This study aims to investigate the role of interfunctional collaboration between marketing and purchasing functions in industrial companies. Interfunctional collaboration is considered as a measure of the internal alignment and partnership between departments in the firm, which in turn contributes to the creation of sustainable advantages via improved external partnerships and facilitating demand chain integration. We test the impact of customer orientation as well as the interactions between departments (specifically marketing and purchasing) as collaboration antecedents, and analyze the direct impact of marketing-purchasing collaboration on business performance. The model is tested on a sample of 148 industrial companies in Russia with two key respondents in each firm, incorporating the purchasing as well as the marketing perspective. The results show that marketing-purchasing collaboration mediates the effects of interfunctional interaction as well as customer orientation on business performance. Alternative model testing shows that the direct effects of these antecedent constructs on performance are non-significant in the context of Russian industrial companies.  相似文献

In this paper, we developed a new model of oligopolistic competition for fashion supply chains in the case of differentiated products with the inclusion of environmental concerns. The model assumes that each fashion firm's product is distinct by brand and the firms compete until an equilibrium is achieved. Each fashion firm seeks to maximize its profits as well as to minimize its emissions throughout its supply chain with the latter criterion being weighted in an individual manner by each firm. The competitive supply chain model is network-based and variational inequality theory is utilized for the formulation of the governing Nash equilibrium as well as for the solution of the case study examples. The numerical examples illustrate both the generality of the modeling framework as well as how the model and computational scheme can be used in practice to explore the effects of changes in the demand functions; in the total cost and total emission functions, as well as in the weights.  相似文献

We examine the strategic interests of ASEAN countries within APEC when forming regional trading arrangements in the pursuit of trade liberalization. Employing a Computable General Equilibrium (CGE) model, the effects of ASEAN's various Free Trade Area arrangements with the U.S., Northeast Asia as well as APEC are analyzed. The impact on ASEAN as a whole as well as for each individual member coutry is examined. A free trade area with the U.S. is likely to benefit the Philippines and Indonesia most.  相似文献

Sponsorship B2B relationships generally are entered into by sponsors seeking brand-related benefits through association with a sport entity brand. Negative incidents involving athletes representing the sport entity may threaten the brands of both the sport and sponsor and can weaken or even dissolve the partnership. The management of these episodes is critical in protecting the sport entity's brand equity, as well as the sponsor's brand, and ultimately the relationship. This study explores multiple stakeholders' perspectives on these degenerative episodes and the potential relational outcomes using a series of depth interviews with major sponsors and sport entities. We identify key constructs such as attribution of blame, societal norms, zone of tolerance and perceived severity which influence whether this behavior acts as a degenerative episode in the relationship. Factors such as existing relationship quality and episode management can affect the impact on the relationship as well as the extent of relational change.  相似文献

For many years, the employment relations (ER) literature took the perspective that employee voice via trade unions could channel discontent and reduce exit, thereby improving productivity. In organizational behaviour (OB) research voice has also emerged as an important concept, and a focus of this research has been to understand the antecedents of the decision of employees to engage or not engage in voice. In OB research, however, voice is not viewed as it is in ER as a mechanism to provide collective representation of employee interests. Rather, it is seen as an expression of the desire and choice of individual workers to communicate information and ideas to management for the benefit of the organization. This article offers a critique of the OB conception of voice, and in particular highlights the limitations of its view of voice as a pro‐social behaviour. We argue that the OB conception of voice is at best partial because its definition of voice as an activity that benefits the organization leaves no room for considering voice as a means of challenging management, or indeed simply as being a vehicle for employee self‐determination.  相似文献

The history of technology can play an important role in illuminating the fundamentals of technological change, but it is important that technology teachers, teacher educators, curriculum developers and researchers can be provided with good analytical tools for this purpose. In this article, we propose a model of techno-historical interplay, as a help in deciding what historical artefacts and systems should be included in technology curricula and teaching as well as in analyzing and conveying to students the fundamental issues of technological change. We want to emphasize particularly three points of importance in employing the model as a tool of analysis. First of all, it is crucial to decide what one wants the technologically literate student to know about technology and technological change. This should include an awareness of the historical and geographical contingency of any technology. Second, on the basis of this decision one should adapt the model as a tool for selecting relevant technologies. Third, the model should be applied as an instrument of analysis of the history of the selected technological artefacts or systems as well as theories of technological development.  相似文献

The paper examines the main economic and institutional incentives which have driven major OECD food retailers in their use of private voluntary standards and discusses their growing role in shaping the agri-food system. It is based on interviews with quality and safety directors of major OECD retailers and a brief survey of retailers’ actual buyer practices. Though not all retailers are included, these firms account for over 70% of retail food sales in OECD countries. We find that the growing voice of civil society, changing legal and institutional frameworks, increased market concentration and buying power as well as their integration with financial markets has provided the setting for development of private standards. While food safety and quality standards are seen as key to maintaining and improving reputation as well as against legal liabilities, additional standards such as labour, environmental and animal welfare are also gaining ground as strategies for customer loyalty and market shares. The grass-roots retailer move in the harmonization of food safety standards is seen as an initial step towards a global approach to managing the food system, with harmonization of other standards likely in the future. Given their buyer power, these developments can be viewed as a way of governing the food system and will be important for both OECD and non-OECD food and agricultural sector evolution in the coming years.  相似文献

Assessing value-in-use: A conceptual framework and exploratory study   总被引:2,自引:0,他引:2  
Developing approaches for understanding customer perceived value is a priority for managers and scholars alike. A conceptual framework for assessment of value-in-use is proposed and explored within the context of a maintenance service provider. In contrast to value models in previous empirical research, the framework includes assessment not just of provider attributes but also of the customer's usage processes, as well as customer evaluations of the value-in-use they obtain. Interviews with members of a cross-disciplinary buying group provide support for the framework, including the observations that individuals can assess the quality of their usage processes and that they can articulate value-in-use at both organisational and individual levels; the further concept of network quality also emerges from the data. Assessment of usage process quality as well as service quality evolves as the customer's goals evolve. Practitioners may wish to elicit usage process quality and value-in-use as well as service quality. Research directions include scale development for both usage process quality and value-in-use.  相似文献

The spread of innovation is usually characterized as a diffusion process. This article suggests that there may be some value in viewing this important phenomenon in terms of the mathematical construct known as percolation theory. J. Mort writes that phenomena and concepts such as induction periods, critical percolation thresholds, discrete propagation media, site coordination, clusters, and connective constants all have remarkable analogs in the generally observed features of product innovation. This phenomenological perspective, in which the customer emerges naturally as the controlling factor in the spread of innovations, may account for specific marketing approaches that have facilitated successful innovations such as the Xerox 914 copier. The approach may prove especially relevant in describing the spread of certain information, communication-based innovations, such as the explosive growth in facsimile (FAX), and other network-based products, as the utility and value of such products to the customer is inherently linked to the extant degree of connectivity.  相似文献

We examine how new biotechnology firms (NBFs) select pharmaceutical firms as R&D allies as a function of value creation and value appropriation considerations. We develop a theoretical framework to understand partnering decisions accounting for both, a potential partner's ability as well as incentives to appropriate and create value within an R&D alliance. Our empirical findings show that NBFs are more likely to ally with pharmaceutical firms with the ability to create value, as long as these firms have the incentives to use their skills to create rather than appropriate value. Our study highlights the double‐edged sword nature of value creation skills and provides a deeper understanding into the contextual factors that determine when potential R&D partners will perceive such skills as increasing appropriation risks.

Rental Price Adjustment and Investment in the Office Market   总被引:3,自引:0,他引:3  
This study presents estimates of the rental price adjustment mechanism and investment response in the office construction market using data from fourteen cities over the period 1979–1983. Market rents are seen to adjust in response to local as well as national economic conditions. Investment, as measured by building permits, responds strongly to rent in a two-stage regression model, as well as to the long-term growth rate of office employment. Tests for a cobweb-type overreaction by investors do not reveal any cyclical characteristics of the market, indicating that the effects of random demand shocks are not felt beyond the normal construction period.  相似文献
