摘　　要：文章利用我国2010-2021年开放式主动权益基金的季度面板数据,研究了投资者申赎行为所引起的基金被动调仓对风格漂移的影响,并探讨了基金季报披露质量的调节作用。研究发现,投资者申赎行为所引起的基金被动调仓是基金风格漂移的重要因素,被动调仓越严重,风格漂移程度越高。在考虑了模型的内生性以及替换重要变量后,研究结论依然成立。异质性分析发现,赎回型被动调仓对风格漂移的影响更大,基金被动调仓对风格漂移的影响也因基金经理个人特征不同而有所差异。进一步研究发现,风格漂移对基金未来业绩具有负面影响,但基金季报披露质量具有显著的调节作用,可以缓解基金被动调仓对风格漂移的不利影响,尤其是对赎回型被动调仓的调节作用更加有效。文章的研究反映了基金季报披露质量的重要性,为推动公募基金行业高质量发展提供了重要的政策启示。In recent years, public funds have become an important tool for residents to diversify investment. However, many funds show a phenomenon of style drift, which not only brings worse returns, but also hinders the healthy operation of fund market in the long run. Considering the forced trading of funds caused by investor behaviors and the immature information disclosure system of China’s public fund market, this paper deeply explores the relationship among funds’ forced trading, fund style drift and fund quarterly report disclosure quality to have a better understanding of fund style drift and investigate the significance of information disclosure quality.Using the quarterly panel data of China’s active equity funds from 2010 to 2021, this paper empirically analyzes the impact of funds’ forced trading caused by investor behaviors on style drift first, and then discusses the significance of fund quarterly report disclosure quality. It is found that funds’ forced trading resulting from investors’ purchasing or redeeming behavior is a considerable factor that triggers fund style drift. The greater the forced trading, the more serious the fund style drift. The conclusion is still valid after the robust test by considering the endogeneity of the model and replacing key variables. The heterogeneity analysis indicates that the impact of different types of forced trading on style shift varies, and redeemed forced trading exposes a greater impact on fund style drift than purchased forced trading. Besides, the impact of forced trading on fund style drift varies with fund managers’ individual characteristics. Further discussion finds that fund style drift has a significantly negative impact on future performances. What is more, fund quarterly report disclosure quality has an obvious moderating effect, and the improvement of disclosure quality can alleviate the impact of funds’ forced trading on style drift, especially redeemed forced trading.The contributions of this paper are as follows: First, it deeply inves
