借助新中国成立以来的历史数据,分析70年间中国经济高速增长的主要动能及其转换过程。通过数理推导,首先扩展出含有人力资本分布的经济增长模型,然后对各个历史时期的增长动能进行分解,发现实物资本对经济增长始终具有重要的促进作用,人力资本则在20世纪90年代后开始显著促进经济增长,逐渐成为保持中国经济持续增长的新动能。人力资本分布对经济增长的影响以人力资本积累产生显著作用为前提,分布的平衡化有利于人力资本的积累和溢出效应,进而间接促进经济增长,但促进中国经济增长的人力资本结构不是按照受教育程度“阶梯型”分布,而是“剪刀型”分布。因此,应当将人力资本作为经济增长新旧动能转换的着力点,进一步优化教育资源投入,改善人力资本结构,使人力资本积累及其结构更好地耦合产业结构调整和升级,更有效地赋能经济增长。 相似文献

In the hard sciences research programmes are designed to generate evidence consistent or inconsistent with particular hypotheses. Hypotheses unsupported by evidence are modified or abandoned. The framers and testers of scientific hypotheses are members of the same profession, similarly trained and likely to interpret evidence in similar ways. They have professionally generalized responsibility for the quality and integrity of each other's work. Peer review systems are in place to monitor performance and expose chicanery. This is not the case in the cultural policy research arena. Here, policymakers, arts advocates and academic policy analysts are breeds apart. Their professional affiliations and lines of accountability are radically unlike. We have highly selective “advocacy” evidence on the one hand; highly developed but untestable academic theory on the other, suggesting the hypothetical existence of evidence for which academics are not allowed to look. Policymakers avoid “what if?” questions because they are paid to maintain positions of certainty. Academics ask, but lack the data to answer. Neither approach is satisfactory for shaping the future. This paper explains how the two opposing research traditions came into being and points to some of the problems which poor communication between theoreticians and practitioners can create. 相似文献

虚拟社会是数字化的现实社会中的人在互联网建构的虚拟空间内依据特定的规则进行生产和生活活动的人化场域。社会分层作为虚拟社会的重要现象存在和发展,由作为虚拟社会纽带的信息的特性、虚拟社会物质基础的技术特质决定,是现实社会权力向虚拟社会延伸的结果。虚拟社会分层可以从虚拟社会接入情况、虚拟社会政策供应、虚拟社会工具供应、虚拟社会信息供应、虚拟社会信息意识、虚拟社会信息获取、虚拟社会信息利用和虚拟社会信息伦理等八个维度进行考察。 ICT 技术革新带来虚拟社会阶层的分化与流动以及虚拟社会阶层间聚合互动现象不断增长是虚拟社会分层发展趋势。 相似文献

Interactions between public research organizations and industry can be conceptualized as having three main stages: drivers of interaction, channels of interaction, and the perceived benefits from collaboration. Both of the agents differ in terms of the incentives they have to collaborate and the behaviors they adopt during the collaboration process. Following a three-stage model based on Crépon et al. (1998), this paper discusses the impact of drivers of collaboration on channels of interaction, and the impact of these channels on the perceived benefits by researchers and firms. The methodology also allows firm-level benefits from interaction to be connected with researchers’ characteristics via the analysis of four common channels of interaction for firms and researchers. The study is based on original data collected through two surveys, carried out in Mexico during 2008, of R&D and product-development managers of firms and of academic researchers. Our results show that all channels of interaction play an important role in determining benefits; however, they differ in terms of their impact on short- or long-term benefits for firms. The channels related to joint and contract R&D, property rights, and human resources are the best, as they have a higher impact on long-term benefits for firms. Policy implications derived from this study focus on specific actions that enhance those researchers’ characteristics related to the best channels for fostering long-term benefits for firms. 相似文献

The proliferation of cell phones and the growing culture of constant connectivity has introduced a plethora of new challenges for mobile citizens. One of the major challenges transportation professionals desire to address involves the use of cell phones to text while driving, especially for less experienced drivers. In this study, the Theory of Planned Behavior (TPB) in conjunction with psycho-social factors is utilized to explore the intention to text while driving among young drivers. The results of a survey administered to 524 drivers suggest that the TPB constructs (attitude, subjective norm, and perceived behavioral control) along with the perceived disadvantages of abstention and age of the driver explain a significant amount of variance in the intention to send text messages while driving (adjusted R2 = 0.71). 相似文献

假定企业是一个彼此异质的知识的集合体和积累知识的有效制度,而知识传导是“知识接收者”与“知识提供者”间的互动学习。在此前提假设下从后发企业知识接收者的视角研究知识流动规律及其转移路径,提出知识传导的主体边界、知识传导活动、知识属性三个维度所构建的整合传导路径框架,剖析单维度和两两维度组合的子路径过程,然后,分析知识传导路径的广度、密度、速度和交互性等关键特征及其影响知识传导的机理,最后,以深圳研祥公司为例,印证本研究的相关结论。 相似文献

依据地理位置和医疗水平与设施把我国医院分为两个战略群组:中心医院和基层医院。基于这一战略群组划分,分析了我国医院间合作的市场动因和政府动因。结论认为,在医疗体系改革的影响下,中心医院合作的市场动因是通过合作扩大他们的影响,获取更多"病源",发挥规模经济优势;基层医院合作的市场动因是通过合作获取知识来提高自身的能力。另外政府为了改善医疗服务,也在促进基层医院与中心医院之间的合作,形成了我国医院间合作的政府动因。 相似文献

“双环扣”培训模式拟在培训内容上衔接和扣紧两个不同的知识领域,即培训的目的一方面要提高校车驾驶员的职业技能和职业道德素质,另一方面要使校车驾驶员掌握基本的青少年儿童心理学知识,并运用正确的教育方法引导学生心理品质的健康发展。“双环扣”培训模式具有一定的理论基础、要素构成和运行机制,并需要其他的措施加以保障。 相似文献
