面对百年未有之大变局，提高韧性是企业应对危机、逆势成长所需的关键能力。文章基于2012—2022年我国沪深A股上市公司数据，分析机构投资者实地调研对企业韧性的影响及作用机制。研究表明：机构投资者实地调研能够显著提升企业韧性，这一作用可通过信息效应即缓解企业融资约束和治理效应即增加企业创新投入来实现；媒体关注度和企业的国有属性在机构投资者实地调研促进企业韧性提升的过程中均发挥了负向调节作用；异质性分析发现，基金类投资机构开展实地调研对企业韧性提升的促进作用最大，对处于成长期和衰退期的企业开展实地调研可促进企业韧性提升，对处于成熟期的企业开展实地调研反而会削弱企业韧性。今后应推动形成常态化实地调研工作机制，加强企业与投资者的信息沟通与共享，以持续提升企业韧性。

Facing the unprecedented changes in a century, enhancing resilience is a key capability that enterprises need to cope with crises and grow against the odds. Based on the data of A-share listed companies in Shanghai and Shenzhen from 2012 to 2022, this article analyzes the impact and mechanism of institutional investors' on-site research on enterprise resilience. The research shows that on-site research by institutional investors can significantly enhance enterprise resilience, which can be achieved through the information effect, that is, alleviating the financing constraints of enterprises, and the governance effect, that is, increasing the innovation investment of enterprises. Media attention and the state-owned nature of enterprises both play a negative moderating role in the process of institutional investors' on-site research promoting the enhancement of enterprise resilience. Heterogeneity analysis reveals that the promotion effect of on-site research by fund-type investment institutions on the enhancement of enterprise resilience is the greatest. On-site research for enterprises in the growth and decline stages can promote the enhancement of enterprise resilience, while on-site research for enterprises in the mature stage may weaken enterprise resilience. In the future, a regular on-site research working mechanism should be promoted to strengthen information communication and sharing between enterprises and investors, so as to continuously enhance enterprise resilience.
