Accessibility has for many years been a widely used tool in transportation research. Many definitions have been suggested and researchers have constructed numerous mathematical formulations to measure its value in order to be able to evaluate the relationships between the nature of the transport systems and the patterns of land use. Such correlations have been used especially in assessing existing transport systems and forecasting their performance to provide decision-makers with ideas about the need for investments in the transport systems. However, accessibility measures can be regarded as the spatial counterparts of discounting. The measures represent the spatial distribution of economic agents and their activities in a simple way that imposes a very clear structure upon the relationship between these agents and their activities and their environment. Various frictional effects arising from geographical distance between economic agents determine their interaction options, that is, their options to trade, to cooperate, to learn, to commute, and so on. Observing that the time sensitivities of the economic agents vary between different spatial scales (and between different economic activities) we may impose a spatial structure (for example, local, intra-regional, interregional and international) which offers opportunities to define variables in such a way that spatial dependencies can be accommodated. These newly defined variables can then be used in empirical explanations of various spatial phenomena, such as patent output, new firm formation, the emergence of new export products, and economic growth in different spatial units. We will in this chapter against this background show that accessibility is an underused analytical and empirical tool in regional science with an underestimated potential.
Knowledge, Technology and Internationalization
Edited by Charlie Karlsson, Urban Gråsjö and Sofia Wixe
Innovation and entrepreneurship are the prime drivers in the global economy. This scholarly book identifies some of the key forces behind innovation and entrepreneurship at the same time as it closes the gap between science and technology R & D, innovation, entrepreneurship, productivity growth, and internationalization. The expert contributions explore the underlying forces and add substantial theoretical and empirical knowledge to the current state-of-the-art in several research fields including the economics of innovation and entrepreneurship, regional economics, economic geography and international economics.

The main purpose of this Handbook is to provide overviews and assessments of the state-of-the-art regarding research methods, approaches and applications central to economic geography. The chapters are written by distinguished researchers from a variety of scholarly traditions and with a background in different academic disciplines including economics, economic, human and cultural geography, and economic history. The resulting handbook covers a broad spectrum of methodologies and approaches applicable in analyses pertaining to the geography of economic activities and economic outcomes.
Innovations, Networks and Collaborations

Today we can observe an increasing spatial divide as some large urban regions and many more medium-sized and small regions face growing problems such as decreasing labour demand, increasing unemployment and an ageing population. In view of these trends, this book offers a better understanding of the general characteristics and specific drivers of the geographies of growth. It shows how these may vary in different spatial contexts, how hurdles and barriers to growth in different types of regions can be dealt with, how and to what extent resources in different areas can develop, and how the potential of these resources to stimulate growth can be realized.
