摘　　要：本文在科创板背景下,研究战略投资者对IPO抑价的影响。研究发现,公司引入战略投资者的配售比例与IPO抑价率显著正相关,表明战略投资者在参与科创板IPO过程中存在认证效应。进一步研究发现,该认证效应在引入更多战略投资者和研发强度更高的公司中更为明显。此外,公司引入战略投资者的配售比例还与公司IPO抑价率的后续效应,即上市后的未来市场表现显著正相关,说明战略投资者的认证效应不仅引发上市初期的较高抑价,还会推高新股上市后的价格。本文研究结论为探讨我国注册制市场IPO抑价问题提供了新的视角,也为我国监管机构优化战略配售机制、促进科技创新企业发展提供了经验证据。In 2019,China set up the Science and Technology Innovation Board(STAR Market)and the pilot registration system to improve the basic construction of the capital market and promote the development of high-tech and strategic emerging industries.The STAR Market has introduced a strategic placement mechanism to support listed firms in introducing strategic investors.Before the establishment of the STAR Market,the strategic placement mechanism had no“useful place”in the A-share market due to the immature conditions of China's A-share market and the scarcity of new share resources.Therefore,the early studies on strategic(cornerstone)investors and IPO underpricing were all based on Hong Kong H-shares,and the conclusions varied considerably.More needs to be understood about whether strategic investors will affect IPO underpricing in emerging markets.Based on the institutional background of the STAR Market,this paper examines the impact of strategic investors on IPO underpricing rate from the perspectives of the information asymmetry theory(rational investors)and the investor sentiment theory(bounded rational investors)respectively.Using data from the STAR Market,we find that the placement proportion of the firms introducing strategic investors is significantly positively associated with the IPO underpricing rate.Finding a positive relation implies that the certification effect of strategic investors will increase IPO underpricing.Considering that the quantitative characteristic of investors and the R&D intensity of issuers will affect the certification role of strategic investors in IPO issuance,we further examine the impact of the above factors on the relationship between them.It is found that the above certification effect is more pronounced for firms with a larger number of strategic investors and a higher level of R&D intensity.In addition,we also find a significant positive association between the placement ratio of strategic investors and the subsequent effect of IPO underpricing rate(the future market performan
