近年来中国经济呈现出一定的“脱实向虚”趋势,对企业的风险管控与持续发展提出了严峻挑战。以2003—2019年中国A股中央企业控股公司和非国有公司为样本,本文考察了国有资本管理改革对企业金融资产投资的影响。研究发现:(1)中央企业利润上缴政策实施显著抑制了企业的金融资产投资行为,且主要表现为对投机性金融资产的抑制;(2)随着上缴比例的不断调高,政策效果愈发明显;(3)当企业资源丰富、行业盈利能力较弱以及高管业绩偏好较高时,政策效果受到一定削弱;(4)政策实施降低了金融资产中的“投机”成分,进而缓解了企业经营风险。本文从宏观政策角度丰富了企业金融化影响因素的研究,也丰富了国有资本管理改革政策经济后果的研究。本文的结论对于完善国有资本管理制度、深化国有企业改革具有较为重要的政策意义。
