Supercluster .. the global meaning when comparing with Thailand's meaning. At the beginning with Silicon Valley as the first-ever supercluster for high-tech industry and relevant association in the 20th century, its learning curve has philosophically provided everyone that we are moving from the world in which the big eat the small to one in which the fast eat the slow. However, while learning from Japan's supercluster, it have been discovered that Japanese people are very keen in what they are and what they would do to enhance their competitive advantage of the nation in the 21st century, particularly with a new concept of the better, the faster. Many environmental friendly projects, such as e-car initiative, have been established and super-clustered their capable networks together for the best efficiency. The aim is to think and do green by launching only better eco-products/eco-services to the global market while promoting slow movement and slow value in the territory. Are those Thailand's competitiveness ? If not, can we follow what we are instead ? Tailor-Made Supercluster would be the best solution. A challenge of establishing a tailor-made supercluster that is acceptable to all stakeholders in the involving areas is to balance the demands of all stakeholders with eco-conscious and socio-conscious responsibilities. By understanding "Four Knowledges of Sustainable Management" would assist these stakeholders to achieve that kind of balance in practice, precisely through the mutual knowledges of community identity, community heritage, community problem, and community future.
