Unbalanced Development Characteristics and Driving Mechanisms of Regional Urban Spatial Form: A Case Study of Jiangsu Province, China

Unbalanced regional development is widespread, and the imbalance of in developing countries with rapid urbanization increasingly apparent. This threatens sustainable region. Promoting coordinated region has become a hot spot scientific research major practical need. Taking 99 counties Jiangsu Province China, typical coastal plain region, as basic unit, this paper explores unbalanced characteristics urban spatial form using three indicators: expansion size, intensity, distribution aggregation degree. Then, their driving mechanisms were evaluated autocorrelation analysis, Pearson correlation linear regression, geographically weighted regression. Our results found that areas larger size intensity mainly concentrated southern Jiangsu, where there was positive between them. We no agglomeration phenomenon From perspective factors: economics main factor size; level quality factors intensity. Natural landform are Finally, we discussed optimization strategy development. The integration should be promoted Southern Jiangsu. improved relying on transportation to develop along axis central economic increased, focusing northern study will enrich imbalance, helps optimize regulate from multiple perspectives.
