城市化、技术进步与城乡收入差距的动态分析 总被引:1,自引:0,他引:1
近年来中国城市化水平不断向前推进,技术进步程度日益提高,然而城乡收入差距却居高不下。为了深入分析这三者间的动态关系,基于向量自回归(VAR)模型,利用Granger因果检验和脉冲响应函数,对中国1985~2009年城市化、技术进步与城乡收入差距的关系进行动态分析。结果表明:城市化和技术进步是影响城乡收入差距的原因,对城乡收入差距的长期冲击效应均为正;城市化是推动技术进步发展的原因,反之,技术进步对城市化的影响效果并不显著。 相似文献

虚拟企业中组织间的知识共享有着自己的动力构成,在这个动力构成中,包含着三个动力要素:知识差的引发、利益的驱动和环境的激励。这三个动力要素分别存在于知识共享对象、知识共享主体和知识共享环境中,它们之间彼此联系,相互作用,形成了一个统一的动力机制,由此推动着虚拟企业组织间知识共享的运行。 相似文献

运用演化博弈论的方法,建立企业间合作演化博弈模型,研究知识更新对企业合作策略选择的影响。模型分析表明,企业均选择合作策略的概率与知识更新的收益系数及相互间的信任水平正相关,与知识更新的合作成本系数和风险系数负相关。在此基础上,提出了激励企业通过知识网络开展合作的策略建议。 相似文献

This paper contributes to the ongoing debate on the impact of academic patenting on publishing and knowledge transfer. Drawing upon two separate surveys of academics, and their CV information, we provide empirical evidence for UK academics in engineering and physical sciences. The contribution of this paper is two-fold. First, our findings show that (the intensity of) academic patenting complements publishing up to a certain level of patenting output, after which we find evidence of a substitution effect. We also find weak evidence of important differences across scientific fields with the more basic-oriented fields showing indications of a crowding-out effect. Second, our analysis of the potential impact of patenting on knowledge transfer shows a positive correlation between the stock of patents and engagement in knowledge transfer channels. However, we find that a substitution effect sets in, indicating an inverted U-shaped relationship between patenting and several knowledge transfer channels. 相似文献

The literatures on ‘varieties of capitalism’ (VoC) and ‘national innovation systems’ (NIS) propose very similar arguments about how firms require different types of labour qualifications to pursue strategies of radical product innovation (RPI), incremental product innovation (IPI), and product imitation (PI) respectively. Despite their similar lines of reasoning, however, the VoC scholars are concerned with the skill profiles of a firm's entire workforce, whereas the NIS proponents focus on the knowledge base of scientists. Given that both literatures have developed without explicitly taking the arguments of the neighbouring discipline into account, it is thus unclear whether they explain the same, or different, phenomena. Furthermore, both literatures propose firm level arguments but test them on the basis of macro- rather than micro-level indicators. This paper therefore asks: first, does micro-level evidence support the VoC and NIS arguments that particular types of employee skills and knowledge backgrounds of scientists are needed for different competitive strategies? And, if so, do RPI, IPI, and PI firms need to employ scientists in combination with a workforce having the respective qualifications, or is it sufficient if scientists or employees alone are adequately qualified. Quantitative analyses indicate that a particular mix of scientific knowledge combined with employee skills facilitate RPI, IPI, and PI strategies. The article thus concludes that - despite their similar reasoning - the VoC and the NIS literatures indeed describe different phenomena, without being aware of the synergies created whenever adequate employee and scientific qualifications are hired together. 相似文献

Indigenous knowledge erodes rapidly. When the loss of this knowledge negatively affects the lives and health of traditionally living rural communities, a drive to conserve indigenous knowledge becomes vital. This article argues that the transfer of indigenous knowledge on traditional vegetables will ensure the availability and utilisation of this important food source for resource-poor rural communities. Data collected on the present use of traditional vegetables at a rural Xhosa village in the Eastern Cape Province of South Africa documented indigenous practices of traditional vegetable use and measured attitudes and perceptions of young women. Findings revealed that although traditional vegetables are readily available, there is a decline in the use of traditional vegetables in this village. Since the loss of associated indigenous knowledge is a reality, and in view of the negative attitude towards traditional vegetables, future use of this valuable food source is threatened. The transfer of the associated indigenous knowledge holds the key to the potential future use of traditional vegetables. Altered perceptions of traditional vegetables are crucial for the conservation of the associated indigenous knowledge. As a result awareness campaigns to promote the use of traditional vegetables, related nutritional education, including proper cooking and preservation techniques are necessary. 相似文献

虚拟社区知识共享的动因分析——基于嵌入性理论的分析模型 总被引:1,自引:0,他引:1
以嵌入性理论为基础,构建了“认知-关系-文化嵌入性”的概念模型,从认知、关系和文化3个方面分析虚拟社区知识共享的动因,认为认知嵌入性、关系嵌入性和文化嵌入性有助于社区认同的建立,社区认同会促使个体分享自己的知识;关系嵌入性有助于信任的产生,信任会直接影响到个体的知识共享行为;文化嵌入性会直接影响到个体的知识共享行为;3种嵌入性之间相互作用,影响到虚拟社区中个体的知识分享行为。将嵌入性理论引入到虚拟社区知识共享的研究中,有助于更好地理解这种行为背后的动因.促进虚拟社区的发展和知识管理理论的深化。 相似文献
