Productivity in agriculture and fisheries, for example, depends on annual floodplain inundation and nutrient dispersal. The immense scale and impact of this natural cycle is well illustrated in the annual flooding of Tonle Sap Lake in Cambodia and the Mekong River Delta which it shares with Vietnam.

  • Vietnam is embarking on a path towards a knowledge-based economy in which the emergence of knowledge clusters in Ho Chi Minh City and the Mekong Delta are playing a decisive role. As our paper suggests, clustering appears to have a positive effect not only on the increase of knowledge output, but also on the economic growth of these regions. Using a GIS-based mapping method, we can identify two major knowledge clusters – Ho Chi Minh City and Can Tho City.

  • With globalisation and knowledge-based production, firms may cooperate on a global scale, outsource parts of their administrative or productive units and negate location altogether. The extremely low transaction costs of data, information and knowledge seem to invalidate the theory of agglomeration and the spatial clustering of firms, going back to the classical work by Alfred Weber (1868-1958) and Alfred Marshall (1842-1924), who emphasized the microeconomic benefits of industrial collocation.
