This abstract has open access
Abstract Summary
Since 1990s, with the deepening of urbanization process, China already entered accelerating development period of urbanization. City-regions, which have been conglomerated by several cities with different functions and sizes, are gradually taking the place of the single city and then deeply influencing the economic growth of China. As a result of the evolution of production systems at different dimensions, highly dense agglomerations of populations, industries, cities, towns and other production factors are gradually gathering together in this large-scale urbanized areas. As a new type of urban spatial structure, City-regions are not only the inevitable outcome of regional and urban economic evolution, but also an organism of division of labor, cooperation and competition. On the one hand,within the reasonable development limit, they are conducive to controlling the blind growth of central cities, avoiding population pressure and excessive concentration of industrial activities brought by excessive expansion of the one cities, at the same time avoiding the uneconomic scale of environmental consumption in smaller-sized cities during their development. On the other, once the spread and development is out of control, problems such as the shortage of energy, water resources and environmental degradation caused by competition for factors of production between neighboring cities, will grow into a full blown crisis. The cities, with more undeveloped resources but at a lower development level (mid-sized city) will become the main victims in this resource garbs. The problem can no longer be solved by a single city, but need planner and local government work in unison to carry out the rational planning and construction of each member city within a larger regional scope. In this context, this paper will focus on the above-mentioned mid-sized city, and how they can grasp the balance of development as much as possible during the process of urban agglomeration evolution? How could they weaken the siphon effect and the excessive loss of resources in the big city-region? What kind of roles do the planner and local government have?In order to discuss with more targeted, Yantai, a mid-sized city in the city-regions of Shandong Peninsula will be taken as an example. This city suffered gains and losses during Shandong regional development, especially on the eco-economic aspect. This paper will give an account of its opportunities and challenges from 1990s to the present, discuss some effective measures taken by local government and planner to stop the drain of its resources and find out some problem still hard to tackle.
