本文研究的主要結論:第一,在我國風險資本來源中,政府風險資本一直居於主導地位,這造就了我國風險投資的「官辦官營」模式,使其契約機制從一開始就帶有「行政干預」的烙印;第二,有限合夥契約在約束機制、激勵機制、投資者收益三個方面都明顯優于公司制契約,因此是我國風險融資契約的發展方向,但由於有限合夥在我國受到法律限制,公司制契約在一定時期內仍是我國風險融資契約的主要形式;第三,融資契約報酬條款中的激勵系數受主體先驗概率影響,借鑒有限合夥契約,可對我國公司制融資契約進行改造與重構;第四,與債權契約、普通股契約相比,可轉換優先股契約可以有效緩解風險投資過程中的信息不對稱、降低代理成本,因此是我國風險投資契約的最優選擇。Powerful yet easy to use design optimizer, with support for multiple variables and constraints, finds optimum designs in minutes
