We provide evidence for the euro area of spillovers from foreign public debt auctions into domestic secondary‐market auction cycles. We also confirm existing evidence of such spillovers from domestic issues into the domestic secondary market. Consistent with a theory of primary dealers’ limited risk‐bearing capacity, we find that auction cycles from domestic issues are stronger during the recent crisis period, whereas cross‐border effects are stronger in the precrisis period, but this evidence is not strong. This finding likely reflects the opposing effects of reduced sovereign bond market integration during the crisis and higher yield covariances caused by more market volatility. 相似文献

在“一带一路”倡议背景下,内蒙古凭借地缘优势、人文优势正在积极参与中蒙俄经济走廊的建设,并发挥着重要作用。内蒙古通过对蒙、俄输出钢铁和水泥,对促进内蒙古的经济增长起到了一定的积极作用。本文利用TVP-VAR模型实证检验证实,内蒙古对蒙、俄在钢铁、水泥的产能输出,短期内对第二产业的增长影响较为显著,但中期影响减弱,长期影响不明显。因此,内蒙古应抓住机会,通过产能一体化进一步化解钢铁、水泥过剩产能,从而实现产业结构升级和创新发展。 相似文献

The paper analyses the optimal pricing of the product quality scheme when concerns for relative standing exist among consumers. We demonstrate that if the proportion of high‐value consumers is over (respectively, under) 1/2 of the total consumers, a firm has an incentive to select a large (respectively, small) quality gap among products. Therefore, there exists a cut‐off level for status concerns, which eliminates quality differences, and the firm assigns the same quality to all the consumers. These results indicate that consumers’ qualities will reflect distortions at the top and bottom. Accordingly, the firm's profit depends on which consumer category is larger. 相似文献

Problems in agriculture and land use are increasingly recognised as complex, uncertain, operating at multiple levels (field to global value chains) and involving social, economic, institutional, and technological change. This has implications for how projects navigate complexity to achieve impact. However, few studies have systematically evaluated how project actors engage with other actors to configure capabilities and resources across multiple levels in agricultural innovation systems (AIS), from the individual to the network, to mobilise and build systemic innovation capacity. An analytical framework conceptualising the nested configuration of capabilities at multiple levels in the AIS is applied to two projects that successfully tackled agricultural and land management problems of differing complexity: (i) improving lamb survival; and (ii) sustainable land management in New Zealand. Findings indicate that innovation capacity constitutes project actors interacting with other AIS actors to configure capabilities and resources at different levels of the AIS in order to leverage positive project path dependencies and break path dependencies that are created by existing and historical capability configurations. Project actors also balance exploiting existing innovation capabilities, as well as using adaptive capability for exploring and creating new capability configurations to respond to emerging circumstances. This implies that projects should have strategic ambidexterity in terms of how they combine exploiting existing and exploring new networks to access, combine, create, or disconnect certain capabilities to address ‘capability voids’ in AIS. This requires support to projects to constantly scrutinise, through reflexive monitoring by dedicated facilitators, specific agriculture and land use policies connected to major sustainable development models (e.g. climate smart agriculture, urban farming, smart farming). The can help assess whether the AIS provides the right mix of capabilities and whether this is adequately supported by innovation policy, to realize transformative policy objectives. 相似文献

在知识经济的背景下,吸收能力被认为是企业提升绩效和增强创新的战略能力.社会网络被认为可以对潜在的吸收能力和实现的吸收能力都产生积极影响.本文从社会网络的关系层面,从外部和内部两个视角,分别阐述了社会网络如何影响吸收能力的两个维度.本文还从提升吸能力的视角,提出了有效构建和维护社会网络的措施. 相似文献

Recreation carrying capacity (RCC) is one of the most important indictors used in measuring the usage limits for the forest park resources. However, the consensus has not been reached with respect to the RCC’s content and its measuring metrics. In this paper, we attempt to establish a new RCC theoretical framework based on the demand theory of the tourism product characteristics. In the process, the choice experiment and orthogonal design methods are used in questionnaire designs and the conditional Logit model is used for parameter estimates. More than 700 park visitors are surveyed for data collection at the Shenyang National Forest park of Liaoning province in China. The primary park attributes being considered encompass vegetation, coverage, water quality, number of rubbish on the park trail path, admission fees, and congestion. The carrying capacity threshold for each specific attribute is identified. 相似文献

[目的]粮食生产能力关系到粮食供给和国家粮食安全,如何提高粮食生产能力是我国亟待解决的问题。文章以宾县为例,通过一定的方法探索粮食生产能力的影响机制,最终提出提高粮食生产能力的合理建议。[方法]利用农户调查数据,借助Logistic模型探讨自然因素和社会经济因素对粮食生产能力的影响特点。[结果](1)品种技术推广、作物收益对粮食生产能力的影响效应在1%水平上达到显著;(2)生育期变化、土地质量、旱灾、耕作方式对粮食生产能力的影响效应在5%水平上达到显著;(3)温度、降水、冷害及农业生产资料投入对粮食生产能力的影响效应在10%水平上达到显著;(4)温度与降水是否集中在生育期内、出售情况、农业引导政策对粮食生产能力的影响不显著。[结论]针对研究结果,该文提出,可从预防低温冷害、健全水利设施、完善耕地保护制度及加强农业基础设施建设等方面提高粮食生产能力。 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
