Abstract

type="main" xml:lang="es"> Resumen . En respuesta a las crecientes restricciones ambientales, la mejora de la eficiencia energética para el futuro se ha convertido, a la par que el crecimiento de las economías regionales, en una cuestión política importante para Japón. Este artículo utiliza un modelo de frontera estocástica para estimar la función de demanda de energía y analizar los niveles y los determinantes de la eficiencia energética. El análisis empírico realizado empleó datos de 47 prefecturas de Japón y reveló las cuatro conclusiones siguientes. En primer lugar, se encontró que la medida de la eficiencia energética propuesta (calculada mediante el modelo de frontera estocástica) es eficaz, ya que su posición en la clasificación está altamente correlacionada con la de la intensidad energética. En segundo lugar, el aumento de la densidad de población es eficaz para mejorar la eficiencia energética. En tercer lugar, la mejora de la accesibilidad regional mediante el desarrollo de una red de carreteras ayuda a mejorar la eficiencia energética en Japón. En cuarto lugar, el nivel de eficiencia energética se está deteriorando en las zonas de conglomerados de industrias de materias primas. Estos resultados indican que la manera de aumentar tanto la productividad económica como la eficiencia ambiental es poner en práctica una política de descentralización regional mediante la creación de grandes zonas urbanas en todo el país y extender la red de transporte para vincular estas zonas. Además, la promoción de la innovación tecnológica a través de regulaciones ambientales adecuadas es importante para avanzar en este tipo de políticas regionales.
