DEVELOPMEMT SITUATION ASSESSMENT AND CLASSIFICATION OF REGIONS ALONG THE YANGTZE RIVER

Regional development is an important theoretical and practical issue in the process of urbanization and industrialization.The assessment of development situation is the premise and basis of further study of regional development.Based on regional sustainable development theory,and the dialectical relationship between regional development level and development costs,we choose the 40 cities which are along the Yangtze River as the basic evaluation unit,select the most important indicators to identify development level and costs,and construct the composite index system based oneconomy-society-resources-environment.We calculate the economic and social development level of the cities,and also the resources and environment costs.According to the two-dimensional matrix,we divide the cities into four zones:zone of high-development level and high-development cost,zone of low-development level but high-development cost,zone of low-development level but high-development cost,and zone of low-development level and low-development cost.From the industrial development,ecological protection,and regional coordination,we propose the corresponding policies and measures for different types of zones,to provide the foundation for a new round development of regions along the Yangtze River.
