构建旅游景气指数体系及预警机制的探讨--以杭州市为例

伴随着国民经济的发展,我国国内旅游发展迅速,被称为“国民经济提升的催化剂”。然而受到旅游业市场规模、国内外政治经济环境、生态环境以及一些不可抗力(如新冠疫情)等多方面影响,旅游行业很有必要建立一套景气指标体系,从而预测旅游业的经济走向,提供预警功能,以保证旅游业平稳有序发展。     

企业安全风险分析与管控措施研究

随着各行各业的现代化发展,国家对行业生产安全提出了越来越高的标准,无论是哪个行业,在开展生产作业的过程中,都要注重安全风险的分析和管理。安全风险可能会存在于生产经营的各个阶段,且种类繁多。为促进安全生产标准化目标的实现,企业在日常的工作中,应将安全管理与经济效益实现置于同等重要的地位,不断就各种的安全风险,来制定有针对性的安全处理方案和应急预案。     

论我国商业银行金融风险预警指标体系

Entry in the presence of dueling options

This paper investigates the influence of industry uncertainty on the decision by established firms to enter a new industry. Specifically, we examine the tension between the option to defer , which discourages entry in the presence of uncertainty, and the option to grow , which may encourage entry in the presence of uncertainty when there are early mover advantages. Empirical analysis on data from a broad array of industries revealed that the effect of uncertainty on entry is not monotonic. Our findings are the first to find support for the nonmonotonic effect of uncertainty that has only recently emerged in theoretical treatments of real options theory, and amplify the importance of considering both the option to defer and the option to grow when contemplating entry. Furthermore, we found evidence that the relationship between uncertainty and entry is moderated by: (a) irreversibility, which influences the value of the option to defer; (b) the total value of growth opportunities; and (c) early mover advantages, which magnify the value of growth options.

Systemic event prediction by an aggregate early warning system: An application to the Czech Republic

This work develops an early warning framework for assessing systemic risks and predicting systemic events over a short horizon of six quarters and a long horizon of 12 quarters on a panel of 14 countries, both advanced and developing. First, we build a financial stress index to identify the starting dates of systemic financial crises for each country in the panel. Second, early warning indicators for the assessment and prediction of systemic risk are selected in a two-step approach; we find relevant prediction horizons for each indicator by a univariate logit model followed by the application of Bayesian model averaging to identify the most useful indicators. Finally, we observe the performance of the constructed EWS over both horizons on the Czech data and find that the model over the long horizon outperforms the EWS over the short horizon. For both horizons, out-of-sample probability estimates do not deviate substantially from their in-sample estimates, indicating a good out-of-sample performance for the Czech Republic.     

不确定环境下的地震应急救援路径优化研究

针对地震应急救援的特点,引入不确定理论,在地震灾害的背景下,研究震后动态网络环境下的应急救援路径选择问题。用不确定变量表示网络中各路段的破坏程度,综合考虑路径破坏程度及车辆路径连续性等约束条件,以救援时间最短为目标,基于不确定理论建立了动态优化模型,并用改进的遗传算法求解,最后设计算例验证了模型和算法的有效性。
