The paper investigates empirically the decision of firms to adopt ‘Advanced Manufacturing Technologies’ (AMT) based on a comprehensive specification of a ‘rank model’ of technology adoption using firm-level data for Swiss manufacturing. The explanatory variables include numerous dimensions of (anticipated) benefits from and costs of technology adoption allowing for uncertainty as well as for information and adjustment costs. Moreover, the effect of complementarities between various functional groups of AMT (design, fabrication, communication, etc.) as well as of learning from the use of previous technology vintages within such functional groups is analyzed, Finally, the size-dependence of the adoption decision is studied in detail. The model yields a quite robust pattern of explanation across estimates with different adoption variables (time period of introduction of AMT, intensity of use of AMT, etc.) with plausible differences of the results based on the alternative adoption measures used. 相似文献

East Asian development experience provides the basis for understanding which are the essential elements of effective technology strategy and policy, those that are required for the efficacious development of countries that have not yet embarked on a path of sustained modernization. Globalization has had a profound impact on development, enabling countries that could exploit its propelling forces to pursue a potent strategy of export-led economic and technological development. The policies needed to sustain this strategy are those required to foster institutions that permit effective commerce among economic agents, those necessary to generate the rapid accumulation of human and physical capital, and those essential to ensure that resources are allocated in accord with the economy's dynamic comparative advantage. Of crucial importance among the latter are effectively implemented policies of selective intervention designed to develop infant industries and to foster their fast-paced achievement of international competitiveness through rapid attainment of the requisite technological capabilities. 相似文献

The purpose of this study is to investigate the moderating effect and the interactive effect of job scope, role ambiguity and participation in decision-making on relationships between career plateauing and outcomes. A cross-sectional survey of 3,065 Canadian managers shows that these job characteristics can contribute to limiting the negative consequences associated with career plateauing. Moreover, in accordance with the theory of work–situation fit, some double moderating effects are found. The attitudes and behaviours of plateaued managers are significantly more positive when their job is richer and offers an opportunity to participate in decision-making. However, contrary to evidence in the literature, results show that reactions to career plateauing are more positive for managers who perceive that their job is richer and their role more ambiguous. Implications and directions for future research are discussed. 相似文献

运用SPSS软件,对我国高技术产业在技术研发阶段和技术成果转化阶段的技术创新能力进行了实证研究。结果发现,两阶段高技术产业创新能力高低趋势基本一致。其中,通信设备制造业在两阶段技术创新能力均最高,而办公设备制造业、雷达及配套设备制造业、航天器制造业在两阶段的技术创新能力均最低。提高高技术产业技术创新能力,在技术研发阶段应加大创新投入,提高产业创新产出,从而保证技术成果转化阶段研发成果供给。另外,还应加强技术成果转化阶段的经费投入和创新环境建设。 相似文献

The projection on Chinese increasing end-of-life vehicle (ELV) volumes indicates that the volume in 2020 will be about threefold that in 2015. The issue of scrapping vehicle upsurge relative to capacity crunches and environmental impacts perplexes Chinese dismantlers and it is intractable and urgent to choose an appropriate dismantling mode. The purpose of this study is to prioritise four potential dismantling modes and provide decision-making reference for dismantlers with a view to such criteria as environmentally sustainable considering constraints involving economy, technique, ecology and flexibility over changing condition. The conducted evaluation by the analytical hierarchy process (AHP) methodology takes sensitive and problematic aspects into account through questionnaires. The whole evaluation process supported by expert preferences, provides a simple and intuitive knowledge to construct arguments for ELV decision-making process. Results show that disassembly line involves the highest global weight of 0.363 and is concluded to be the best compromised ecological alternative. 相似文献
