This paper studies the problem of value-appropriation of supply chain, which is composed of a monopoly manufacturer downstream and multiple suppliers upstream. Firstly, we introduce two special examples in which output distribution of suppliers satisfy equal or equal-difference sequence. It is found that the more difference the distribution will be, the less preference will be gain by the manufacturer in the value-appropriation of supply chain. For the general distribution, the parameter ＂competitive residual＂ is introduced to score the influence of the suppliers＇ output quantity distribution on manufacturer＇s preference. The general conclusion will be given and it can directly deduce the conclusions above. Finally, we extend our basic conclusion to the more general situation in which the numbers of suppliers are not equal.

Heat shock protein 96 (gp96) is a highly conserved protein in the endoplasmic reticulum. The functions of gp96 include promoting the oncogenesis and progression of glioma. In addition, tumor-derived gp96 can activate anti-tumor immune. Therefore, this protein was used to generate an anti-tumor vaccine and widely applied to glioma therapy. This review summarizes the mechanisms of gp96 in glioma oncogenesis and clinical trials of the gp96 tumor vaccine in glioma treatment.

"主辅分离"是深化国有企业改革的需要,但大部分企业还处在"分而不离"的状态。如何让这些衍生企业独立发展、自主创新并获得良好绩效成为该政策的关键。衍生企业组织演化过程被划分为两个维度,即价值创造驱动和独立性约束。本文深入考察了一个国有企业的衍生企业发展历程,深度跟踪和提取了其七年的事件数据,通过纵向研究和扎根理论试图来填补理论缺口。通过实地调查、访谈与档案的抽取和印证数据,分类绘出事件的时间线索趋势图;通过纵向动态的相互趋势的不断比较,得到价值创造驱动和独立性约束分别与外部关系探索、亲缘关联关系和自主性投入一致性关系。研究主要的理论贡献在于把创业衍生企业的理论延伸到"主辅分离"这一具体政策导向措施的作用机理中,并得到其理论模型与核心权衡过程。

作为引导地方产业发展的重要载体,地方平台企业需要利用其政策优势汇聚相关市场主体共同开发地方特色资源。地方平台企业既需要采取价值获取行为有效“分配蛋糕”,也需要实施价值创造行为“做大蛋糕”。由于自身不具备产业能力,平台企业极易出现单一价值行为过度发展,造成产业过度膨胀或资源恶性竞争的不利局面。通过对一家地方平台企业的事件路径分析,本文从功能相互依赖视角探索了其如何通过价值创造与价值获取互动来应对价值行为失衡的过程规律。研究结果表明:(1)地方平台企业需要打破紧密的功能相互依赖结构激活价值创造,稀释过度发展价值获取行为;(2)可以固化开放的功能相互依赖结构承接价值获取,整合过度发展的价值创造行为;(3)注重紧密性与开放性结构的规律迭代,融合稀释与整合过程,构建承载价值创造与价值获取持续冲突的贯穿构型。本研究对价值行为失衡应对以及功能相互依赖做出理论贡献,也对引导特色产业发展具有启发意义。
