摘　　要：信息披露是注册制改革的核心,科创板首次公开披露IPO审核问询与回复,是对核准制下信息披露制度的重大改革。科创板IPO审核问询能否发挥预期的信息挖掘和价值发现功能,帮助投资者评估新股价值,提升IPO定价效率?文章研究表明,科创板IPO审核问询回复函的信息特征显著影响了机构投资者询价意见分歧,具体表现为:回复函叙述性披露内容越多、可视化信息量越大、文本可读性越高,机构投资者询价意见分歧越低。公司研发投入越多,回复函信息特征对询价意见分歧的影响越大。此外,当交易所明确指出回复函存在信息质量问题或者首轮问询后仍多次被问及核心科技问题时,回复函信息特征对询价意见分歧的影响显著减弱。在控制了机构投资者"抱团压价"等非理性因素的影响后,结论依然稳健。文章基于科创板IPO信息披露的分析,从定价效率视角提供了评价科创板注册制改革的经验证据,也为监管方进一步提高审核问询质量,提升IPO定价效率提供了参考。The STAR market is expected to play a great role in the realization of “breaking through the core technologies and helping China to enter the forefront of innovative countries” proposed by the Fifth Plenary Session of the 19th Central Committee. The STAR market reforms the previous requirements of the profitability and corporate governance for companies going public. In the STAR market, multiple sets of listing standards are adopted and IPO candidates can choose an appropriate one to apply an IPO. The STAR market offers IPO opportunity to unprofitable companies, red chip companies and companies with special voting rights. Meanwhile, the complicated listing standards of IPO and candidates with high technology or nonstandard corporate governance bring much higher information asymmetry between IPO candidates and investors. To reduce this information asymmetry and increase IPO pricing efficiency are critical to the success of the new STAR market and the reform of IPO registration system. The IPO comment letter system is the most important measure to reduce this information asymmetry. The Shanghai Stock Exchange will issue comment letters to IPO candidates and require them to give explanations or supply more materials.Taking listed companies from July 22, 2019 to December 31, 2020 in the STAR market as samples, we study the impact of information quantity and quality of response letters from IPO candidates on the divergence of institutional investors’ bids. We find that the more the words, the greater the amount of visualized information or the higher the readability of the text of response letters, the lower the divergence of institutional investors’ bids. The impact of the above information quantity and quality of response letters on the divergence of institutional investors’ bids is much higher in subsamples with higher R&D investment than in subsamples with lower R&D investment. Further tests show that when the information quality of response letters is lower or when the candidates are still challenged ab
