Spatial Development Characteristics of Typical Port-Neighboring New Cities in China since the Reform and Opening Up.

Since the reform and opening up, a number of post-neighboring new cities have been built in various regions of China for economic development of coast regions. In order to reflect the overall characteristics of the spatial development of port-neighboring new cities nationwide, 17 typical port-neighboring new cities with a spatial structure of "post-industry-city" were selected as the research object, and the spatial expansion characteristics, the spatial structure characteristics, the main problems, the influencing factors of spatial development were analyzed. The results are shown as follows. 1 The spatial expansion of post-neighboring new cities showed a development pattern of agglomeration-dispersion-agglomeration with time variation. The post-neighboring new cities built in 1980s and 1990s were dominated by marginal expansion and their space was relatively compact. While, those built in the 21st century were mainly based on enclave-style expansion, with rapid spatial expansion but relatively scattered development. 2 The post-neighboring new cities built in 1980s gradually formed a stable spatial structure of "port-industry-city" (20% = 45% = 35%)and the spatial connection with the central urban area was continuously strengthened. For the post-neighboring new cities built in 1990s,the proportion of industrial land increased, and the post-neighboring new cities had a diminished tendency to grow closer to central cities. The post-neighboring new cities built in the 21st century had a relatively high proportion (over 65%) of industrial land and a relatively low proportion of urban land, the spatial correlation between the port-neighboring new city and the central city is very low. 3 The differences in spatial expansion and spatial structure of the post-neighboring new cities were affected by the development of posts, spatial distance with the central urban area, post construction time, population increment, etc. Finally, the suggestions are put forward to the development of the post-neighboring new cities built in different ages.
