In the e-Retail industry, a well-designed IT infrastructure is essential in creating a tightly integrated value chain and delivering high quality service. With intense competition for market share and profits, information systems and technology (IST) sourcing decisions are becoming increasingly important to e-Retail firms to support continued growth and market responsiveness. Drawing on the contingency theory, we examine organizational and environmental factors that influence an e-Retailer's IST sourcing strategy of make versus buy in enabling its value chain activities, and we also look at firm-level performance impacts of IST sourcing decisions that involve bundling across value chain activities. We test the proposed model and hypotheses using a panel data set of 307 firms over the period of 2006–2010. The results show that firms that make transformative IT investments tend to source a smaller portion of IST for their e-Retail value chain activities than firms that pursue automate or informate as their strategic role for IT investment. Capabilities are positively associated with IST sourcing. Firms experienced in e-Retail are more likely to build rather than buy their IST. In addition, we find mimicking behavior for IST sourcing among firms in the same merchandizer category. We find that IT strategic role is strongly associated with growth metric, whereas sourcing decisions predominantly impact operational performance measures. There is partial evidence that alignment between IT strategic role and IST sourcing decisions results in better performance effects. Moreover, complementary IST sourcing of synergistic marketing and sales activities positively impacts Web sales and conversion rate, but the sourcing combination of logistics, operations, and sales activities is associated with lower Web sales and conversion rate. 相似文献

This paper presents a series of models that can be used to find weekly schedules for therapists who provide ongoing treatment to patients throughout a geographical region. In all cases, patient-appointment times and visit days are known prior to the beginning of the planning horizon. Variations in the models include single vs. multiple home bases, homogeneous vs. heterogeneous therapists, lunch break requirements, and a nonlinear cost structure for mileage reimbursement and overtime. The single home base and homogeneous therapist cases proved to be easy to solve and so were not thoroughly investigated. This left two cases of interest: the first included only lunch breaks while the second added nonlinear overtime and mileage reimbursement costs. For the first case, 40 data sets were solved, each consisting of either 15 or 20 therapists and between roughly 300 and 540 patient visits over five days. For each instance, we were able to obtain the minimum cost of providing residential healthcare services using a commercial solver. The results showed that CPU time increases more rapidly than total cost as the total number of visits grows. For the second case, which was much more difficult, it was necessary to develop heuristics to find good solutions quickly. Results for 5- through 20-therapist instances are presented and compared to the linear programming relaxation lower bounds. In the first of two parametric analyses, the tradeoff between the number of therapists on staff and the cost of providing service was examined. In the second, a similar tradeoff was explored between cost can the number of home bases used by the therapists. 相似文献

China is currently the largest CO2 emitter in the world and demonstrates one of the highest levels of energy consumption. The sustainable consumption behavior has increased in China, especially in urban cities. Some clear evidence of this includes food purchasing behavior. Recent studies have also suggested that considering full product information transparency, consumers are willing to pay premium prices for products. With this in mind, sustainable consumption must still be facilitated by related policies, regulations, and tools. This study focuses on sustainable consumption behavior in China and collects and analyzes the literature from the last decade (2007–2017) on the topic. In so doing, it highlights new trends and research topics against the background of circular economy development. The method of systematic review is applied. The review is categorized into several main groups: national policies and regulations, the green awareness of consumers, the definition of related concepts, the barriers between sustainable consumption and the circular economy, and the indicators for circular economy assessment in China. Future research directions are discussed. Furthermore, future challenges are addressed from three perspectives: sustainable consumption facilitating the circular economy, “cradle‐to‐cradle” practices, and the link between the European Union and China. This is a fundamental study in the research domain of sustainable consumption behavior. It provides added value that benefits both academic researchers and decision makers. It also sheds light on the further study of sustainable consumption behavior in China from a macroeconomic perspective. 相似文献

确定股权回报率是进行长期投资决策的关键步骤,但在现实非理性世界中难以直接运用传统财务理论所推荐的资本资产定价模型来确定股权回报率。针对FAR与NEER方法,本文首先探讨这两类方法的理论依据并揭示其本质内涵,然后说明:在非理性世界中,如果上市公司管理者追求公司价值最大化目标,那么就应该基于公司项目的基本风险来确定股权回报率;相反地,如果管理者追求近期股价最大化,那么就应该基于市场投资者的预期来确定股权回报率。 相似文献

This article examines China's approach to industrial consultation by examining six tripartite bodies at the national, provincial and county levels. It argues that the institutionalisation of tripartitism is consistent with China's overall approach to market reform being characterised by experimentalism, gradualism, dynamism and a gradual softening of party domination. Despite limitations, it is accepted that China is building a transition tripartite system that is bolstering the autonomy and representational capacity of the social partners. 相似文献
