Many scholars indicates borderless globalization, the age of openness, role increase of local instead of nation as topic of the future. Globalization of world economy bring about free migration beyond capitalist enterprise and convert to the direct competition system of the locals instead of faded meaning of the nation. In this paper, we analyzed the meaning and limitation of the super wide range economy areas that is a strategy to overcome the long-term economic stagnation of Busan. Farther the super wide range economy areas, we assert the necessity of the construction of the super wide range life-culture areas in the time frame of wide range and to achieve this, we considered the diverse strategy. The diverse strategy to construct the super wide range life-culture areas follows. First, to be able to the central role in the East-south area, Busan must develop the close cooperation with other regions and role adjustment, distributive and autonomous model. Second, intensively foster industry fit with the region's characteristics. Third, for formation of industries that can product a higher value-added business, Busan must confirm the creative talent pool. Forth, the continuous and deep concerns about the super wide range life-cultural areas. Fifth, the plan of socio-cultural exchange program persue between Busan and Kyushu by stages. Sixth, Busan need the convergence of diverse opinion from the local resident and the establishment of receptiveness about other culture.
