PPP模式是指政府和社会资本在基础设施及公共服务领域建立的一种长期合作关系,双方以特许经营权为基础,以合同来约定和明确各自的权利和义务,最终预期使合作各方达到比单独行动更为有利的结果。文章从财政风险视角下探讨了PPP模式在我国的发展历程,深入剖析了PPP模式下财政风险的成因。 相似文献

PPP模式下,公私双方控制权的合理配置与合作效率密切相关。针对PPP合作过程中公共部门和私人部门的能力差异性、目标差异性以及水利基础设施不确定性大的特点,结合不完全契约理论建立激励约束视角下水利PPP项目剩余控制权的优化配置模型;基于该模型,分析私人部门的投资额度、股权比例、技术水平、管理能力,以及公共部门的协调、监管、社会收益期望值等因素与剩余控制权配置比例的关系,进而提出一系列基于剩余控制权优化配置的激励约束方案。为PPP模式下公私双方的剩余控制权优化配置提供理论和应用依据,完善和补充PPP模式契约机制设计理论。 相似文献

研究发现,现有科技资源共享服务管理出现问题的根源在于未正确处理好科技资源"公共品"和"私人品"的双重价值属性矛盾。基于此,以重庆为例,充分考虑科技基础资源双重价值属性,结合国家鼓励社会资本参与科研基础设施社会化服务的政策要求,从PPP(公私合作)的视角,构建科技资源共享服务管理模式,建立保证该模式成功运行的成本收益分配机制、协调管理机制、资源整合机制、回报机制、激励与约束机制和相应制度。 相似文献

正一、PPP模式的相关理论(一)PPP模式的定义PPP(Public-Private-Partnership)即"公私合营",是基础设施和公共服务供给领域的重要创新,通过参与主体的多方合作,能够充分优化资源配置,实现"一个项目,多方赢利"的理念。PPP的定义具有狭义和广义之分。狭义的PPP是指政府引入私营部门组成的特殊项目机构(Special Purpose Vehicle, 相似文献

在国内外学者对政府和社会资本合作(PPP)模式对科技资源配置效率作用研究的基础上,通过分析我国科技资源产权中存在的问题,提出在科技资源配置中引入PPP模式,明晰科技资源产权,优化科技资源配置效率,促进科技创新。PPP模式在科技资源配置中通过"实置"科技资源产权主体、扩展产权客体、界定产权结构、整合科技资源收益权-控制权及剩余索取权-剩余控制权,实现科技资源组织形式上"量"与"质"统一、"公"控"私"管相结合,进而规范科技资源市场化行为,降低交易费用,加速科技资源共享,激发科技创新。 相似文献

With great care, Dr. ZHOU Zhonghe takes out a package wrapped by cotton tissue from a drawer and says: "This is the gem of our collections: the fossil of a bird that lived 125 million years ago!" Then, pointing at a tiny mound, he explains: "Look, this is the claw and that is the head. It was in the egg shell and ready to hatch ... The species fell into a family of waterside inhabitants." 相似文献

Prof. SUN Changpu from the CAS Institute of Theoretical Physics coworkers from University of Basel in Switzerland have worked out a way - at least in theory - to split a beam of molecules according to their chirality. The technique involves passing the molecules through three different laser beams is similar to the famous Stern-Gerlach effect whereby a beam of atoms passing through a magnetic field is split in two according to the atoms' spin states 《中国科学院院刊(英文版)》2008,22(1):23-23

<正>Between February and March of 2013,the source of avian-origin H7N9 human infection was discovered in Shanghai and Anhui,China.Prior to this,H7N9 has only exhibited characteristics of a low pathogenic avian infl uenza virus,carried by chickens with no known cross-species transmission.By the end of August 2013,Chinese mainland reported a total of 134 confi rmed cases of H7N9 human infections across12 provinces and 42 cities,resulting in 45 deaths.In October and November,Zhejiang Province found three new cases and Guangdong found one case of human infection,suggesting the possibility of a comeback in the fall and winter seasons.Researchers led by Prof.GAO Fu(George Fu Gao)at the Institute of Microbiology,CAS and Beijing Institutes of Life Science,have made progress on understanding 相似文献
