防范化解重大风险是实现高质量发展的前提.在并购重组市场化改革进程中,并购估值失实问题日渐受到资本市场各方关注.本文以近年来迅速发展的并购重组市场为背景,考察并购资产评估偏差是否加剧了股价崩盘风险,并从信息不透明视角和代理问题视角分析其作用机制.基于2009-2017 年沪深A股上市公司的股权收购资产评估数据,研究表明,并购资产评估偏差与股价崩盘风险显著正相关,而资产评估机构的高声誉能够抑制这一正向关系.机制分析表明,并购资产评估偏差增大了公司和外部投资者之间的信息不对称.异质性检验表明,并购资产评估偏差与股价崩盘风险的正向关系在两权分离度较高时更显著,在股权制衡度较高、公司外部治理较强时则减弱.本文丰富了公司并购与股价崩盘风险的研究,为并购资产评估偏差的经济后果提供了新的实证证据,并且提醒监管方和投资者重视资产评估信息质量,对于防范化解金融风险具有一定启示.
Asset Appraisal Bias of M&A and Stock Price Crash Risk
To Prevent and defuse major risks is a prerequisite for realizing high-quality development.In the process of marketization reform of merger and acquisition(M&A)market,asset appraisal fraud is increasingly receiving attention from all sectors in the capital market.Based on the Chinese M&A market that has developed rapidly in recent years,this paper examines whether the M&A asset appraisal bias increases the stock price crash risk,and analyzes its mechanism from the perspective of information opacity and agency problem.Using asset appraisal data from stock acquisitions by A-share listed firms in Shanghai and Shenzhen stock market during 2009-2017,we find a positive relationship between M&A asset appraisal bias and crash risk,and this relationship is weakened when the appraisal institution has a higher reputation.Mechanism analyses show that the appraisal bias increases the information asymmetry between firms and investors.Cross-sectional analyses show that the positive relationship between appraisal bias and crash risk is more pronounced with a higher separation of ownership and control,but less pronounced with a higher level of equity balancing and stronger external corporate governance.Our research enriches the literature of M&A and stock price crash risk,provides new evidences for the economic outcomes of asset appraisal bias,reminds regulators and investors to pay attention to asset appraisal quality,and provides enlightenment on preventing and defusing financial risks.
