福建省经济空间增长变异特征及驱动机制

基于区域化变量理论,运用地统计分析方法的空间变异函数,以福建省为本底,从区域经济空间增长的视角入手,分析了自1990年以来福建省经济增长的空间变异特征、空间梯度形态演化过程、分维特征以及空间分布特性。结果表明,在总体空间格局上,空间增长表现出越来越强的自组织性,热点区域从沿海的福州、厦门、泉州向内陆地区转移,总体差异在缩小,空间连续性和结构性越来越强,由空间自相关引起的结构化分异机理越来越显著;从不同方向的空间变异格局来看,经济增长空间分布呈现明显的带状异向性,南北方向上的福州-泉州-厦门沿海一线始终为经济增长的主轴线。最后,解释了经济空间增长格局演化的驱动机制,主要受政策因素、重大基础设施建设等的影响。

Spatial Variability and Evolutionary Mechanism of Economic Growth in Fujian Province

As an important part of economic structure, spatial structure is the distribution pattern and combining form of economic activities in the space. The paper took Fujian Province as an example and analyzed the spatial variability、the pattern evolution of spatial gradient、the fractal dimensions and spatial interpolation of economic growth since 1990s.The results show that: ①Considering the overall spatial variability, economic growth in Fujian Province shows a strong trend of spatial natural correlation. During 1996 to 2002,the hotspot is inclined to aggregate in some core poles.Furthermore,its distribution becomes less uniform, the variation in a small area tends to be reinforced while the overall distribution tends to be more complex. During the period of 2002-2008,the hotspot area changes from coastal area centered on Fuzhou, Xiamen and Quanzhou to inland area. Besides,the spatial difference is likely to shrink.It is also argued that spatial continuity and constitutive property of economic growth,as well as the mechanism of structural difference caused by spatial natural correlation become more and more obvious and remarkable. ② Considering spatial variability in different directions, economic growth takes on a zonal anisotropy by semivariogram functions figures. North-south direction including Fuzhou-Quanzhou-Xiamen is always the main axis of economic growth. ③ Finally, the article explains the driving forces on spatial changes of the diverse economy in Fujian Province and it is found that policy and construction of infrastructure are probably the main reasons.
