| The STAR(Science and Technology Innovation Board)Market was launched on June 13,2019.On August 23,China Securities Regulatory Commission officially issued the "Special Regulations on Major Asset Restructuring of Companies Listed on the STAR".Compared with M&A(Mergers and Acquisitions)in other sectors,M&A on the STAR Market place more emphasis on industrial synergy and audit efficiency,while also strengthen information disclosure and intermediary responsibilities.In order to encourage M&A on the STAR Market,the regulations have lowered company’s major asset restructuring criteria,reduced the price of issued shares,and increased payment methods.In general,these regulations are conducive to the marketization and standardization of M&A on the STAR Market.As more high-tech companies choose to list on the STAR Market,the M&A are bound to become more frequent.Since the STAR Market has only been launched for three years and relative M&A regulations have just been released,there is little literature on M&A research.Therefore,studying the existing cases of M&A on the STAR Market will have important implications for the future M&A on STAR Market.Individual investors in China are mostly small and medium investors,they prefer to allocate their limited attention to short,prominent and attractive information.At the same time,because lack of professional financial knowledge and the uneven ability to obtain information,they are prone to overconfidence and herd behavior in stock trading,and their emotional tendencies are susceptible to external influences.Therefore,based on related researches in psychology and behavioral finance,this thesis traces the changes in the attention and emotional tendencies of small and medium investors during M&A,and analyzes the consequences of M&A from the perspective of investor reactions.Due to the rapid development of Internet,online forums have increasingly become an important platform for investors to obtain information,and are also
