Comparison between"pole-axis system"theory and other related spatial development models
The k=4 system of the central place theory,growth pole and development axis,corridor or axis development,growth pole and growth center,poles and corridors development,and the small-scale development axis are typical development models with spatial significance.In this article,we compare them with the"pole-axis system"theory proposed by Chinese geographer,Lu Dadao,and investigate the similarities and differences in terms of core ideas,attentions and structures.It is shown that these six models have respectively discovered or concerned the various roles of industrial linkages or/and linear infrastructure in spatial economic development,focusing on spatial interaction mechanisms of some roles and also have spatial development propositions.Each of the six models may contribute to the studies on real striped economic system in some ways.However,the"pole-axis system"proposes the gradual diffusion of"pole-axis"and its hierarchical system generation mechanism,and integrates the generation mechanism of the"pole-axis system"with regional resources,environment,and development potential to determine the order of China's spatial development.It is the key feature that distinguishes the"pole-axis system"from the other aforementioned models.
