我国铅锌企业低碳生产水平的“DS-BP”评价模型及其实证检验 总被引:1,自引:0,他引:1
文章建立了低碳经济背景下的铅锌企业低碳生产水平评价指标体系,并同时结合BP网络和DS证据理论的优点与最新研究成果,提出了我国铅锌企业低碳生产水平的DS-BP评价模型。实证检验表明:该模型具有很好的有效性和普适性,能有效避免和改善现有其他评价方法难以面对的信息残缺、信息模糊和信息容错等问题,从而从一个崭新的角度较好地解决了铅锌企业低碳生产水平评价问题,为铅锌企业低碳战略的制定及实施提供了一种有用的分析工具和决策支持。 相似文献

An option contract pricing model of relief material supply chain 总被引:1,自引:0,他引:1
Relief material management which aims to reduce the impact of disaster and maintain social stability is of great importance for nonprofit organization (NPO) such as government, department of civil affair or Red Cross. However, the research of efficiency and performance on this field has long been ignored. In order to improve the efficiency and performance of the relief material management, we apply the supply chain management method into this field. Considering the relief material management system as a supply chain with one buyer and one supplier, we introduce the option contract mechanism into relief material supply chain management. With reasonable assumptions, we design an option contract with two delivery steps, and build an option pricing model with binominal lattice to estimate the different values of the same option contract for both members of supply chain. Furthermore, we analyze the impacts of the different parameters (such as the ratio of inventory, subjective probability of disaster, etc.), on the supply chain and its members in detail. The numerical example presented at last demonstrates that, with two delivery steps, there is a feasible price range of option contract which makes both members of relief material supply chain profitable and willing to conduct the transaction with option contract. 相似文献

以我国制造企业为研究对象,从供应商网络视角出发,探索了战略采购对制造企业知识获取的影响。构建了包括战略采购、供应商网络嵌入性、制造企业与供应商互动、制造企业知识获取之间关系的概念模型并提出了相应的理论假设。采用结构方程模型进行验证,实证结果表明战略采购对关系嵌入性、结构嵌入性和制造企业与供应商互动均有显著的正向影响,并进而通过它们显著正向影响制造企业知识获取。 相似文献

员工沉默是近年来组织行为学研究关注的新问题之一,本研究采取问卷调查的方法,选择某移动通信集团公司的40个团队、314对员工-上司配对作为研究对象,探究了领导授权行为、信任对员工沉默的影响作用,结果表明,领导的授权行为中展示关心对于员工沉默具有直接的负向预测作用;对管理者高度信任的员工能感受到更多的领导授权行为,且更少保持沉默;员工对管理者的信任会调节在信息共享、展示关心和员工沉默(自评)之间的关系,当员工对管理者具有高度信任的情况下,上司表现出的信息共享和展示关心会使得员工沉默程度明显降低;反之,当员工对管理者缺乏信任的情况下,上司表现出的信息共享和展示关心会对员工沉默没有影响甚至会使员工更加保持沉默。 相似文献

“后来者劣势”与我国企业发展新兴技术的对策 总被引:13,自引:1,他引:12
我国发展新兴技术的道路充满了曲折,有必要提出"后来者劣势"的概念来进一步探讨和认识有关发展中国家发展新兴技术的理论与我国实践之间的巨大反差.研究表明,"后来者劣势"的核心不是技术问题,而是市场问题.即使我国企业在新兴技术开发上取得了突破,同跨国公司相比,也更不容易被市场接受.这一结论表明,需要重新思考企业、政府、以及用户和消费者在我国发展新兴技术中的作用和对策. 相似文献
