近年来,越来越多的非金融企业将大量的资金投资于金融资产,使得我国经济出现了明显的“脱实向虚”趋势。文章基于同群效应的视角,考察了我国企业金融化行为传染效应的存在性、发生机制及其经济后果。利用2007−2016年间沪深A股上市公司的数据,文章研究发现,企业的金融化决策存在显著的传染效应,企业的金融化程度与同行业或同省份其他企业的平均金融化程度显著正相关,该结论在控制内生性问题后仍然成立。“信息学习”动机和“代理成本”是驱动企业金融化同群效应的潜在原因,主要表现为具有信息劣势的追随企业倾向于模仿具有信息优势的领导企业的金融化行为,但反之不成立;并且,外部信息环境越差、不确定性程度越高、代理成本越高,企业金融化的同群效应越强。进一步研究发现,基于同群效应的金融化降低了企业的特质风险,但增加了企业面临的系统性风险和总体风险。文章的研究为理解我国经济“脱实向虚”的发生机制及经济后果提供了一个新的微观视角。
