Abstract

The paper introduces a dynamic, flexible partial-adjustment model and uses it to analyze the diffusion of Internet connectivity. It specifies and estimates desired levels of Internet diffusion and the speed at which countries achieve the target levels. The target levels and speed of adjustment are both country and time specific. Factors affecting Internet diffusion across countries are identified, and, using nonlinear least squares, the Gompertz growth model is generalized and estimated using data on Internet users for 59 countries observed over the years 1995 to 2002. The empirical results show that infrastructure variables such as personal computer ownership and telephone service increase the equilibrium level of internet diffusion. The speed of adjustment toward a target level decreases over time. Regarding model performance, the generalized dynamic Gompertz model that accounts for unobserved country heterogeneity effects outperforms other, simpler and static model specifications.

Abstract

Industrial transformation is a research and teaching field with a focus on the phenomenon and mechanisms of industrial development and renewal. It concerns changes in economic activities caused by innovation, competition and collaboration, and has a rich heritage of evolutionary economics, institutional economics, industrial dynamics, technology history and innovation studies. It borrows concepts and models from the social sciences (sociology, history, political sciences, business/management, economics, behavioural sciences) and also from technology and engineering studies.
In this book, the authors present the key theories, frameworks and concepts of industrial transformation and use empirical cases to describe and explain the causes, processes and outcomes of transformation in the context of digitalization and sustainability. They stress that industrial transformation consists both of Darwinian “survival of the fittest” selection, and of intentional pursuits of innovation, and of industrial capabilities creation. The work argues that managing the global trends of transformation is not only about new technology and innovation: existing institutional settings and dynamic interactions between technological change, organizational adaptation and economic activities also have a profound impact on future trajectories.
The areas under investigation are of great relevance for strategic management decisions and industrial and technology policies, and understanding the mechanisms underlying transformation and sustainable growth.

Abstract

Open innovation has rendered increased interest both in practice and research, and has expanded from dyadic transfers of ideas, to ecosystem levels. Knowledge is at the heart of open innovation, and this paper describes and discusses knowledge-transfer linkages for open innovation. It does so based on a literature review. The paper links together open innovation research with general management research to categorise and discuss linkages among parties in terms of their openness and how they relate to knowledge management. Conclusions indicate that openness needs to be considered in different dimensions that also links to different knowledge management outcomes. The paper’s contribution consists of how it connects open innovation research to the general management literature, and how it builds a practical understanding of how linkages between firms can be categorised to aid firms to consider which mechanisms they may choose and why.

Abstract

What is the role of innovation policy for accomplishing renewal of mature industries in Western economies? Drawing upon an unusually rich dataset spanning 9752 digitized archival documents, we categorize and code decisions taken by policymakers on several levels while also mapping and quantifying the strategic activities of both entrant firms and incumbent monopolists over a decade. Our data concerns two empirical cases from Sweden during the time period 1980–1990: the financial sector and the telecommunications sector. In both industries, a combination of technological and institutional upheaval came into motion during this time period which in turn fueled the revitalization of the Swedish economy in the subsequent decades. Our findings show that Swedish policymakers in both cases consistently acted in order to promote the emergence of more competition and de novo entrant firms at the expense of established monopolies. The paper quantifies and documents this process while also highlighting several enabling conditions. In conclusion, the results indicate that successful innovation policy in mature economies is largely a matter of strategically dealing with resourceful vested interest groups, alignment of expectations, and removing resistance to industrial renewal.
