agency conflict, managerial overconfidence
