摘　　要：IPO定价问题长期困扰我国资本市场。在注册制落地之际,上海证券交易所在科创板引入跟投制度试图解决这一问题。本文利用科创板IPO公司的数据检验跟投制度对IPO定价的影响效果及其作用边界。研究发现,承销商跟投比例越高,IPO发行价越低,表明跟投制度可以抑制承销商抬高发行价的机会主义行为。上述抑制作用在治理水平较高的发行公司中相对较弱。进一步研究表明,当公司股价增长潜力较大时,跟投制度对发行价的抑制作用在一定程度上被弱化。此外,跟投制度能抑制超募资金规模,但为.了补偿跟投带来的风险,发行公司倾向于提高上市公司的承销费率。最后,跟投制度有助于提升IPO后的市场绩效。本文的研究结论为促进中国资本市场注册制的发展与完善提供了理论依据。The issue of IPO pricing has plagued China’s securities market for about three decades.For the sake of protecting investors, the securities regulatory authorities have exercised administrative control over the IPO price for a long time, but this has led to pricing inefficiency and distortion of firm value.From 2000 to 2002 and from 2009 to 2012,China Securities Regulatory Commission(CSRC) pushed forward the market-oriented reform twice.However, after the relaxation of pricing control, the phenomenon of "three-highs" appeared, with the wealth distribution skewed to the issuer and the loss of investors.In June 2019,the Shanghai Stock Exchange launched the STAR Board and piloted the registration system, which means that the "hand of the market" will gradually dominate the review and issuance of new shares in China’s IPO market.The STAR Board piloted the underwriter co-investment system in the IPO market for the first time, which requires the underwriters to subscribe in proportion for the public offering shares of the company to be listed at the offering price and lock them in for 24 months after the listing.The co-investment ratio is determined by the size of the offering.The purpose of introducing this system in China is to restrict underwriters’ behavior through capital and strengthen their awareness of performing their duties and responsibilities, so as to protect investors’ interests.Whether the co-investment system can effectively curb underwriters’ opportunistic behavior in China’s IPO market deserves our attention and exploration.Under the traditional IPO system, the underwriter is a sponsor, and its income only comes from underwriting.However, under the co-investment system, the underwriter also acts as an investor.If the underwriters raise the IPO price, their investment costs will rise, thus reducing their returns and even leading to losses from co-investing.Thus, theoretically, underwriters must carefully consider the consequences in order to ensure the expected returns on the co-investment.T
