外国直接投资与我国对外贸易的实证研究

目前关于外国直接投资(FDI)与一国出口贸易间关系的研究已由最初的定性向定量发展,但多数定量分析集中在直接投资与出口的相关因果关系上。本文则利用我国改革开放以来到加入世贸组织之前的数据,对FDI与我国的出口规模、出口产品结构、出口产品竞争力等进行相关性分析。     

论广州新会展中心的形成对广州酒店业的影响

广州会议、会展业对广州酒店业的经营影响巨大，尤其是每年两次的交易会给当地酒店带来了大量的客源。随着经济的发展，新会展中心的形成，将使广州的酒店业在需求总量上进一步扩大，但酒店之间的竞争格局会发生改变，尤其是高档酒店之间的竞争会更加激烈，在酒店布局上，形成酒店的东进、南移的新局面。     

供应链库存系统网格环境中的控制研究

供应链库存系统由于其分散性及平台的异构性,使库存控制的理论研究在实践应用中受到很大限制。网格技术为该问题的解决提供了一种有效的方法。在供应商管理库存理论和网格体系结构的基础上,构建了供应链库存系统控制网格环境中的集成框架,实现了基于网格技术的集成框架供应链库存的实时控制和安全库存量的有效降低。

一些领先的企业从售后服务领域获取高达50%的利润收入,售后服务管理已成为企业的决策焦点。可通过对消费者的服务需求预测、产品设计、新技术应用和企业联盟等策略来满足消费者的各种需求,降低配件的库存水平、减少服务成本,以充分挖掘售后服务领域潜在的利润空间。     

存货质押融资业务中外比较分析及案例研究

积极发展存货质押融资业务是改善我国中小企业融资难的一条有效途径。为促进这一业务的发展,本文系统地比较分析了国内外存货质押融资的异同,认为我国存货质押融资业务现阶段虽然通过物流与金融的有效整合取得飞速发展,但与国外多年积累的经验和先进的业务控制水平相比,无论在制度环境、行业环境、业务基本要素和控制方式等四个方面都需要系统改善。     

航空客运收益管理中的渠道管理问题研究

传统的存量控制研究的解决方案是以直接面对最终顾客为前提的,没有将销售渠道的需求分布考虑在内,因而也就不能把分配给各个销售渠道的机票数量进行科学控制和优化。不同的销售渠道对同种类型机票的需求分布不同,并且给航空公司带来的最终收入不同,因此,随着联网售票系统的完善和电子商务的发展,如何更好地管理销售渠道,给那些能给航空公司带来更多收益的销售渠道预留足够的座位,已经成为航空公司不容忽视的问题。     

存货质押融资分阶段利率决策模型的构建

随着保理融资各交易阶段的进行,保理商所承受的风险相对由高至低,保理商利润非负的临界质押率水平及利率水平都发生了相应的动态变化。从价格波动规律出发,以进出口保理融资业务为代表,在满足下侧风险限制条件下,提出保理商针对各交易阶段提供融资业务利率的决策模型,并在此基础上分析保理融资中质押率、价格、违约可能性与利率的相互关系。研究得出利率水平随着各交易阶段的进行呈逐渐降低的趋势,灵活把握融资各阶段质押物价值、违约等风险因子变化,有利于降低融资风险性。     

Exploring the dynamic spillover of cryptocurrency environmental attention across the commodities,green bonds,and environment-related stocks

We analyze the dynamic spillover impact of cryptocurrency environmental attention (ICEA) on three asset classes: commodities, green bonds (GBs), and environment-related stocks. Our wavelet-based analysis suggests that ICEA is sharply escalated after the first quarter of 2021. During this period of intense attention, only the soybean commodity and Solactive GB tend to move positively and negatively with ICEA, respectively. Accordingly, the clean energy, sustainability, and Environmental, Social, and Governance (ESG) stock indices are positively associated with ICEA during 2018–2019 at the medium frequency bands. In most periods and frequency domains, most commodities, GBs, and environment-related stocks are not strongly linked to ICEA. Moreover, Diebold and Yilmaz’s (2014) spillover estimations signify no strong spillover effect of ICEA on the asset classes considered in this study. These findings are further corroborated by the wavelet-based Granger causality analysis. Moreover, our quantile regression (QR) estimations suggest that most assets are adversely influenced by ICEA, depending on the market conditions. Our research conveys some novel and vital policy ramifications to both investors and policymakers.     

Investigating the Effects of Daily Inventory Record Inaccuracy in Multichannel Retailing

Inventory record inaccuracy (IRI) challenges multichannel retailers in fulfilling both brick‐and‐mortar and direct channel demands from their distribution centers. The nature and damaging effects of IRI largely go unnoticed because retailers assume daily IRI remains stable over time within the replenishment cycle. While research shows that a high level of IRI is damaging, in reality the level of IRI can change every day. We posit that daily IRI variation increases the uncertainty in the system to negatively affect inventory and service levels. Our research uses data collected daily from a multichannel retailer to ground a discrete‐event simulation experiment. Going beyond testing just the level of IRI, we evaluate daily IRI variation's impact on operating performance. What we find in our empirical data challenges extant assumptions regarding the characteristics of IRI. In addition, our simulation results reveal that daily IRI variation has a paradoxical effect: it increases inventory levels while also decreasing service levels. Moreover, we also reveal that brick‐and‐mortar and direct channels are impacted differently. Our findings show that assumptions and practices that ignore daily IRI variation need revising. For managers, we demonstrate how periods of multiday counting help assess their daily IRI variation and indicate what the causes may be.     

"后金融危机时代"外贸企业的现金流控制

现金流对于外贸企业而言生死攸关,然而传统的财务记账方式一定程度上不能及时、有效地反映外贸企业在货币汇兑中的损益。在目前经济尚未完全复苏的情况下,外贸企业的现金流控制成为至关重要的问题。
