The influence of firms' technological capabilities on export performance in supplier-dominated industries: the case of ceramic tiles firms 总被引:1,自引:0,他引:1
In this paper, we study the effects that firms' technological capabilities, as an expression of their technological innovation strategy, have on their international competitiveness. In doing so, we draw on export and international trade literature to justify the influence that the firms' technological activity has on their export performance. In addition, we use concepts derived from the literature on technological innovation to identify different capabilities that the firms may develop to manage their innovation process, i.e., those related to investment, production and co-operation. These constitute the basis of our hypothesis, in which the technological innovation capabilities identified are related to firms' export performance. Empirical work is carried out on a sample of 88 Spanish exporting firms belonging to the ceramic tiles industry, which is characterized as being a supplier-dominated industry. Data were mainly gathered through a postal survey directed at firm managers. Our findings show that technological innovation capabilities have a positive impact on export performance. Specifically, results show that investment in internal non-R&D innovative activities, such as engineering design and pre-production, exerts a positive influence on export performance. However, neither investment in R&D nor investment in external acquisition of technology exerts any influence on export performance. In addition, our findings show that production capabilities have a positive effect linked to both improvement and imitation of products and processes. Regarding co-operation, export performance is related to capabilities that derive from co-operation with universities and research institutes rather than co-operation with other companies. 相似文献

This paper examines recent research in student learning of technological concepts and processes. To explore this area three inter-related aspects are considered; existing concepts of technology, technological knowledge and processes. Different views of technology and technology education are reflected in both research outcomes and curriculum documents. Teacher and student perceptions of technology impact on the way in which technology is undertaken in the classroom. Teacher's perceptions of technology influence what they perceive as being important in learning of technology. student's perceptions of technology and technology education influence what knowledge and skills they operationalise in a technological task and hence affect student technological capability. Technological concepts and processes are often defined in different ways by particular groups. Subject subcultures are strongly held by both teachers and students. The influence of subject subcultures and communities of practice will be discussed in terms of defining and operationalising technological concepts and processes. Technological concepts are not consistently defined in the literature. For students to undertake technological activities, knowledge and processes cannot be divorced. Recent research highlights the problems when processes are emphasised over knowledge. This paper will examine different technological concepts in an attempt to create a critical balance between knowledge and process. Much of the literature in technology education has rightly emphasised definitions, curriculum issues, implementation and teacher training. This paper argues that it is now time to place a great emphasis on in-depth research on student understanding of technological concepts and processes and ways in which these can be enhanced. 相似文献

With increasing outsourcing and the growing importance of product innovation as a means for creating competitive advantage, the integration of purchasing and product development processes has become a key issue for many firms. Although, consequently, the integration of purchasing and suppliers in product development has attracted growing attention from practitioners and researchers, most research on the topic remains limited to the context of single development projects. The integration with long-term issues such as technological alignment between supplier and manufacturer is often neglected. This limited conception and the lack of a coherent definition of what purchasing integration in product involvement is form a major impediment to the advancement of knowledge in this field. Therefore, this article develops a framework encompassing various activities across different management levels, which embody the alignment and integration of purchasing and product development processes. 相似文献

Research on the CRM-performance link has been fragmented due to various perspectives on CRM. This study, considering different concepts of CRM, proposes a process-oriented framework for examining the relationship among CRM resources, CRM process capabilities, and organizational performance. Based on the resource-based view (RBV) of the firm, CRM resources are classified as “technological CRM resources” and “infrastructural CRM resources”. Data from 77 Iranian Internet service provider firms were gathered in a field survey. The empirical work indicates that the measured constructs demonstrate key psychometric properties including reliability and validity. The results reveal that CRM processes are more affected by infrastructural CRM resources rather than technological CRM resources. Moreover, the findings indicate that firms with improved CRM process capabilities enjoy better organizational performance. 相似文献

A firm's technological knowledge base is the foundation on which internal product and process innovations are generated. However, technological knowledge is not accumulated solely through internal learning processes. Increasingly, firms are turning to external sources in the technology supply chain to acquire the technological knowledge they need to introduce product and process innovations. Thus, the successful structuring and executing of partnerships with external “technology source” organizations is often critical to competitive success in technologically dynamic environments. This study uses situated learning theory as a basis for explaining how factors inherent to the knowledge acquisition context may affect the successful transference of technological knowledge from universities to their industry partners. Data collected via a survey instrument from 104 industry managers were used to explore the effects of various organizational knowledge interface factors on knowledge acquisition success in university–industry alliances. The organizational knowledge interface factors hypothesized to affect knowledge acquisition success in the current research include partner trust, partner familiarity, technology familiarity, alliance experience, formal collaboration teams, and technology experts' communications. Results indicate that partner trust predicts the successful acquisition of tacit knowledge but not explicit knowledge. Both forms of knowledge are predicted by partner familiarity and communications between the partners' technology experts. These findings suggest three principal managerial implications. First, although the development of a trusting relationship between the knowledge source and knowledge‐seeking parties is generally advisable, firms that seek to acquire explicit technological knowledge from their alliance partners may successfully do so without having made significant time and energy investments designed to assure themselves that they can trust those partners. The relative observability and verifiability of explicit knowledge relative to tacit knowledge may enable knowledge‐seeking parties to have greater confidence that knowledge has been acquired when partner trust is in question or has not been deliberately developed. A second implication is that, other things being equal, a knowledge‐seeking party's interests may be best served through repeated exposures to particular alliance partners, particularly if those exposures facilitate mutual understandings on relevant process‐related matters. A third managerial implication is that ongoing, broad‐based communications between the partners' technology experts should be used to effect technology transfer. A key quality of the organizational knowledge interface that promotes the successful acquisition of technological knowledge, both tacit and explicit, is multipoint, real‐time contact between the technology experts of the partner organizations. Such communications potentially enable the knowledge‐seeking party to directly access desired information through the most knowledgeable individuals on an as‐needed basis. 相似文献

Technological change is a major factor in gaining competitive advantage in manufacturing industries. Promoting innovation, exploiting technological opportunities and avoiding threats are increasingly important. Firms need to recognise both current and potential future technological advances that can affect their products, services and processes. This paper presents a Technology Intelligence (TI) methodology and toolset, the main purpose of which is to enable companies to monitor and assess technological developments associated with their products, components, processes and other areas of concern. These technology management activities will assist the company in evaluating its environment while taking advantage of technological changes that represent opportunities or threats. The methodology is described in detail and demonstrated using a case study conducted in an aerospace manufacturing firm in the United Kingdom. 相似文献

The gatekeeper approach to the management of scientific and technical information (STI) is most relevant to companies engaged in product development in a dynamic technological environment (Allen, Tushman, & Lee, 1977). We will argue in this paper that these companies have a choice of how to effectively organize. The organizational structure and processes they implement will have major effects on how STI is transferred as well as the quality of the STI that is disseminated and used. Hence, changing the context within which STI is transferred may be much more effective than improving the efficiency of existing transfer procedures. 相似文献
