Capability hierarchy in electronic procurement and procurement process performance: An empirical analysis

This paper examines the interrelationship between two hierarchically structured functional capabilities pertinent in the organizational procurement process, and the impact of these capabilities on procurement process performance. These functional capabilities operate at different levels in an organization's procurement process. We draw upon resource- and knowledge-based views of the firm to theorize that in this hierarchy of information technology-enabled procurement capabilities, the higher-level capability – procurement integration competence – enables firms to develop and deploy a lower-level capability – digital procurement competence. Further, we theorize that the lower-level capability impacts procurement process performance directly and completely mediates the relationship between higher-level capability and performance. Thus, although performance is impacted directly only by the lower-level capability, the higher-level capability facilitates the development and use of the lower-level capability. Our research model is tested using survey data from a large sample of 412 manufacturing firms. The results provide strong support for the proposed research model. In particular, we find that as hypothesized, the impact of procurement integration competence on performance is completely mediated by digital procurement competence. Our results suggest that when examined at the procurement process level, the impact of higher-level capabilities may be manifested completely through the lower-level capabilities. Theoretical and practical implications of the research are discussed.     

Electronic Computers – The Challenge to Management

The potentialities of computers have not been fully exploited in the U.S. because management has underestimated the task of putting them to proper use. Management has believed that computers themselves are automation. But automation places a premium on good management. Without careful management planning, business resources are wasted in terms of managerial and technical time and abilities. Since computers are capable of handling many tasks simultaneously, it is only by casting aside the departmental concept and substituting the integrated systems approach that the true value of these machines begins to be appreciated. Automatic data processing provides for the tighter control that is important in competitive markets. The key to the whole problem of putting automation to work is education of personnel. Knowledge of equipment and techniques is not enough. Automation, by permitting handling of many jobs simultaneously, is in direct conflict with the concept of division of labor. The businessman, faced with wholesale reorganization of work, must train more basically and broadly. Current training for this field is largely dependent upon specialized courses offered by the manufactures of computers. The responsibility for training these people is largely that of private business, and it is a larger task than most managers realize. If a businessman is to feel confident that his company’s data processing is not just a gamble, he must accept this new challenge to management.

试论我国电子商务发展的对策措施

随着计算机技术、网络技术和通讯技术的发展和应用,商务活动的国际化、信息化和无经纸化已成为各国商务发展的潮流,电子商务作为一种全新的商务方式应运而生,掀起一场全球性的贸易革命。我国在电子商务发展中应该采取积极的对策措施,以期引起有关部门、企业等的关注,共同推动我国电子商务的快速发展。     

我国通关监管现代化与贸易便利化——基于中国背景的分析

随着经济全球化进程的加快,国际贸易迅猛发展,企业要求贸易便利化的呼声也日渐高涨.目前WTO对贸易便利化的关注主要集中在海关和跨境制度上,特别是在国际物流新发展和"零库存"等经营方式对"无障碍通关"的要求下,对海关通关监管效能提出了更高的要求.在这种形势下,海关作为国家进出境监督管理机关,面对飞速增长的业务量和相对有限的监管资源,如何积极应对贸易便利化对现代海关通关监管工作提出的要求,实现"严密监管"与"便捷通关"的平衡统一,是中国海关面临的重大课题.     

Using online opinion leaders to promote the hedonic and utilitarian value of products and services

Research and applied evidence suggest that online opinion leaders are important promoters of products and services. However, managers and firms need to choose which opinion leaders to work with and better understand how to collaborate with those leaders to promote different types of products and services. Online opinion leaders should be used to promote the experiential (hedonic) and functional (utilitarian) value of products and services over different online forums. In this article, we describe how online opinion leaders can serve appeal leadership functions, serve knowledge leadership functions, and take multiple roles (e.g., experts, celebrities, micro-celebrities, micro-influencers, early adopters, market mavens, enthusiasts). We then present a five-stage planning process designed to guide partnerships with online opinion leaders. Specific steps in the process include: planning (setting the objectives of the campaign and the role of online opinion leaders), recognition (identifying influential and relevant online opinion leaders), alignment (matching online opinion leaders and online forums with the products or services promoted), motivation (rewarding online opinion leaders in a way that aligns with their social role), and coordination (negotiating, monitoring, and supporting the influence of the online opinion leaders).     

Effective electronic menu presentation: From the cognitive style and mental imagery perspectives

While technology has significantly changed how we communicate, our knowledge of how to utilize electronic menus in restaurants is lacking. This study aims to fill this gap by investigating customer response to various multimedia presentation formats on a digital platform. To test this, we developed four menu presentation formats and examined how different presentation formats affect mental imagery and the desire to eat. The results reveal that mental imagery positively affects the desire to eat, while mental imagery itself varies depending on the presentation format and cognitive style. The video menu elicited the highest mental imagery followed by the picture, narration, and conventional menus. Visualizers and verbalizers appear to form similar mental imagery with these presentation formats. Providing support for dual coding theory, the results suggest that while the visual domain plays the strongest role in mental imagery and the desire to eat, they are also influenced by auditory stimuli.     

Comparing email and SNS users: Investigating e-servicescape,customer reviews,trust, loyalty and E-WOM

For better or worse, satisfied or dissatisfied customers function as trusted branding faces for organizations as they transmit potentially viral messages through E-WOM. These E-WOM messages can prove marketers' best friends or worst enemies, depending on their tenor. With data from actual customers of an e-tailer, this research enriches our understanding of how e-servicescape is linked to E-WOM. E-servicescape captures the online environmental factors of marketers’ websites. Two forms of E-WOM are examined; i.e., emails and social network postings. Customer reviews were investigated as a prospective sub-dimension of e-servicescape. Findings suggest that customer reviews play an integral role in the e-servicescape construct, that e-servicescape positively impacts trust and that trust positively influences E-WOM and customer loyalty. Two groups of customers were compared, and results indicated differences between email and SNS users. Theoretical and managerial insights related to E-WOM and electronic commerce shopping behavior were generated.
