新冠肺炎疫情将对中国产业供应链的持续竞争力形成挑战,使企业面临人力短缺、成本增加、现金流紧张和供应链不确定性增高等问题,在企业供应链的原材料供应、采购管理、生产复工、物流以及市场等方面均会产生一定的负面影响,这对供应链弹性管理提出了新的要求。在政府层面,应建立综合、协同性的产业供应链风险管理和沟通机制,构建基于事件的产业供应链预警体系,保障企业供应链运营的资源体系,推动产业平台和产业集群带动供应链参与者建立供应链弹性体系。在企业层面,应建立基于企业事件的供应链预警体系,根据供应链预警信息和状况,合理规划供应链运营方式,运用数字化能力建设企业供应链弹性体系,稳定供应链运营,提升供应链效率。  相似文献

Despite the proactive efforts of many firms to combat gender bias within their organizations, societal prejudices still disadvantage women leaders and the firms who employ them. This external gender bias shapes outside stakeholder evaluations of women leaders’ efforts in various ways, and firms need strategies to cope with this external gender bias. We examine the conditions that might alleviate this burden of external bias and what women leaders and top executives can do to leverage these conditions—from a strategic positioning perspective—that will effectively allow female leaders to differentiate their work. To do this, we synthesize and build upon evidence that the external gender bias against women leaders diminishes when they lead in areas that are unconventional rather than mainstream. We then propose a two-step process based on (1) identifying the likely threat of external gender bias, which is stronger in some industry contexts than others, and (2) leveraging unconventionality to circumvent male prototypical comparisons, thereby reducing the hazards of external gender bias.  相似文献

We study the cost of shocks, that is, jump risk, with respect to reserve management when the reserve process is formulated as a drift‐switching jump diffusion with a reflecting barrier at 0. Inspired by the Brownian drift switching model, our model results in a more realistic dynamic behavior of international reserves than the buffer stock model. The new model can capture both the jump behavior in reserve dynamics and the leptokurtic feature of the increment distribution which has a higher peak and two asymmetric heavier tails than the normal distribution. Through the selection of an initial distribution that reflects certain steady state behaviors, the reserve process becomes a regenerative process. This selection enables us to derive a closed‐form expression for the total expected discounted cost of managing reserves, thus helping us to numerically find management strategies that minimize costs. The numerical results show that shocks at the reserve level have a significant effect on reserve management strategies and that model misspecification can result in nonnegligible additional costs.  相似文献

A conceptual truth about risks is that they involve a possible and future adverse effect or a negative value of some kind. The genetic risks that individuals may face in the health care setting differ in some crucial respects to other kind of risks. The aims of this paper are to analyse the notion of value in the context of genetic risk in the setting of health care, and to suggest a conception of the evaluative aspect of genetic risk that is fruitful for genetic risk information. Two influential and relevant approaches to value, preferentialism and the capability approach, are discussed in the light of certain distinctive features of genetic risk and a third, a sensibility theory of value is suggested. According to this view, the concept of risk is a so-called ‘thick’ evaluative concept that has both a world-guiding function as well as an action-guiding or normative function. It is argued that this provides a more promising way to think about genetic risks in the clinical setting.  相似文献

Export strategic orientation research suggests that export entrepreneurial orientation (EO) and market orientation (MO) directly affect export performance. Based on the dynamic capability theory, this study hypothesizes that export resource transformation capability is an intervening factor that helps explain how EO and MO, individually and jointly, impact export performance. Using archival and survey data from small and medium‐sized exporters in the United Kingdom and Nigeria, the study finds that export resource transformation capability partially mediates the individual effects of EO and MO on export performance in both samples. Results further show that export resource transformation capability does not mediate the joint effect of EO and MO on export performance. The findings help provide a more complete understanding of how export strategic orientations might be related to export performance. © 2016 Wiley Periodicals, Inc.  相似文献

产业集聚和市场集中是影响区域创新能力的重要因素。本文考察了京津冀、长三角两大经济圈制造业产业集聚与市场集中对区域技术创新能力的作用。实证分析结果表明:两大经济圈制造业集聚与市场集中均在一定程度上促进了区域创新能力的提升,但由于两大区域体制机制条件、创新环境、产业组织形态等不同,制造业产业集聚影响区域技术创新的程度、特征与路径也存在一定差别。两大经济圈应采取差异化集群发展方式,加快推进制造业集群升级,特别是应抢抓第四次工业革命发展机遇,提升制造业智能化水平,提升区域创新能力水平。  相似文献

[目的]通过测算各地区农业科技资源的配置能力,分析其比较优势并找出不足以便弥补差距,促进各区域农业科技配置能力的提高,为各地区农业经济的发展提供支持。省级农业科学院作为各省市规模最大、综合实力最强的农业科研机构,是农业科技创新的重要主体之一,分析其科技资源配置能力具有重要的现实意义。[方法]基于2009—2016年相关数据,遴选了有代表性的评价指标体系,运用突变级数法计算农业科技资源配置能力,运用NRCA模型定量分析农业科技资源配置效益的比较优势。[结果]山东农业科学院科技资源配置能力位居全国第一,甘肃、江苏、青海农业科学院分别在农业科技人力、物力、财力资源方面具有明显的比较优势。[结论]省级农业科学院科技资源配置能力区域差异十分明显,但区域格局变化不大,且大致与各地区经济实力相吻合;农业科技资源配置能力较高的农业科学院大多在农业科技物力资源配置效益方面具有比较优势,在农业科技人力、财力资源配置效益方面不具备比较优势。  相似文献

文章基于物流业增加值、服务业增加值等西部省市的平衡面板数据,对中国西部区域物流业发展现状与区域经济的关系进行了分析,报告了西部各省域物流业发展现状及其与经济发展关系的现状。通过采用感应力系数和影响力系数,进行了区域物流业及其相关产业与区域经济间的相互影响调查,反映了西部各省区域物流业与经济关联度之间的互动特征及其动态变化趋势,取得西部省域地区物流业与区域经济互动关系并不显著的基本结论,西部各省市区的物流业发展现状与经济发展水平不同,导致两者之间关系在不同省域存在明显的差异;西部区域物流业与区域经济的影响力系数和感应力系数在产业间不同,地区间也存在着差异,应当探索符合区域自身特色的物流业发展战略,促进区域物流业与区域经济的互动平衡发展。  相似文献

With the increasing scarcity of natural resources, the ability to maintain quality standards during resource-scarce times becomes more critical for business performance. Theories on managing resource scarcity cannot be easily tested in contexts where resources are still abundant. This study therefore turns to an emerging market context in which natural resource availability naturally varies strongly between seasons, namely, that of Ethiopian pastoralists who for many generations learned to adapt to natural resource scarcity. Central to our theory is the natural resource deployment capability, which is the ability of a business to make efficient and effective use of available resources to maintain business performance during resource-scarce times. Using three-wave longitudinal data from 120 pastoral family-based livestock businesses, the study shows that when resources are scarce or extremely scarce, market knowledge helps to better deploy the scarce natural resources, leading to higher product quality. The findings imply that businesses with a better understanding of markets have stronger natural resource deployment capability. The lesson for businesses that are confronted with approaching resource scarcity is therefore to strengthen their ability to deploy resources efficiently and effectively by strengthening their market knowledge in which such capability is rooted.  相似文献
