Abstract

Regional inequality in the process of economic growth has recently been a popular topic. This paper creatively proposes contribution decomposition methods to divide various regions' contributions into economic contribution and population contribution. The methods consider not only economic growth but also population change, which may be more effective than the traditional method that uses the per capita GDP (gross domestic product) as its single measurement indicator. Moreover, the objective is to take a step forward and reveal the spatio‐temporal evolution characteristics of regional disparities by integrating barycentre model and economic development equilibrium model. Lastly, the applicability of the research method proposed in this paper is verified by a case study of Jiangsu province, China; the results show a new regional economic pattern in Jiangsu province. La desigualdad regional en el proceso de crecimiento económico ha sido recientemente un tema popular. Este artículo propone creativamente métodos de descomposición de contribuciones para separar las contribuciones de varias regiones respecto a la contribución económica y la contribución de la población. Los métodos consideran no sólo el crecimiento económico sino también el cambio de la población, que puede ser más eficaz que el método tradicional que utiliza el PIB (producto interno bruto) per cápita como el único indicador de medición. Además, el objetivo es dar un paso adelante y revelar las características de la evolución espacio‐temporal de las disparidades regionales mediante la integración de un modelo de baricentro y un modelo de equilibrio del desarrollo económico. Por último, la aplicabilidad del método de investigación propuesto en este artículo se verifica mediante un estudio de caso de la provincia de Jiangsu (China); los resultados muestran un nuevo patrón económico regional en la provincia de Jiangsu. 近年、経済成長の過程における地域間不平等がよく話題となっている。本稿では、様々な地域の寄与を経済寄与と人口寄与に分類する分解法を提案する。この方法は、経済成長だけでなく人口の変化も考慮しており、1人当たりGDP(国内総生産)を単一の測定指標とする従来の方法よりも、有効である可能性がある。さらに、重心モデルと経済発展均衡モデルを統合することにより、地域格差の時空間発展特性を明らかにすることを目的とした。最後に、ここで提案した研究方法の適用可能性を中国江蘇省の事例を用いたケーススタディにより検証した。結果から江蘇省における地域の新たな経済パターンがされる。
