カール・ハウスホーファー
The "Indo-Pacific" has been an economic idea since its early formulation in Weimar Germany. According to Hansong Li, the German geographer Karl Haushofer, son of the economist Max Haushofer, believed that capital, along with urbanisation and population growth, are key vectors that determine the 'manometers' of the oceanic region. Haushofer also explained why industrialisation broke out in Europe rather than the Indo-Pacific by a spatial theory of demography.
