中国的医疗美容行业萌芽于80年代公立医院的整形科室，随着经济的快速增展，医疗美容行业也在经历漫长的萌芽期后进入高速发展期。根据艾瑞咨询报告，即使受到疫情的影响，2020年中国医疗美容市场仍然保持近20%的增长率，市场规模达到1975亿元。但是，在高速发展的过程中问题也随之产生，《中国医美“地下黑针”白皮书》显示，2020年，黑诊所数量已超60000家，是正规诊所的6倍。机构分散、服务水平不一、同质化竞争严重等问题成为行业发展的巨大阻力。在这种机会与挑战同在的背景下，行业迎来了并购潮，医疗美容行业相关企业及谋求转型医疗美容行业的企业陆续进场。截止到目前，国内国外对于医疗美容相关公司的并购案例研究极少，为了进一步研究医疗美容行业及相关企业的并购动因和并购为企业带来的影响，为相关并购操作提供实践参考，本文选取了具有一定代表性的上市公司A收购浙江省排名前三的医疗美容医院L的案例进行研究。2021年3月，A公司宣布完成对L公司的收购。本研究以此为例，运用文献研究法和案例分析法，深入探讨医疗美容服务行业中企业的并购动因及绩效，结合并购前后的相关指标表现，评析并购活动为A企业带来的影响。通过研究发现，一方面从并购动因的角度来看，医疗美容行业并购是基于行业发展的现状，部分企业转型与多元化选择的结果，其次也是医疗美容服务机构打破区域限制扩大市场份额、降低运营成本应对市场竞争以及实现上下游产业联动提高企业运作效率的主观需求。另一方面，从并购绩效的角度来看，从并购事件发生前后资本市场表现来看，综合市值、平均股价、超额收益来的数据可以看出，A公司对L公司的并购动作，获得资本的认可，股市表现积极。从并购前后的各项经营财务指标来看，并购让A公司的营运能力有所提高，并且在医疗美容服务板块的经营得到短时间的较快提升，但是对偿债能力却带了负向影响，因此，A公司长期发展仍需要在纵向和横向的拓展中寻找平衡，以追求可持续的发展。从非财务指标的表现来看，A公司在本次收购中达到了主营业务转变的目的，实现了经营管理上的协同效应。

The medical beauty industry in China originated in the plastic surgery departments of public hospitals in the 1980s. With the rapid expansion of the economy, the medical beauty industry has entered a period of rapid development after a long period of germination. According to the I Research report, even affected by the pandemic, the Chinese medical beauty market still maintained a growth rate of nearly 20% in 2020, with a market size reaching 197.5 billion yuan. However, problems have arisen during the rapid development process. The “White Paper on China’s Medical Beauty ‘Underground Black Needle’” shows that in 2020, the number of black clinics exceeded 60,000, which is six times the number of regular clinics. The dispersion of institutions, uneven service levels, and severe homogenization competition have become major obstacles to the development of the industry. In this context of both opportunities and challenges, the industry has ushered in a wave of mergers and acquisitions, and companies seeking to transform into the medical beauty industry and related companies in the medical beauty industry have successively entered the market. Up to now, there are very few studies on the merger and acquisition cases of medical beauty-related companies at home and abroad. In order to further study the motivation and performance of mergers and acquisitions in the medical beauty industry and related companies, this article selects the case of the representative listed company A acquiring the medical beauty hospital L ranked in the top three in Zhejiang Province for research.In March 2021, Company A announced the completion of its acquisition of Hospital L. Using literature research and case analysis methods, this study delves into the M&A motivations and performance of enterprises in the medical aesthetics service industry. By analyzing relevant indicators before and after the acquisition, we evaluate the impact of the M&A activity on Company A.Research has revealed that, on one hand, from the perspective of the motives behind mergers and acquisitions (M&A) in the medical aesthetics industry, such M&A activities stem from the current state of industry development and are partially the result of certain companies‘ transformations and diversification choices. Furthermore, these actions are driven by subjective needs of medical aesthetics service providers to break through regional limitations, expand market share, reduce operational costs to cope with market competition, and achieve upstream and downstream industry linkage to enhance operational efficiency. On the other hand, examining M&A performance, considering the capital market performance before and after M&A events, comprehensive data including market value, average stock price, and excess returns indicate that Company A‘s acquisition of Company L has gained recognition from the capital market, with positive stock market performance. Looking at various operational and financial indicators before and after the M&A, it is evident that the acquisition has improved Company A‘s operational capabilities and led to a rapid short-term enhancement in the operation of the medical aesthetics service sector. However, it has negatively impacted the debt-paying ability of Company A (excluding the potential impact of real estate divestiture). Therefore, for its future development, Company A still needs to seek a balance between vertical and horizontal expansion to pursue sustainable growth. Assessing non-financial indicators, Company A has achieved the purpose of transforming its main business in this acquisition, thereby realizing synergistic effects in operational management.
