Abstract This paper focuses on the export performance of US environmental technology (EnviroTech) firms, which are predominantly small and medium enterprises (SMEs). We conceptualize and empirically test a model of perceived export performance contingent upon the perceived effectiveness of host country partner (HCP) alliances, dependence, and trust in the HCP. We find that US SME EnviroTech firms contemplating exports need two critical ingredients for success. First, they must forge close, cooperative, long-term strategic alliances with HCPs for mutual benefit. And second, they must pay specific attention to building trust in the HCP in order to achieve greater success with the strategic alliance and exports. Though dependence on a host country partner increases the vulnerability of the exporter and detracts from an effective alliance, trust is the antidote that can neutralize the negative impact of dependence. 相似文献

Abstract This paper focuses on technology as a central force in shaping cultural and environmental conditions as well as their interrelationships within an organisation. The research was carried out in Systems India Ltd., a subsidiary of Systems Corporation of USA, which is one of the oldest multinational corporations in the world. The two case studies from Systems India Ltd. bring out the ‘role of strategy in technological changes’ and the ‘role of leadership in technological changes.’ The findings of these two case studies when compared with three partner companies in similar industry indicated similar relationship between culture and technological change and organisational culture in Systems India Ltd. 相似文献

The study examines the extent to which disaggregated training variables are related to technological upgrading, in the context of a middle-income developing country trying to manage its integration into the global economy. For a developing country, successful integration into the global economy requires that local manufacturing firms are able to competitively restructure, as a precondition for survival and long-term growth. Consequently, skills and technological upgrading are crucial in raising the international competitive advantage of local firms. Enterprise-provided training is one means that can be used by local firms to continuously upgrade their knowledge bases, increase their international competitiveness, and enhance employment growth over time. This paper uses South Africa as a case study, to demonstrate how economic reform measures can expose skills deficiencies in the manufacturing sector and lead to an increase in capital intensity of the sector. Exposure of skills deficiencies, in turn, raises the importance of skill-upgrading through schooling and training of existing workforce. Despite a couple of studies on the evolution of the labour market in South Africa, no previous research has explicitly examined the relationship between technological upgrading and disaggregated training/learning variables at the firm level. This paper aims to fill that gap by focusing on disaggregated enterprise-based training efforts. The study uses the Human Capital theoretical framework to answer the main research question: Which disaggregated learning variables (i.e., on-the-job or off-the-job training offered to different occupational groups) are significantly associated with technological upgrading? The study raises possible issues of heterogeneity in returns to training offered to different occupational groups in the context of technological-upgrading. On the other hand, technological upgrading may not necessarily always disadvantage all unskilled workers. Possible policy implications of research findings are outlined. 相似文献
