摘　　要：基于2015—2020年A股上市公司数据,从公司权益资本成本的角度考察了中国监管问询机制带来的经济后果。研究结果表明,与未收到年报问询函的公司相比,收到年报问询函的公司在收函后面临更高的权益资本成本。在此基础上,采用中介效应检验证实了投资者信心是年报监管问询影响权益资本成本的一条有效路径。进一步分析发现,分析师不倾向于跟踪预测被出具问询函的企业,但收到重组类函件的企业在收函后权益资本成本反而更低。作为事后监管的一种重要手段,证券交易所问询函形式并未因其“非处罚性”而丧失效力,其不但有助于投资者及时调整投资决策,同时也有助于警示上市公司主动规范其信息披露行为。Based on the data of A-share listed companies from 2015 to 2020,this paper studies the economic consequences of China's regulatory inquiry mechanism from the perspective of equity capital cost.The results show that companies that receive annual report inquiries face higher equity capital cost than those that do not.On this basis,we use the mediating effect test to confirm that investor confidence is an effective path to affect theequity capital cost.Further analysis shows that analysts are not inclined to track and forecast the companies that have been issued inquiry letters;however,the equity capital cost of companies that have received restructuring letters is lower on the contrary.As a main means of postmortem supervision,the supervision in the form of inquiry letter of China's stock exchange will not lose its effectiveness because of its non-punitive nature.Regulatory inquiry can not only help investors adjust investment decisions in time,but also alert listed companies to actively regulate their information disclosure behavior.
