2014年中央明确要将新疆打造成“丝绸之路经济带核心区”,如何通过金融集聚赋能核心区建设,成为新疆亟需解决的问题。本文以新疆15个地州为例,从金融背景、金融规模、金融密度和金融深度四个方面共选取11项指标,构建其金融集聚能力评价指标体系,构造基于改进的熵值法综合评价模型,对2011—2017年新疆金融集聚能力的综合指数进行比较并进行时空演化分析。结果表明:(1)丝绸之路经济带核心区金融集聚能力总体发展水平呈明显提升趋势;(2)一定的经济规模是金融集聚的必要前提,乌鲁木齐的金融集聚能力优势突出,对周边地州的虹吸效应明显;(3)喀什地区和伊犁州直属县在15个地州中的综合表现较优,与乌鲁木齐形成“一主两翼”的金融要素集聚空间分布格局,与核心区城市定位、战略空间布局基本保持一致。建议通过建设中亚区域金融中心、培育产业集群、优化制度环境、完善基础设施等措施提升核心区金融集聚能力。

为了研究风荷载作用下输电塔-基础-地基耦合效应(SSI效应)对输电塔风致响应的影响,以一座特高压输电塔-基础-地基体系为例,按照离散刚度法设计其气弹模型,采用一个刚性质量块来模拟基础,U型弹簧和阻尼器来模拟地基,对气弹模型进行风洞试验,并研究地基阻尼和刚度对输电塔结构风致响应的影响规律。研究表明:1)考虑SSI效应后,模型的振动衰减要慢于刚性地基模型;同时,随着地基刚度的减小,模型的综合刚度减少且自振周期增大;2)地基刚度的减小会使上部结构位移和加速度响应逐渐增大,对塔脚反力基本没有影响;随着地基阻尼的增大,塔身加速度逐渐减小,但位移和塔脚反力几乎保持不变。因此,在进行输电塔结构设计时应考虑SSI效应的影响。

通过对变量之间施加短期和长期约束的SVAR模型分析房地产价格、股票价格波动与我国货币政策之间的关系。研究表明:我国货币政策对于房市的影响要高于股市;国内价格水平对资产价格波动的反应呈现非对称性,股市对价格水平影响要高于房市;资产价格的上涨会对实体经济产生正面影响,但是长期来说,这种拉动作用效果并不显著。最后,本文分析了实证结果的政策含义。
