闽南金三角地区已成为中国东南沿海重要的经济增长高地。然而,在同城化背景下,该地区的城市空间重组、区域协调等问题凸显,严重制约了区域可持续发展。本文运用重心模型揭示了2000-2012年闽南金三角经济增长以及三次产业重心迁移的时空演变特征与规律,并用Nich指数进一步分析三次产业差异。结果表明:(1)闽南金三角地区极化发展现象突出,2000年以来地区经济增长重心与二、三产业重心高度集聚于厦门市东北部,且东西向极化现象较明显;(2)厦、泉两地经济增长博弈激烈,2008年后第三产业开始回迁,且其对经济增长有一定的牵引效应,地区间第二产业非均衡性发展有所收敛;(3)第一产业重心往西南地区迁移的直线型态势显著,漳州市二、三产业发展均滞后于厦、泉地区。
With the rapid regional integration and phenomenal development, the South Fujian Golden Delta(SFGD) has become one of the important growth poles in Southeast China. However, some problems, such as urban spatial reorganization and regional coordination, emerge with the accelerating urbanization and integration. Extensive studies on SFGD focus on qualitative description of the developmental dynamics and industrial strategies, which is inadequate to explain the characteristics of the uneven development within this region. Especially,it is unable to reveal the evolution of the spatial and temporal dimensions of the regional development. In order to analyze the effects of different industries to SFGD and its uneven spatial pattern, the Nich value of different industries and the method of gravity center model are introduced to explore the temporal and spatial characteristics and the dynamic evolvement of the gravity center of economic growth and the tertiary industry in SFGD, in the years between 2000 and 2012. The results show that: Firstly, there is a significant polarization in SFGD. The gravity centers of economic growth, the secondary and the tertiary industries were concentrating on the northeastern Xiamen since 2000, and the trend of a East-West polarization was obvious; secondly, the relationship and interaction between Xiamen and Quanzhou was intensive while the tertiary industry had a leading effect on the center of economic growth, and the tertiary industry moved back since 2008 while the uneven development of the secondary industry was weakened; thirdly, with the linear movement trend of the gravity center of the primary industry towards the southwestern region of SFGD, the growth of the secondary and the tertiary industries of Zhangzhou fell behind, compared with the coast area of the northeast SFGD.
