Asymmetric effect of financial stress on China’s precious metals market: Evidence from a quantile-on-quantile regression

Constructing the China’s financial stress index (CFSI), this paper investigates the asymmetric impact of financial stress on precious metals by employing a novel quantile-on-quantile approach. The results show that precious metals can be used as a safe haven to hedge financial market risks. However, the risk aversion of precious metals varies under different precious metals market conditions. In addition, the structural changes in the effect on precious metals are found after the global financial crisis, reflecting the heterogeneity of the relationship between financial stress and precious metals before and after the global financial crisis. These results have meaningful implications for investors and risk managers.     

现代产业集群：金融危机下有色金属产业发展的路径选择

与传统产业集群的低端发展路径不同,现代产业集群是以创新为基础、走产业高端发展路线的具有创新型的产业集群。它能提高产业整体竞争力、降低交易成本、促进企业工艺技术创新和软实力创新。当前我国有色金属产业处于一种初级形态的块状经济状态,没有形成现代产业集群。金融危机导致我国有色金属产业出现了需求锐减和行业巨亏等巨大冲击,究其根本在于其没有形成现代产业集群,培育有色金属现代产业集群是该产业发展的必由之路,为此应重塑政府在集群形成中的作用、延伸有色金属产业链、促进产业结构升级及构建技术创新体系。

提高我国大宗商品价格话语权的金融对策研究--从有色金属的角度

进入21世纪以来,随着我国经济持续高速发展,城镇化和工业化推动了我国对大宗商品的消费,产量也相应地快速增长,与此形成鲜明对比的是,由于价格话语权的缺失,我国政府和企业始终未能摆脱大宗商品价格受制于人的尴尬局面。本文以有色金属为例深入分析我国大宗商品价格话语权缺失的现状及其原因,认为现阶段金融化因素在国际大宗商品的形成过程中的作用日益凸显。在此基础上,有针对性地提出提高我国大宗商品价格话语权的金融对策和措施。

The Coevolution of Relationship Dominant Logic and Supply Risk Mitigation Strategies

How and why do risk mitigation strategies evolve? And which resources are needed for engaging in such changes? This paper contributes to the understanding of risk management in supply chains by developing theory about the interplay between supply risk mitigation strategies and the purchasing team's relationship dominant logic (RDL), which we define as the purchasing team's orientation toward and shared cognitive map of the management of its supply chain relationships. Specifically, we propose that RDL and supply risk mitigation strategies are fundamentally intertwined. Following a Straussian approach to grounded theory, this study analyzes data generated from the purchasing teams of Western green‐tech firms trying to mitigate supply risk for technically indispensable rare earth metals from China. Our findings from this context that is heavily shaped by state‐influenced supply chain members show that the firms chose their mitigation strategies in line with their RDL. Human capital, social capital, and financial capital seem to moderate the link between RDL and mitigation strategies. We link our findings with the strategic management literature in deriving theoretical propositions concerning these relationships.
