Abstract: Along with the proposed program of urban agglomeration in the middle reach of Yangtze River, the cluster development of the central delta economic zone has become an important engine to enhance the regional economic competitiveness. Based on the location entropy theory, this paper makes an assessment of the resources agglomeration degree of service industry in Hunan-Hubei-Jiangxi area. The results show that this area owns obvious advantages in the natural resources for the service industry, but the economic foundation of this area is weaker, the conditions for the development of the service industry are not good enough, and the reserve of talents is not sufficient. Therefore, in order to give full play to the agglomeration effects of the service industry and promote the sustainable development of the regional economy, it is necessary to integrate the resources of the service industry in those three provinces, program the characteristic industry cluster districts, implement the PPP development mechanism and carry out the construction of the bases for complementary-type talents.
