国企改革全面深化，市值提升有迹可循。新一轮国改以提高核心竞争力为主，一利五率、市值管理等考核体系渐趋完善。我们认为，国有独资企业的利润上缴、国有股权的分红、股权增值转让等，是国有资本经营预算收入的重要来源，有望弥补土地财政收入下滑的影响。国有资产价值创造弹性大，2022 年全国国有资产总额/国有资产权益分别达到 340/95 万亿元，且 2023 年国有企业总收入/利润总额达 86/4.6 万亿元，呈现资产体量大，但 ROE、周转率低的特点，我们认为经营改善、股权价值提升带来的利润创造弹性较大。此外，从绝对估值层面看，一利五率均可对应到 DCF 模型当中，意味着随着考核的深化推进，国有股权价值理论上具备价值回升的基础。
