Abstract:

The use of accessibility potential models is widespread in transport geographical studies. In this analysis the connections between the different accessibility models and development conditions are examined. In connection with the use of the models, the problem arises that, due to their complexity, their interpretation may meet some difficulties. In order to solve this problem, a method which is suitable for breaking down the accessibility potentials into factors has been developed. The study analyses the spatial relation between development and accessibility taking as example the EU NUTS3 regions, the factors of the accessibility potential models are presented and the relations between these factors and the components of development are examined. Finally, the population potential in the NUTS3 regions of EU27 is examined according to the nationality of the dominant region influencing it.

Abstract: 

A model of optimal allocation of investment across regions is developed. It is shown that the optimality conditions may lead to increasing inequalities at the spatial level. Introducing an element of endogenous innovation dualistic situation emerges. An empirical analysis, using data for the NUTS-2 regions of the European Union seems to confirm this argument.

Abstract:

Japan’s economy is entering a new phase of economic growth after the so-called “lost 15 years” since 1990. Particularly Tokyo and Aichi prefectures have been drawing attention as engine of new economic growth in Japan. Although the recovery of Japan’s economy has resulted in an increase in the demand for transportation, construction of new roads in region-wide areas has been in a serious situation. It is attributed to a decreasing trend in Japan’s population and aging which will cause Japan’s national budget being reduced in the future. Due to this situation, stricter economic assessment of new roads development in region-wide areas has particularly been required than before. Taking into account these backgrounds, this article aims to present a model integrating the equilibrium concepts of economic and transport network. Moreover this model will be able to be extended into a full spatial equilibrium model. And then setting San-En region in Aichi and Shizuoka prefectures as a study area which consists of many urban and countryside areas, this study also aims to measure the economic impacts of construction of new roads development in this region.
