This paper explores the industrial affiliation and linkages of research and technology organizations (RTOs) in nine North Italian regions highly specialized in advanced manufacturing and introduces a methodology to assess the potential for a cross-regional technology platform. RTOs are supposed to operate in the development and application phases of innovation and are expected to provide access to key enabling technologies and R&D infrastructures. An original survey panel of 55 Italian RTOs is used and Social network analysis is introduced to assess the potential of RTOs to operate as a single cross-regional platform across key industrial and technology domains. Centrality measures are used to build an empirical model on the factors that drive the higher centrality of RTOs. Centrality is increased by convergence on few key technology priorities and is positively correlated with collaborative ventures, the number of contracts with firms and the presence of distinctive R&D infrastructures. Such a platform rests on specialized regional hubs, it operates with no gatekeepers and it only partially exploits geographical and technological proximity within the network. Future research avenues are discussed to improve the function of technology diffusion of RTOs in a cross-regional perspective.  相似文献

多类型微博舆情时空分布关系的差异性及其地理规则   总被引:1,自引:0,他引:1  
以新浪微博转发行为作为舆情时空分布的研究对象,分别选取4·20雅安地震事件代表重大社会舆情、凤凰古城收费事件代表公众生活舆情、郭某某事件代表网络热点舆情3类案例,总结不同类型微博舆情的时空分布特征及差异性,进而透视客观存在的地理规则。研究发现:①3类舆情事件微博转发量的时间分布分别表现为:长尾型、山峰型、多个时间段上的波浪型。②与时间轴对应的空间分布呈等级结构,信息扩散节点城市等级(转发量)结构还会表现出一定的空间伸缩变形或与距离衰减形成叠加关系,3类事件分别表现为:延续传统规律的“始终金字塔”结构、在相对较长时间过程中具有范围伸缩的“始终金字塔”结构、距离衰减影响下的“始终金字塔”结构。城市规模效应主导和距离摩擦阻尼效应影响构成网络信息空间分布的基本地理规则。③微博舆情时空分布的差异性与事件类型有关,并与不同微博用户的作用有关。微博用户的不平衡区域分布和其跨区域流动对信息空间分布产生直接影响。  相似文献

传统手工业作为农区经济发展的一种重要形式,对广大农区经济发展具有重大推动作用。本文以兰考县徐场村为例,刻画了传统手工业在欠发达农区产生与发展的历程,探究其影响因素的作用机理。研究发现:①传统手工业的形成与发展是沿着初创、波动、恢复和发展等四个阶段展开,中后期的产业规模扩大较为显著;②家庭作坊呈现“小集聚,大分散”的分布格局,务工人员的来源分布较为集中但存在“灯下黑”现象,市场体系逐渐健全;③传统手工业主要受到个体因素、村庄内部和外部因素三个层面因素的影响,且在产业发展的不同时期主要影响因素并不相同;④从演化视角来看,偶然事件与收益递增的结合往往锁定了传统产业新的发展路径,而集聚效应与衍生活动的互补增强则进一步促进了传统手工业产业集群的形成。  相似文献

The objective of this article is to explore the theoretical foundations of a wicked game. The theoretical part is based on the notion of wicked problems, which is developed further. It is also illustrated that the latest innovation strategy of the European Union, called smart specialization, resembles a wicked game. Comparison between the two revealed several similarities gives new insights into the theory of wicked problems and into the process of smart specialization.  相似文献

Drawing on previous studies related to the evolutionary aspects of regional innovation systems (RIS), this paper examines how an exogenous shock reduced organizational thinness, fragmentation and lock-in and thereby facilitated path creation and RIS emergence in a peripheral region. A longitudinal case study approach, based on primary data from 39 interviews conducted between 2008 and 2012, is used to investigate how a region was affected by the sudden entry and subsequent activity of a multinational oil company. A multi-level analysis illustrates how this exogenous shock facilitated change at the firm, public authority and macro (regional) levels and thus provides a holistic understanding of the complex mechanisms that underlie regional transformation. The analysis illustrates how the entry of the oil company reduced organizational thinness by stimulating the establishment of external firms. The existing regional actors then managed to reduce their organizational lock-in by adapting their skills and resource bases to new knowledge provided through interfirm relationships (reduced fragmentation), and this reduced organizational lock-in and fragmentation ultimately strengthened the industrial structure and further contributed to regional path creation. A number of innovations were observed, and in combination with the “thickened” institutional structure, this represented the means for an emerging RIS.  相似文献

Despite the importance of the Clovis–Folsom transition for understanding the history of western North America, its spatiotemporal dynamics remains unclear. Here we report a three-part study in which we investigated the transition using radiocarbon dates from Clovis and Folsom sites. In the first part of the study, we used dates from Folsom site-phases to determine when and where Folsom originated. In the second part of the study, we employed Clovis and Folsom dates in analyses designed to determine whether Folsom spread via demic diffusion or cultural diffusion. In the third part of the study we investigated the velocity of the Clovis–Folsom transition. The analyses suggest that Folsom first appeared around 12,800 calBP in the northern High Plains and spread north and south from there. They also suggest that the spread of Folsom was, at least in part, the result of population expansion. In addition, the analyses indicate that the spread of Folsom was relatively fast for a prehistoric diffusion but well below the maximum velocity that has been estimated for such events. These findings, in turn, have implications for the hypotheses that have been put forward to explain the Clovis–Folsom transition. They refute the idea that the Clovis–Folsom transition resulted from an extraterrestrial impact over northern North America at 12,900 ± 100 calBP but are consistent with the alternative proposal that the transition was a response to climate-driven environmental change.  相似文献

思维创新是领导活动发展和变革的先导,实践是领导思维创新的源泉。实践活动没有止境,思维创新也没有止境。领导思维的创新过程,是发现规律、认识规律、掌握规律的过程;领导思维的创新,必须反映社会实践发展的客观要求,并且要由实践来检验修正。那些经不起实践检验的、不能为人民群众谋利益的创新,都不能称为是真正的创新。  相似文献

We gauge the relative impact of economics, demographics, and politics on the decisions of 79 rural North Carolina counties whether to site a prison in the period 1970–2000. The results of this model demonstrate that, contrary to the expectation that counties site prisons in response to economic distress, the demographic characteristics of each county affect the relative likelihood of a prison siting more than its economics does. The influential demographic predictors are those inextricably bound up with development options—the education levels of its citizens—and those that limit its ability to pursue controversial projects—its not-in-my-backyard (NIMBY) constituencies—rather than those that measure its racial diversity. Therefore, prison siting is neither a simple story of economic determinism nor one of environmental racism. We use a proportional hazards regression to model this innovation adoption in response to the challenge to select methods that take the potential time dependence of adoptions into account. A duration model is also particularly suitable for cases such as this one for which the innovation adoption is better understood as a process than as an event.  相似文献
