从分析供需匹配之间存在的冲突入手,提出一种基于图模型冲突分析法来求解供需匹配问题的思路。首先在图模型视角下给出供需匹配问题的研究框架,分析不同类型的供需匹配问题,设定决策主体和决策策略;然后讨论不同匹配类型下的状态约简、偏好表达,进行稳定性分析;最后通过应用案例,将图模型法与群决策匹配算法进行对比分析,验证图模型求解供需匹配问题的有效性。 相似文献

外资研发嵌入激发区域自主创新活力的同时也会引发冲突问题。本文将政府补贴作为外资研发与自主创新主体冲突及结盟问题的调节机制，应用GMCRII即冲突分析图模型理论，构建冲突图模型并求解冲突均衡解，探索外资研发中心与自主创新主体冲突稳定性结局及结盟特征。结论指出，在政府补贴调节作用下，外资研发采取依托母公司先进技术并吸收本地前沿技术的双重策略实施网络嵌入，而自主创新主体则倾向构建内部结盟以应对外资研发策略调整。基于政府补贴视角的冲突均衡分析为政府部门关于外资在华研发的科技决策提供了理论借鉴。 相似文献

政府投资项目决策权配置构造实证研究 总被引：5，自引：0，他引：5
本文研究政府投资项目的决策权配置构造与项目绩效之间的关系.实证研究表明,政府投资项目决策权配置具有独特的构造,对决策主体行为和项目的绩效产生重要影响.决策权与知识和责任不匹配,是导致政府投资项目效益低下的关键因素.应改革政府投资的非正式制度,并用项目管理的市场代理模式取代行政代理模式. 相似文献

随着社会主义市场经济体制的不断完善,随着投资体制改革的不断深化,政府不再是唯一的投资主体,企业在投资中占据的地位也在不断扩大。经济评价是工程建设项目投资风险分析的基本依据,是项目决策合理化科学化的重要手段。由此可见经济评价对工程建设投资项目的重要性,本文分析了工程建设投资项目的经济评价。 相似文献

CAS should stick to the principle of rendering service to, and giving impetus for, the development of China＇s science enterprise by making S＆T innovations, said CAS President LU Yongxiang. The CAS president made the remarks in a recent talk to communicate the gist of the winter session of the Party＇s Leading-member Group at CAS, which was held from 7 to 11 January in Beijing. 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
