Description基于中国人口老龄化加速、目前人均医疗支出偏低和国内医疗器械企业以中低端产品

为主的局面,中国的医疗器械行业正面临着巨大的发展机遇,投融资活动将迎来爆发式增

长。 在此背景下, 医疗器械企业的估值研究对投融资双方都有较大的意义。

我们假设医疗器械公司的产品差异度对其公司的估值有正面影响。

产品差异度定义为:该产品区别于其他竞争性产品的独特性,由以下六个方面构成:

产品唯一性水平、先进性(器械类别、优秀国产医疗设备个数、产品的专利化程度)、利润

边际和其市场容量,并对此用 12 个指标做出了定量的估计。本研究主要的数据来源是上市

的医疗器械公司,因为这些公司的相关数据取得比较容易且数据客观性较强。我们使用一

般回归分析测量产品差异度与公司估值之间的关系。在得出正面的回归结果之后, 我们采

用双重差分分析(DID)方法,验证实际情形下新产品相关信息发布对公司股价波动的影响。

根据回归分析结果:

1、 “产生营收的产品唯一性水平”和“边际利润”与市值有显著相关性: 说明医疗器械

类企业确实是核心产品驱动发展的, 产品唯一性程度高(已剔除那些已逐渐被市场淘汰的

产品) 说明市场定价能力强, 边际利润率高,盈利能力强, 进而对公司估值形成正面影

响。

2、 “”净利润“和”“互联网概念”与市值也呈现显著相关性。净利润的相关性是显而易见

的。互联网概念的相关性体现了互联网+医疗成为近几年市场的风口。

3、 其他一些指标未呈现明显的相关性,有可能是因为我们的数据量太少引起的, 也

有可能还有其他未在我们考虑范围内的因素导致的,也可能是因为中国目前的股票市场还

未到达半强式有效市场。这可能对其他行业的影响也是如此。

在后面进行的实证分析中, 除个别情况外,我们发现公司重磅新产品相关信息的发布

基本上对公司之后 1-30 个交易日的股价起到了较明显的推动作用。

This study investigates the performance effects of cross-industry mergers and acquisitions (M&A) using a sample of firms listed in China’s Growth Entrepreses Market (GEM). Compared to firms listed in the Shanghai and Shenzhen Stock Exchanges, firms listed in the GEM are much smaller and tend to derive the majority of their revenues from a single industry. I first analyze the motives for firms listed in the GEM to engage in M&As and propose a set of factors that may influence their likelihood of M&A activities. Using data on 55 cross-industry M&As between January 1, 2012 and December 31, 2016, I find that investor generally responded positively in short-term, as indicated by the positive accumulated abonormal returns over the first five trading days following the announcements. Meanwhile, I found no evidence that investors benefited from cross-industry M&As in long-term over three years after the event. Further analysis suggests that the short-term effects of cross-industry M&As by GEM listed firms were influenced by the target firm’s market valuation, whether the M&A was paid by cash, the amount of the payment, and the degree of difference between the acquiring firm’s and the target firm’s industries. These findings have important implications for the investors and senior executives of firms listed in the GEM.
