海南省各市县城镇化时空演进特征的主导因素与协调程度研究

Study on the Dominant Factors and Coordination Degree of Spatio-temporal Evolution Characteristics of Cities and Counties in Hainan Province

剖析城镇化内部结构,衡量人口、土地、产业子系统之间的相互作用关系,能够深入理解城镇化发展历程与时空演化过程。文章系统分析海南省"人口—土地—产业"城镇化的时空演变特征、城镇化发展主导子系统、各子系统的静态和动态协调能力,以及不同时间各要素在各地理单元的离散程度,归纳海南城镇化发展的主要特点并进行初步解释。研究发现:(1)海南省屡次承接国家和区域政策、重大项目工程,城镇化发展的"突变性"特点显著,但外部刺激对自身产业结构调整、人口非农就业水平发展未能形成有效的促进作用;(2)海南省各市县正经历"极化—扩散"的过程,海口、三亚"南北两极"特征显著,各市县城镇化发展水平、发展速度、子系统协调程度的差异性逐步缩小;(3)旅游业和房地产迅速发展,土地城镇化成为海南省城镇化发展的主要模式,人口与土地、产业与土地的协调度不足。以期在中国特色自由贸易港建设背景下,对未来协调省域城镇发展与提高城镇化质量提供借鉴。

By analyzing the internal structure of urbanization and measuring the interaction among population,land and industrial subsystems,the development process of urbanization and the spatio-temporal evolution process can be understood.This study systematically analyzes the spatio-temporal evolution characteristics of’population-land-industry’urbanization in Hainan Province,the leading subsystem of urbanization development,the static and dynamic coordination ability of each subsystem,and the dispersion degree of each element in each geographical unit at different times.Then it summarizes the main characteristics of urbanization development in Hainan and made a preliminary explanation.The findings are as follows:(1)Hainan Province has repeatedly undertaken national and regional policies and major projects,and its urbanization development is characterized by"abrupt changes".However,external stimulus has not effectively promoted the adjustment of its industrial structure and the development of non-agricultural employment.(2)Cities and counties in Hainan province are undergoing the process of’polarization-diffusion’.Haikou and Sanya are characterized by’polarization’,and the differences in urbanization level and structure of cities and counties are gradually narrowing.(3)With the rapid development of tourism and real estate,land urbanization has become the main mode of urbanization development in Hainan Province,the coordination degree between-population-and-land and between-industry-and-land lags behind.In the context of the construction of the free trade port with Chinese features(Hainan FTP),this study expects to provide reference for coordinating provincial towns’development and improving the quality of urbanization in the future.
