Technology transfer is a common method for companies to acquire new technology and presents both challenges and substantial benefits. In some cases especially in developing countries, the mere possession of technology does not guarantee a competitive advantage if the appropriate infrastructure is not in place. In this paper, we identify the localization factors needed to provide a better unders...

This paper analyses the paths of technology development among regions with heterogeneous economic and technological characteristics, focusing on the case of China. It finds that intra-national technology transfer, that is, the technology transfer from technologically advanced provinces to less advanced ones, is more important than that taking place through FDI in the backward regions. In techno...

Prior research highlights the vital role of information technology (IT) for innovation in firms. In this paper, we draw on the knowledge-based view of the firm to investigate how search in external knowledge sources and information technology for knowledge absorption jointly influence process innovation performance. Our model is tested on a nineyear panel (2003–2011) of Swiss firms from a wide ...

This paper investigates “slacking with Internet technologies” in a classroom environment. Rooted in the literature on social loafing, we develop a model linking attributes of the context, the individual, and technology to “intention to cyber-slack” and its influence on the effective use of Internet technology. Using data collected from 128 student respondents, we empirically test our model usin...
