While personal data is invaluable to firms, the drivers of e-commerce customers' willingness to disclose their personal data remain tenuous. Using social exchange theory, we develop a model that explores the impact of consumers' perceived benefit, and relative power, on store trust, in turn driving their willingness to disclose their personal data. We collected our empirical data using a representative online survey, with the results being analyzed by using structural equation modeling. The results corroborate that (a) consumer-perceived e-commerce store trust drives their willingness to disclose their personal data, and (b) perceived e-commerce provider reciprocity outweighs consumers’ perceived data disclosure benefit, suggesting the existence of symbolic (vs. purely instrumental) social exchange.  相似文献

在政府给予绿色补贴的情况下,考虑企业销售努力对绿色供应链决策的影响.以一个制造商和零售商构成的二级绿色供应链为研究对象,建立制造商主导和零售商主导的不同权力结构下的绿色供应链决策模型.通过对比分析不同模型决策,进一步采取算例分析进行验证,为企业实施绿色供应链管理提出相关建议.研究结果表明:政府绿色度补贴系数改变了产品绿色度、批发价格、销售努力、零售商利润、制造商利润以及供应链总体的利润;销售努力的投入会影响产品的批发价格以及零售商利润;无论是否考虑销售努力,集中决策下,供应链的效率总是大于分散决策下的效率;零售商主导的分散决策下,供应链效率高于制造商主导时的供应链的效率.  相似文献

Disruptive innovation dramatically changes the demand of a product market in the information technology (IT) industry. In response to the impact of disruptive innovation, IT firms that may be eliminated from the competitive race actively develop innovative products and adjust their operating strategies to strengthen their survivability in the fiercely competitive market. Thus, this study explores the factors that affect firm value in the IT industry under the impact of disruptive innovation. The empirical results reveal that knowledge capital and CEO power play crucial roles in explaining firm value. IT firms with powerful CEOs and increased knowledge capital have high firm values. The effects of knowledge capital and CEO power on firm value are especially significant for founder and duality CEO firms. Furthermore, the influence of CEO power is more prominent in periods of financial crisis.  相似文献

2010年开始,向基层赋权作为行政体制改革的重要内容在全国范围铺开。从权力义务视角对其进行研究有现实的必要性。赋权的核心是行政权力的转移,以权力转移过程中涉及的诸要素为切入点,可以分析出多重权力关系和有关主体在其中的权力义务。在此基础上,通过保障行政相对人对于赋权的参与权、设计上级行政机关实施赋权的制度、消除上级行政机关赋权的依据问题和设计基层行政机关行使权力的制度等方式完善向基层赋权,既使行政机关能够有效推进行政体制改革,又能对行政权进行有效规范、保障行政相对人权利。  相似文献

This research examines the effect of desire for exclusivity on evaluations of luxury experiences and proposes a boundary condition for the effect. The scarcity effect literature suggests that consumers prefer scarce products due to limited supply because they appeal to consumers’ desire for exclusive consumption. Building on this thesis, the current research argues that luxury experiences are intrinsically scarce enough to appeal to consumers’ desire for exclusivity: Consumers with a strong desire for exclusivity will evaluate luxury experiences more favorably than those with a weak desire for exclusivity. A pilot study confirms a positive correlation between consumers’ desire for exclusivity and attitudes toward luxury experiences. Study 1 demonstrates that consumers with a strong desire for exclusivity show more favorable attitudes toward luxury experiences than those with a weak desire for exclusivity. Further, Study 2 finds that consumers’ power state (powerful vs. powerless) moderates the effect of desire for exclusivity on their affinity for luxury experiences: Only when feeling powerful do consumers with a strong desire for exclusivity evaluate luxury experience more favorably than those with a weak desire for exclusivity. However, this is not the case when consumers feel powerless.  相似文献

Prior studies on power and interfirm learning in alliances have devoted limited attention to multiplicate influences of diverse power sources on exploration and exploitation and whether such influences on these two strategies are similar or different. This study investigates the joint effects of two types of perceived power—capability-driven power and position-driven power—on exploration versus exploitation in asymmetric alliances. Using a sample of 205 high-technology firms in China, the analyses suggest that each of the two types of perceived power separately has no direct effects on either exploration or exploitation. However, they complement (multiplicative effects) each other in promoting exploitation and exploration. Interestingly, the balanced effect of perceived position-driven power and perceived capability-driven power is positively related to exploration, while no such an impact is found in terms of exploitation. This study provides alternative insights about inter-organizational learning in asymmetric alliances and points out a direction for future research.  相似文献

We use a modified version of the stochastic frontier model to estimate oligopoly markups above the perfectly competitive frontier, separating out deterministic markups from purely stochastic markups. Using data from 42 US food processing industries between 1990 and 2010, empirical results indicate a widespread incidence of oligopoly power, with Lerner indexes averaging approximately 21%. Further, the estimated markups increase with industrial concentration but decrease with price elasticities and imports. Finally, the estimated Lerner indexes are in the range of previous food industry estimates using New Empirical Industrial Organization (NEIO) models.  相似文献

It is a wide-held assumption that professional development and change within purchasing and supply management (PSM) organisations can be explained and guided by a maturity model. In this paper the guidance which the maturity model concept offers to understand a PSM organisation's performance is assessed. The methodology is based on the outcomes of a literature review of PSM maturity models, development of an organisational change framework and the learning from three qualitative case studies. An alternative understanding of the development of the PSM organisation is offered through an organisational change framework, composing 1) movement transitions, 2) scalability of change, 3) acceptability of change, and 4) the substantive element of change. The research found that extant PSM maturity models are too rigid for PSM managers to apply, and although maturity models are commonly accepted in PSM literature, in practice, they may produce the opposite effect of what is promised. The PSM maturity models suggest that their application will lead to increased status and influence of PSM within the organisation; expectations that may not be met. PSM organisations’ change processes are subjected to a range of situational and contextual power relations which must be considered in order to advance the specific PSM organisation roles and responsibilities.  相似文献

In implementing its national strategy to achieve global leadership, China needs a new public administration theory that integrates political administration, economic management and social regulation. Even so, China has already started to promote its brand of political and economic development abroad. Therefore new comparative research and dialogue is called to explore the universality of Chinese and Western public administration ideas.  相似文献
