【摘要】 本文基于有为政府增信治理的研究视角，运用股权溢价理论，以生成股权溢价风险对冲的损失方式，提出有为政府与有效市场交互作用的公共治理模式。通过引入PPP板块典型个股案例分析发现，PPP投融资运营稳健性，源自于“有为政府+有效市场+有益企业”的有效治理。同时，有为政府增信治理与有效市场议价激励，调控资本市场议价凸显股权溢价，使SPV组织的上市公司成为有益企业。实证分析认为:通过中国PPP政府增信治理的适度管制与政策组合作用，政府增信治理对于市场议价作用是显著的;同时，PPP板块上市公司规避风险损失行为比增加风险收益行为更加谨慎——即凸显了禀赋效应。这为风险投资者规避风险收益风险对冲的损失提供了决策支持，也有助于为有为政府增信的有效治理找到政策调整与策略行为的协同参考点。更多还原
