Analysis of socio-economic driving forces on built-up area expansion in Xiamen

Based on grey relational analysis and stepwise regression, this study analysed the socio-economic driving forces of Xiamen since the reform and opening of China. The research aimed to explore the deep dynamic mechanism of urban space expansion of Xiamen and provide scientific support for its sustainable development. The results indicate resource consumption factors and population factors have had a significant driving effect on the expansion of built-up area, and have contributed more than the economic development factors. It was revealed that the main urban socio-economic driving forces have gradually changed during the middle and late stage of urbanisation, and the city has also shifted from an original construction and developing city type into a more spatially stable, developed city type.
