摘要： 近年来，证券交易所推行的问询函监管逐渐成为保障和改善上市公司信息披露质量的重要机制，其实施效果自然成为监管者和学者关注的焦点。本文从银行的角度研究问询函监管对外部利益相关者的溢出效应，具体考察问询函监管对银行信贷决策的影响。研究发现，在公司被出具问询函后，银行的贷款利率显著更高，贷款期限显著更短，银行贷款要求提供担保的可能性和比例更高。进一步研究发现，当公司处于信息风险和信用风险相对较高的情境中，或银行对信息风险和信用风险较为关注的情况下，银行贷款利率上升幅度更加显著，不过，贷款期限、担保要求等非价格条款并没有显著差异。同时，问询函对银行信贷决策的影响在银企之间存在较强的信息不对称时更加显著。最后，本文发现公司收到问询函以后，分析师预测分歧度显著提高，这表明信息风险是问询函监管影响银行信贷决策的一个可能渠道。
