网络虚拟财产应受法律保护

网络虚拟财产是在智力劳动的基础上形成的,可以用金钱货币购买的主要存在于网络世界中的财产,具有财产属性和价值。网络虚拟财产虽然存在于无形的网络中,是虚拟的,但又是客观存在的事物,是现实生活中财产的另一种存在形式,它们应该被法律加以认可,并依靠法律来调整,以保护网民的合法权益。     

Following the breadcrumbs: An analysis of online product review characteristics by online shoppers

Consumer-generated product reviews are a driving force behind online purchases; at the same time, unfavorable reviews can discourage interested online shoppers and eventually hurt the brand. The objective of this exploratory study was to analyze a diverse range of characteristics and the valence of online product reviews that would aid in responding to customer dissatisfaction. Product reviews (N = 1982) from Amazon.com were collected and content analyzed. Some of the key findings include the following: (a) price was the most commonly discussed product feature; (b) online shoppers found two-sided reviews to be most informative, contradicting the commonly held assumption that negative reviews were more informative and diagnostic in nature; and (c) ‘no action’ was the most common end action across two-sided and negative reviews, indicating that varying levels of dissatisfaction might not always lead to a negative end action. Implications for marketers are discussed.     

客户金融化与企业研发投入——基于中国上市公司核心客户的经验研究

本文立足供应商企业,基于中国沪深A股非金融类上市公司2007~2018年披露的上市核心客户信息,理论分析与实证检验客户金融资产投资对其研发投入的影响,以考察客户金融化行为的供应链经济后果。研究发现,客户企业金融资产投资对企业研发投入具有显著的正向影响,且随着企业的客户依赖度与商业信用规模的增加而呈现递减的趋势,表明企业认为客户金融化行为是出于预防储备的“蓄水池”动机,有助于降低企业感知的客户经营风险,促进其研发投入增加。基于中国制度背景的进一步分析发现,客户为国有控股以及客户所处地区市场化程度较高时,上述关系表现得较弱,表明该促进效应还要受到客户国有产权性质与所在地区市场化程度的干预。     

考虑产权属性的发电商投资阈值模型及其分析

论文在考虑发电商电力报价与二次成本函数的基础上,基于发电商的边际效用,建立了产权属性条件约束下的发电商最优投资阈值模型;分析结果表明:完全市场竞争条件下,发电商最优投资阈值与其产权属性因子存在正向关系,产权属性因子值越大,发电商最优投资阈值越高,发电商越具有民营性质,反之,发电商越具有国有属性,且国有发电商的投资积极性比民营发电商高,这与经济学原理和我国电力经济生活相一致。     

框架效应对冲动性购买行为的影响研究

采用2×2×2的实验设计分析框架效应和调节定向对冲动性购买行为的影响。研究发现,正面的属性框架和负面的目标框架下皆有助于提高冲动性购买的程度;调节定向会干扰框架效应对冲动性购买行为的影响效果;当消费者为促进定向时,正面属性框架下的冲动性购买程度更高;促进定向的消费者在正面目标框架下的冲动性购买行为明显增强,而防御定向的消费者在负面目标框架下的冲动性购买行为会明显增强。     

论用社会主义核心价值体系引领资本二维属性的协调运行

资本具有物的属性和社会关系属性。透过资本物的属性,可以呈现资本运行过程中,市场主体之间纷繁复杂的经济关系。在以往关于资本的研究中,资本物的属性被强化,而社会关系属性被弱化。如果只看到资本物的属性,资本运行就会加剧资本与人关系的紧张、资本与社会关系的紧张,导致经济关系系统的紊乱。用社会主义核心价值体系引领资本运行,就是要全面把握资本物的属性和社会关系属性,引导市场主体之间建立良性和谐的经济关系,促进资本良性运行,和谐发展,造福人民。     

An Interactive Approach to Multiple Attribute Group Decision Making with Multigranular Uncertain Linguistic Information

The multiple attribute group decision making (MAGDM) problems having multiple sources of uncertain linguistic information assessed in different linguistic label sets are investigated. The existing linguistic labels in a linguistic label set are uniformly and symmetrically distributed, but in many real-life situations, the unbalanced linguistic information appears due to the nature of the linguistic variables used in the problems (Herrera and Herrera-Viedma, Proceedings of 4th international workshop on preferences and decisions, Trento, Italy, 2003). In this paper, we first define some unbalanced linguistic label sets, and then develop some transformation functions to unify the given multigranular linguistic labels in a unique linguistic label set without loss of information. Moreover, we utilize the uncertain linguistic weighted averaging operator to aggregate all individual uncertain linguistic decision matrices into a collective one, and define two similarity measures, one for measuring the similarity degree between each pair of uncertain linguistic variables, and the other for checking the consensus degrees among the individual uncertain linguistic decision matrices and the collective uncertain linguistic decision matrix. Finally, we develop an interactive approach to MAGDM with multigranular uncertain linguistic information and illustrate the developed approach with an application example.     

国有企业经营目标的演进和定位

国有企业经营目标经历了产品产量和产值最大化、满足社会需要和追求利润的双重目标、利润最大化等阶段.企业是市场经济的微观基础.国有企业重塑为市场经济主体,就是把多数国有企业改造成为与其他企业无差异的法人实体和竞争主体,对市场信号能够主动作出反应.企业的市场属性是基本属性.依此划分,分为完全市场属性企业、市场属性较强但又不完全的企业、具有市场属性但国家需控制的企业、属政府行为延伸的市场属性最弱的一类企业.新的国有资产管理体制是由一个多层次委托--代理关系组成的系统.委托--代理关系把一切都改变了,由直接到间接、由上下级的信任关系为利益委托关系.企业的经营目标,也理所当然地由利润最大化转变为企业价值最大化.
