基于差异产品的政府最优R&D补贴策略研究 总被引:1,自引:0,他引:1
本文建立考虑产品差异的三阶段双寡头博弈模型:第一阶段政府选择R&D(Research and Development)补贴率,第二阶段企业确定自己的R8LD水平,第三阶段企业确定产品价格进行伯川德竞争.根据双寡头在第二和第三阶段是否合作,给出了R&D竞争、R&D卡特尔、共同实验、技术共享联盟和研究共同体等五种R&D策略,得到了相应的政府最优R&D补贴率.研究表明,当技术溢出程度较低且产品水平差异不大时,政府给予采用R&D竞争策略企业的补贴率不高于采用R&D卡特尔策略的企业;当技术溢出程度较高且产品水平差异较大时,结果则相反.在政府进行最优补贴后,从促进技术进步、扩大企业规模以及社会福利最大化的角度来看,五种R&D策略中,共同实验最差,技术共享联盟和研究共同体则最优. 相似文献

After presenting a historical overview of the concept of work and the different meanings that it has acquired over the centuries, the author analyses the value it holds for Europeans, and the impact on work and employment of the popular rhetoric about a technological revolution and its “inevitable” consequences. She then considers the future of work in the light of three scenarios: a “dismantling of labour law”, a “technological revolution” (where automation brings an end to employment), and an “environmental transition”. She argues that the latter is compatible with the imperative to take action on climate change and the expectations placed in work and employment. 相似文献

Les territoires traditionnels de chasse et de trappe des Cris dans les régions méridionales du bassin de Moose River ont été infiltrés au début du XXe siècle, par les colons euro-canadiens et l'exploitation des ressources qui s'est ensuivie, avec l'encouragement actif du gouvernement provincial. Après la Deuxième Guerre mondiale, ces tendances se sont également propagées au nord du bassin. Selon de nombreux contemporains, l'économie basée sur la chasse et la trappe des Cris s'était désintégrée face à la concurrence des Euro-Canadiens et l'appât du travail rémunéré et de la vie villageoise. Cependant, de récentes études sur le terrain démontrent l'importance continue et la viabilité de l'économie autochtone traditionnelle du bassin de Moose River.
The traditional hunting and trapping territories of the Cree in the southern reaches of the Moose River Basin were infiltrated by Euro-Canadian settlement and resource-based development early in the 20th century, with the active encouragement of the provincial government. After the Second World War, these trends were also evident in the northern part of the Basin. Many contemporaries believed that the Cree hunting and trapping economy had disintegrated in the face of Euro-Canadian competition and the lure of wage labour and village life. However, recent field studies document the continuing importance and viability of the traditional aboriginal economy of the Moose River Basin. 相似文献

Over the past decade, the level of clinical needs of youth in residential treatment has increased significantly. Youth in out-of-home settings typically experience higher levels of psychotropic medication use than their peers living at home, even when controlling for the severity of clinical issues. The purpose of the current study was to examine the effects of an approach to clinically reassess psychotropic medication utilization for youth residing in residential treatment settings while also observing the impact on the youth's need for physical containment. Medication changes were based on a data-informed process, using input from a multi-disciplinary treatment team. Data for 531 youth who were consecutively admitted to one of two non-affiliated intensive residential treatment programs, one in the Midwest and one in New England, was analyzed. Over half of these youth (n = 292, 55%) had their medications reduced during their stay and only 14% (n = 76) were prescribed more medication at discharge than they had been taking at admission. The remainder either saw no change during their stay (n = 104, 20%) or were never on medication at any time (n = 59, 11%). From admission to discharge there was a 62% decrease in the number of assaultive incidents as well as a 72% decrease in the use of physical restraints. These results support the view that residential treatment can provide a treatment milieu that allows for thoughtful reassessment of the clinical basis for behavioral disorders in children that can achieve the dual goals of medication reduction and behavioral stabilization. 相似文献

以旧换再补贴政策已经在我国试点施行,相关原型新品和再制品的市场购买行为和企业定价决策受此影响。根据传统销售和售后渠道以及消费者持有旧件质量的不同细分市场,考虑到消费者的"以旧换再"偏好程度构建了制造商分级定价利润模型并分段优化,得到了"以旧换再"补贴下的最优分级定价决策,面向企业给出了旧件分级再制造的成本条件,面向政府给出了授予企业产品补贴资格的参考依据。考虑到再制造领先企业和一般企业再制造条件的不同,采用算例分析展示了补贴对领先企业及一般企业再制造分级定价决策的影响,并分析了消费者"以旧换再"偏好程度的变化对企业分级再制造决策的影响。结果表明,分级定价可以提高再制造系统的整体利润;换购补贴对促进再制造领先企业与一般企业再制造体系发展的积极作用不同,政府应根据产业及企业特点结合其他举措选择实施补贴的时机和补贴比例。 相似文献

Teaching and learning in the neoliberal academy means that educators in non-market-oriented departments, such as social work, face several constraints and challenges when trying to implement an anti-oppressive, social justice focused curriculum. This article considers challenges that can arise with an introductory social work course in the current context of neoliberalism, especially when open to both social work and non-social work students. With a particular focus on larger class sizes, the use of precarious labour and the depoliticization of the classroom, the authors use an inductive, reflective approach to analyse observations made about shifts in the behaviour and engagement of students in the course. The authors surmise possible explanations for these shifts, considering changes made to the substantive content and pedagogical practices of the course. Through this process the authors propose that these changes represent an ‘activist pedagogy’ which may offer potential for anti-oppressive education with students both inside and outside social work. As such, the authors propose ‘activist pedagogy’ as a possible way to resist and subvert the neoliberal educational paradigm and to better integrate the principles and practices of social justice and anti-oppressive social work into the classroom. 相似文献
