Spatial Variation and Coupling Research of the Industrial Structure and Land Use Efficiency for Central Region—An Empirical Analysis of Panel Data for 46 Evaluation Units Based on Wanjiang City Belt
基于皖江城市带46个评价单元的面板数据，分析了产业结构类型与工业集聚的空间分异，以及工业集聚与工业用地效率的空间耦合程度，发现东南部耦合度高于西北部，整体呈东高西低趋势。
Based on the panel data of 46 evaluation units for Wanjiang City Belt,methods by means of comprehensive location entropy,industrial location entropy absolute difference,coupling relationship,with the help of GIS space associated with the attribute function,analysis the spatial differentiation of main types of industry structure and industrial agglomeration,spatial coupling degree of industrial agglomeration and industrial land use efficiency.Research shows that: wood furniture industry,agricultural processing industry,textile and garment industry as the main industry in most area type,respectively reaching to 26,25,24,reflect the whole region in the low primary industry types;industrial structure agglomeration degree higher area concentrated in northwestern of Dabie Mountain,remote county,and the urban and towns developed industry industrial agglomeration performance is not outstanding;industrial land use efficiency of numerical regional differences,the higher areas are mainly concentrated along the urban development axis and Hefei capital metropolitan area,type of county regional industrial structure of smaller areas concentrated in raw material oriented,labor oriented;the degree of coupling presenting section structure,the southeast is higher than that of the northwest of Wanjiang City Belt,showing a decreasing trend from east to west,and the whole area is divided into four types coupling region of highly coupled,moderate,mild coupling,no coupling.
