产品市场与金融市场作为信息集散和企业监控机制在功能上具有一定的替代性;同时,当事人在两个市场上的战略行动又会产生溢出效应,从而形成两个市场间的战略互补关系。两市场间的这种相互作用客观上弱化了各自的协调失灵问题。进一步引入不确定性,发现当事人知识的差异性也会导致专业分工,从而刺激具有不同专业知识的人采取有溢出效应的战略行动,结果导致了两市场之间的战略互补关系。这种不确定性引发的两市场战略互补对经济增长有重要影响,并且其中也有乘数效应。 相似文献

权威格局是各种权威要素因地位差异构成的功能互补的社会秩序协调机制,对权威格局的研究是从合法性角度对社会政治稳定必须具备的民众基础的考量。调查结果显示:新疆社会政治稳定具备牢固的维吾尔族民众基础。维吾尔族民众信任的权威格局中。以领导干部为代表的法理型权威在个人和社会事务两个领域普遍受到信任,占据权威格局的主导地位,辅之以在社会事务方面越来越受到信任的知识能力型人才代表的新型权威。经济愈发达的地区,情况愈是如此。宗教人士所代表的传统权威能够发挥的作用主要局限在社会事务领域中的道德规范,在经济欠发达地区的作用相对更大。 相似文献

Homogenization of agricultural landscapes affects ecological processes and biodiversity and can affect the community composition of ecosystem service providers. These effects can have particular impact in landscapes dominated by monocultures of pollinator-dependent tree crop plantations, which create both spatial and temporal homogeneity at the landscape scale. I looked for associations between the proportion of nearby unmanaged vegetation and potential wild pollinator groups collected within flowering almond orchards in two types of landscape. In the Complex landscape, characterized by a heterogeneous mosaic of multiple crops, semi-natural grassland and natural woodland, insect pollinator groups were not associated with unmanaged vegetation. In the Simple landscape, dominated by monoculture almond plantations, most pollinator groups showed positive relationships with the two unmanaged vegetation types (grassland and woodland). In particular, all wild bee and all but one hoverfly individual were found in remnant native vegetation patches within almond plantations, rather than within rows of almond trees. More research is necessary to identify how structural differences created in monoculture landscapes, between crops and the native vegetation they encroach on, influence ecological communities and the provision of ecosystem services. 相似文献

城市宏观级差地租是我国特殊国情下的创新理论。先梳理了城市宏观级差地租理论的发展和最新成果,在前人研究的基础上,提出一些新的理论观点。之后对城市宏观级差地租的概念进行了新的诠释,然后重点论述了城市宏观级差地租的形成机制,并结合我国实际情况,分别从城市区位级差地租、城市规模级差地租和城市功能级差地租三方面进行深入分析和论述,阐明了城市宏观级差地租形成的原因。最后总结了我国城市宏观级差地租理论创新的意义,指出中央政府对宏观级差地租理论的运用是缩小我国区域经济差距一个新的政策思路。 相似文献

The use–make framework is employed to explain functional forms in production theory, including Cobb–Douglas and Leontief. Productivity and efficiency are interrelated by augmenting the framework with a linear program that determines the frontier output. 相似文献

The paper is concerned with testing normality in samples of curves and error curves estimated from functional regression models. We propose a general paradigm based on the application of multivariate normality tests to vectors of functional principal components scores. We examine finite sample performance of a number of such tests and select the best performing tests. We apply them to several extensively used functional data sets and determine which can be treated as normal, possibly after a suitable transformation. We also offer practical guidance on software implementations of all tests we study and develop large sample justification for tests based on sample skewness and kurtosis of functional principal component scores. 相似文献

This paper investigates the reasons why some technologies, defying general expectations and the established models of technological change, may not disappear from the market after having been displaced from their once-dominant status. Our point of departure is that the established models of technological change are not suitable to explain this as they predominantly focus on technological dominance, giving attention to the technologies that display highest performance levels and gain greatest market share. And yet, technological landscapes are rife with technological designs that do not fulfil these conditions. Using the LP record as an empirical case, we propose that the central mechanism at play in the continuing market presence of once-dominant technologies is the recasting of their technological features from the functional-utilitarian to the aesthetic realm, with an additional element concerning communal interaction among users. The findings that emerge from our quantitative textual analysis of over 200,000 posts on a prominent online LP-related discussion forum (between 2002 and 2010) also suggest that the post-dominance technology adopters and users appear to share many key characteristics with the earliest adopters of new technologies, rather than with late-stage adopters which precede them. 相似文献

The financial system is currently undergoing a revolution brought about by e-finance, digital convergence, new market entrants and government-encouraged competition. New market entrants such as Apple, Alibaba, Facebook and Google come from industries such as IT, retail, social media and telecoms, and, therefore, do not fit comfortably within traditional financial institutional structures. A functional perspective might provide more practical insights into this revolution; however, the functional perspective has had a limited impact. This paper will investigate the benefits and limitations of financial functional analysis; probe the underpinning principles of sociology’s structural functional analysis; revisit Merton and Bodie’s (1995) six core financial functions in relation to new entrants in the financial landscape; and, finally, argue that in the new financial environment, functional analysis provides a more coherent and explanatory framework of the financial system for students and practitioners alike. 相似文献
