Evaluation on Sustainable Development of Urban Agglomeration under the New Urbanization and the Industrial StructureUpgraded Based on a Case Study of Beibu Gulf Urban Agglomeration

The new urbanization has a connotation of human-centered urbanization, covering the synchronization of informatization, industrialization, agricultural modernization and urbanization, the optimization of layout, ecological civilization, cultural inheritance, and the realization of balanced and sustainable development among population, economy, society, resources and environment. Taking the path of new urbanization is the development direction of Chinese cities in the future.It is an important measure taken by the Chinese government to implement the new concept of development to promote the optimization and upgrading of the industrial structure and achieve balanced development between ecological and ecological protection and economic and social development. In this paper, firstly, based on the relevant theories of urbanization at home and abroad, the evaluation index system of urban sustainable development is constructed in five dimensions: economic market driving force, population and social development force, resources and environment carrying capacity, public service guarantee force, and urban-rural integration and aggregation force to study the cities and counties in the Beibu Gulf urban agglomeration region. Then, the factor analysis method is used to perform sub-item and comprehensive evaluation on the urban sustainable development capability. Finally, combined with the development characteristics of each city in the urban agglomeration, relevant development strategies and suggestions are put forward to provide reference for the development of urbanization.
