Toon Meelen 《Technology Analysis & Strategic Management》2013,25(8):957-970
An integrated framework for the analysis of sustainable innovation policy was developed, based on a combination of the transition management (TM) framework, the strategic niche management approach, and policy recommendations, resulting from technological innovation system (TIS) studies. In the framework, the multi-level view from TM has been integrated with the functions approach from the TIS literature. The integrated policy framework shows that specific policy goals and measures can be found at the specific points of intervention related to (the interfaces between) landscape, regime, TIS and niches. The integrated framework suggests that stimulation of a TIS only makes sense when this action is well aligned with landscape and regime developments. The framework should be used in empirical studies for further testing and refinement. 相似文献

Consistent with the challenges of sustainability science, land architecture offers a comprehensive approach to land system dynamics useful for numerous types of assessments, ranging from the vulnerability of coupled human–environment systems to forest transitions. With antecedents in several research communities, land architecture addresses the tradeoffs within and between the human and environmental subsystems of land systems in terms of the kind, magnitude, and pattern of land uses and covers. This approach is especially cogent for changes in tropical forests, given the broad-ranging forces acting on them and the equally broad-ranging consequences of their loss. The rudiments of the land architecture approach are illustrated for changes in seasonal tropical forests in the southern Yucatán of Mexico, the pivot of which is the Calakmul biosphere reserve. Simplifying the dynamics involved, the region-wide land architecture is the collective design of stakeholders with different land-use goals that favor tradeoffs in subsystem outcomes serving better either the reserve and related programs or the smallholder farmers that populate the region. A major tradeoff involves forest cover per se, which holds implications for forest transition theory. Evidence for an incipient transition involves the scale of analysis taken. The dynamics involved hold too much uncertainty to forecast a permanent transition to more forest cover and imply that more complex but robust versions of the theory are required. 相似文献

长尾理论表明,互联网更利于利基市场的发展。然而,近期有研究认为热门市场在网上更有优势。为了验证在线商家在这两类市场的不同表现,我们对淘宝网上的791家店铺的64万余种产品的销售数据进行了分析。结果表明,网上销售受到信誉、产品多样性、价格、口碑以及被推荐机会等因素的影响,并且这些影响在利基和热门市场上表现出显著的差异。其中,信誉、产品多样性、价格和口碑对利基产品销售的影响更大。基于历史数据的被推荐机会对热门产品的销售有正向影响,而对利基产品的销售有负向影响。此外,我们还发现了网上销售的后发优势。 相似文献

Alongside neo-classical supply-side analysis, there was the emergence in the 1980s of a new strand of anlysis seeking to develop a social-institutional perspective on the supply-side of modern industrial economies. This paper contrasts the views of labor market ‘flexibility’ provided by neo-classical analysts and supporters of deregulation with those of the Flexible Specialization and Diversified Quality Production theorists and assesses the strengths and weaknesses of Flexible Specialization in comparison to its main ‘institutionalist’ rival. It concludes that the anlysis of ‘supply-side institutionalism’ and the evidence provided by important empirically based studies, suggests that public policy directed towards: optimizing job training, promoting employee participation and inter-firm co-operation, and restricting the ability of firms to indulge in short-termism will be most productive in promoting the cause of socially progressive industrial production and ‘goodwork’. 相似文献

Mark Jablonowski 《Journal of Risk Research》2013,16(10):1221-1229
As optimism is becoming ever more apparent, progress carries with it both promise and pitfalls. Though it is quite natural for humans to take an optimistic view of life, this optimism must at the same time be tempered with realism. We cannot therefore let a focus on average, or expected, outcomes cause us to ignore possible high-stakes (existential) risks associated with what is becoming an increasingly complex world. In this paper, we argue that a more complete view is necessary for a proper assessment of not only the technical aspects of high-stakes risk management, but also the social, political, and economic framework within which it is carried out. Unfortunately, attention to such crucial details is not often the case. 相似文献
