多重匹配下柔性人力资源管理构型与组织成长性绩效

基于构型观和动态能力理论,借鉴“结构（管理构型）—行为（柔性能力培育）—绩效（组织绩效）”经典范式,构建“柔性人力资源管理构型—技能延展力—成长性绩效”的理论框架。对486份企业中高层管理者调查问卷进行结构方程分析,结果表明：①因循多重匹配理念,人力资源管理构型能够凝练出3种典型柔性管理模式：内柔导向型HRM、外柔导向型HRM、内外兼柔导向型HRM;②差异化柔性人力资源管理构型（内柔导向型、内外兼柔导向型、外柔导向型HRM）正向影响组织成长性绩效;③技能延展力在柔性人力资源管理构型与成长性绩效之间起部分中介作用。技能延展力在内柔导向型、内外兼柔导向型、外柔导向型HRM与成长性绩效之间的中介作用依次降低。

The multiple unit auction with variable supply

Summary. The theory of multiple unit auctions traditionally assumes that the offered quantity is fixed. I argue that this assumption is not appropriate for many applications because the seller may be able and willing to adjust the supply as a function of the bidding. In this paper I address this shortcoming by analyzing a multi-unit auction game between a monopolistic seller who can produce arbitrary quantities at constant unit cost, and oligopolistic bidders. I establish the existence of a subgame-perfect equilibrium for price discriminating and for uniform price auctions. I also show that bidders have an incentive to misreport their true demand in both auction formats, but they do that in different ways and for different reasons. Furthermore, both auction formats are inefficient, but there is no unambiguous ordering among them. Finally, the more competitive the bidders are, the more likely the seller is to prefer uniform pricing over price discrimination, yet increased competition among bidders may or may not enhance efficiency.

中国农业企业汇率风险应对行为的实证研究——基于企业竞争力视角

本文提出了一个涉外企业汇率风险应对行为的分析框架,并利用352家涉外农业企业调查数据与多元Logit模型,从企业竞争力视角实证检验中国农业企业汇率风险应对行为的影响因素。研究发现,企业竞争力对中国农业企业避险策略选择至关重要,且表征企业竞争力的诸多变量对汇率风险应对行为的影响各不相同:融资能力越强、在技术方面越有优势的农业企业越倾向于使用运营策略规避汇率风险,而国际化程度越高的农业企业越倾向于使用金融衍生工具管理汇率风险;同时,农业企业汇率风险应对行为存在较为明显的地区差异。在此基础上,本文提出中国涉外农业企业应对汇率风险、扩大出口的若干政策建议。     

区域耕地数量变化预测方法的对比研究

研究目的:对区域耕地数量变化预测方法进行对比分析,科学合理确定区域耕地数量。研究方法:通过Pearson相关分析法筛选影响耕地变化的关键因子,利用改进的BP神经网络算法、灰色模型和多元线性回归模型法对费县耕地数量变化进行预测。研究结果:改进的BP神经网络算法相对传统的灰色模型和多元线性回归模型等预测方法具备较高的预测精度。研究结论:改进的BP神经网络算法是进行耕地数量变化预测的较好方法,具有实际指导意义,其预测结果可以为当地相关部门合理地确定耕地保有量、推进耕地保护提供科学依据。     

Strategic product showcasing mode of E-commerce live streaming

E-commerce live streaming can considerably help brands improve sales dynamics, but it is multiple dilemmas in choosing suitable e-commerce live streaming product showcasing modes. To address the multiple dilemmas, we first employ the Stackelberg game to depict three e-commerce live streaming product showcasing modes: brand self-live streaming, influencer-led live streaming mixture, and influencer-led special live streaming. Second, we analyze the relationship between choices and game parameters, including live streaming stimulus sensitivity, unit service quality improvement cost, and service sensitivity. Meanwhile, through the comparative analysis of the three modes, we get the optimal threshold of each mode. Last, we conduct a case study comparing Chinese apparel and accessories brands Hodo and RUANS to verify the above relations. The results suggest that: (i) the more sensitive consumers are to live streaming stimulus, the more beneficial it is for the brand manufacturer to employ special live streaming, while the increase in unit service quality improvement cost will harm the brand manufacturer; (ii) the fixed participation fee determines the choice of e-commerce live streaming product showcasing modes; (iii) e-commerce live streaming product showcasing modes can help brands to optimize their decision-making.
