三峡工程移民安置规划创新性总结

针对三峡工程淹没范围广、项目多,移民数量大,时间跨度长,库区环境容量不足,经济社会重构与移民搬迁等多种矛盾交织,水库移民技术标准及理论亟待创新等诸多难题,在三峡移民安置规划中,通过大量深入细致的调查研究,建立了完整的水库淹没处理及移民安置规划技术体系;引入环境容量概念,建立了移民安置环境容量评价理论及分析方法;提出“投资包干、限额规划”,妥善处理了补偿与发展的关系;借鉴资产评估理论,提出受淹工矿企业补偿投资核算的新方法;制定了三峡水库库底清理和水库移民工程验收工作技术标准,以创新的成果指导了三峡移民实践。为三峡移民实践提供了强有力的技术支持。     

复杂排沙廊道泄流能力分析研究

排沙廊道是水电站设计中常见的一种建筑物,在工程设计中对于一些形态弯曲、结构及流态复杂的排沙廊道,目前能有效测算其泄流能力的计算公式并不多见。以南盘江大桥水电站为例,基于水电站首部枢纽水力学模型试验资料成果,以能量方程为基础,从单位流量所产生的阻力损失进行分析,建立了本工程复杂廊道泄流能力计算公式,计算成果同模型试验成果相吻合,可供类似工程设计参考,也为类似复杂建筑物泄流能力分析提供了研究思路。

我国基金选股选时能力实证分析

本文运用西方基金绩效评价中较为常见的选股选时能力模型及其FF3改进模型对我国证券投资基金进行实证研究,在处理过程中考虑了不同取样频率和不同样本区间的影响.研究结果表明:(1)我国基金只存在很小程度的选股能力,而基本不存在选时能力,更没有基金同时具有选时能力和选股能力;(2)多因素改进模型与原模型相比显著提高了解释能力,说明在可能的情况下应尽可能使用多因素模型;(3)加快取样频率后基金表现出更强一些的选股能力,但在各年度内基金的选股能力有所差异.     

Benefiting from network position: firm capabilities,structural holes,and performance

While strategy scholars primarily focus on internal firm capabilities and network scholars typically examine network structure, we posit that firms with superior network structures may be better able to exploit their internal capabilities and thus enhance their performance. We examine how innovative capabilities—both those of focal firms and those they access through their networks—influence the performance of Canadian mutual fund companies. We find that a firm's innovative capabilities and its network structure both enhance firm performance, while the innovativeness of its contacts does not do so directly. Innovative firms that also bridge structural holes get a further performance boost, suggesting that firms need to develop network‐enabled capabilities—capabilities accruing to innovative firms that bridge structural holes.

Cross‐Border Auction Cycle Effects of Sovereign Bond Issuance in the Euro Area

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.     

中蒙俄经济走廊建设中内蒙古与蒙、俄产能一体化分析——以钢铁、水泥为例

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。     

Unpacking systemic innovation capacity as strategic ambidexterity: How projects dynamically configure capabilities for agricultural innovation

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.
