工业4.0驱动:基于制造企业智能化的股权结构实证研究

从投资者结构角度研究企业层面工业智能化的驱动力，用委托代理理论分析股权结构对企业智能化投资的影响。以中国制造业上市公司为研究样本，实证检验股权结构对企业智能化投资的关系。研究结果表明，从股权集中角度看，一定的股权制衡很有必要，一股独大不利于企业智能化投资；从企业性质看，公有企业更愿意进行智能化投资，个人私有的第一大股东不太愿意进行智能化投资；从激励角度看，高管薪酬与智能化投资之间的关系不明确，说明目前的薪酬激励制度不够合理；从地区文化角度看，越是发达的地区企业越容易接受智能化投资。     

基于银行理财顾客特征的产品模式创新研究

基于“感知利益”与“感知风险”权衡视角构建了银行理财顾客识别模型,将银行理财顾客划分为感知高利益—高风险敏感型顾客群体、感知低利益—高风险消极型顾客群体、感知低利益—低风险冷漠型顾客群体、感知高利益—低风险积极型顾客群体.应针对不同类型顾客群体的感知利益与感知风险对于购买意愿综合影响作用的差异、感知利益与感知风险构成维度重要程度的差异及人口统计特征和购买理财产品特征的差异,采取不同的提升感知利益且降低感知风险的创新产品模式.     

The Effects of Victim Anonymity on Unethical Behavior

We theorize that victim anonymity is an important factor in ethical decision making, such that actors engage in more self-interested and unethical behaviors toward anonymous victims than they do toward identifiable victims. Three experiments provided empirical support for this argument. In Study 1, participants withheld more life-saving products from anonymous than from identifiable victims. In Study 2, participants allocated a sum of payment more unfairly when interacting with an anonymous than with an identifiable partner. Finally, in Study 3, participants cheated more from an anonymous than from an identifiable person. Anticipated guilt fully mediated these effects in all three studies. Taken together, our research suggests that anonymous victims may be more likely to incur unethical treatment, which could explain many unethical business behaviors.     

A Brief Survey of Modern Optimization for Statisticians

Modern computational statistics is turning more and more to high‐dimensional optimization to handle the deluge of big data. Once a model is formulated, its parameters can be estimated by optimization. Because model parsimony is important, models routinely include non‐differentiable penalty terms such as the lasso. This sober reality complicates minimization and maximization. Our broad survey stresses a few important principles in algorithm design. Rather than view these principles in isolation, it is more productive to mix and match them. A few well‐chosen examples illustrate this point. Algorithm derivation is also emphasized, and theory is downplayed, particularly the abstractions of the convex calculus. Thus, our survey should be useful and accessible to a broad audience.     

产品市场定位与消费者忠诚之间的关系——基于浙江产品市场势力调查问卷

以2011年浙江省商务厅向各地市县发放的浙江产品市场势力调查问卷为数据来源,以其中的119家浙江省内商业企业作为研究样本,对浙江产品的市场定位与消费者忠诚之间的关系进行了实证研究。结果表明:产品市场定位与消费者的行为忠诚相关,提高产品的市场定位有利于消费者产生购买企业产品的偏好,进而促使消费者实现实际的、持续的购买行为;产品市场定位的提升尤其对产品客单价、产品销量和销售额的提升有显著的促进作用。因此,浙江企业应积极投入人力、物力,提高其产品的市场定位,以提升消费者忠诚,进而实现企业在市场中的议价能力及市场竞争力的提高。     

论金融危机下中国企业家的作为与责任

供应链的交易成本分析及供产双方的博弈

本文通过传统供应链中供应商和制造商的讨价还价模型分析,论证了交易双方的交易成本不同,造成供应商和制造商之间的相互依赖关系不同,从而双方的机会主义行为倾向也不同.制造商可以通过与高质量的供应商建立长期的诚信的战略合作伙伴关系,以减少为讨价还价消耗的交易成本,同时也减少了双方机会主义行为所造成的损害.

徐家围子断陷区营城组火山岩识别

勘探实践表明徐家围子断陷营城组火山机构是深层天然气藏良好的储集体。本文以徐家围子断陷中部营城组火山岩为研究对象,该区火山岩厚度大,爆发相、喷溢相和火山沉积相等各种相带均较发育,通过对火山岩地震反射特征的系统分析,总结了各种相带的具体震相特征。并以此为依据,应用趋势面属性、相干体分析技术等多种手段,对火山机构的空间分布进行了识别与预测,在营城组共识别出44个火山锥,对本区火山岩气藏的勘探开发具有一定的指导作用。
