The island-based"pole-axis system"theory and its utilization in the development strategy of Hainan Free Trade Port
Owing to the long-standing land-sea division,the regional development theory represented by the pole-axis system has conducted insufficient research on the development potential of the land-sea transition zone and even the marine space.In this context,this paper re-explores the marine orientation of the"pole-axis system"theory and investigates the application of the pole-axis system beyond the land-based thinking.Specifically,taking the currently highly-regarded development of the Hainan Free Trade Port(HFTP)as an example,it commences from the general laws of island economies,traces the geographical relationships and development history of Hainan Island,and based on the expansion of the"pole-axis system"theory,deliberates on the development direction and ideas of the HFTP.This paper emphasizes that:(1)The spatial metaphor of isolation and connectivity of islands within the context of the pole-axis system are mutually reinforcing and compatible,and the cultivation and development of the pole-axis system of the HFTP need to take into account the synergetic effects of the island's geographical relationships at different spatial scales,namely the global,national,regional,and local levels.(2)The pole-axis system of HFTP highlights the role of"flow"rather than geographical proximity in the growth of islands and island clusters.The focus on island-island relationships needs to shift from centrality to the exploration of node attributes,while the focus on land-island relationships needs to change from hierarchy to functional complementarity.(3)The HFTP needs to establish an economic and industrial composite pole-axis system that integrates land,island,and sea,and deepen the intrinsic driving force for the coordinated development of different geographic units through the bidirectional interaction of"defining development based on the sea"and"leaning on the land towards the sea".This study hopes to contribute to enriching and enhancing the marine orientation of the"pole-axis system"theory and deepening the study of islands,including the HFTP,other island economies,and the entire island.
