Clusters are geographic concentrations of interconnected companies, specialized suppliers, service providers, firms in related industries, and associated institutions in a particular field that compete but also cooperate. Inter-connected enterprises co-locate for economic purposes. However, creative cluster differs from other business and industrial clusters. They drive from positive externalities from the diversity of cities themselves (Lorenzen, 2008: Kong,2009). Creative clusters may enjoy opportunities and benefit from positive externalities of diverse economic activities in a city. The spatial concentration of creative industries in urban area refers to the Urbanization economies approach.

From the first critical juncture: Planting the Seeds of creating industry system (2002-2010), SMEs, OTOP Programs, and various public organizations have been set up aimed to promote local culture and local production and tackle the inadequate body of knowledge development respectively. The concept of creative economy promotion policy has been implementing for the last two decades. Several policies and following projects related to creative cities have been rising during the last five years. However, it did not inspire a far-reaching or radical change in urban planning. It is just a buzzword indicating policy-makers intention to be seen to catch up with global trends.

The results of the study indicate that creative industries tend to agglomerate in city-fringe and subsector areas. Creative goods have more clusters in the West part of Bangkok on radius road. Creative services have more clusters in the East part of Bangkok on a ring road. Expressway corridor seems to have more influence on agglomeration rather than public transportation. Three horizontal linkages connect between vertical expressway; Sukhumvit, Ladprawn, and Rama IV Street. Comparing the BTS Sukhumvit line and the Mochit line, the Sukhumvit line tends to have more level of clustering.

The notion of creative clusters arises among policymakers. It has been tied up with strategies of culture-led urban regeneration (Flew,2010).
City brand making and the redevelopment of inner areas associate with cultural infrastructure developments. Thus, the location pattern in Bangkok contrasts with the idea of focusing on inner area regeneration. The neglect of suburban development may support the image of homogeneous development (boring suburban).

These could refer to the cost of creative workers living, including the cost of time spent traveling, as well as the creative infrastructure accessibility. These factors show that Urbanization economies are still very limited. Therefore, even though the image of the various districts in Bangkok is modern as other global cities. But Bangkok still has many challenges in the preparation of the creative ecosystem.
