利用ESDA-GIS、空间变异函数、重心迁移与趋势面分析等方法,对2001年和2011年全国343个地级及以上城市GDP含金量的空间分异格局、总体趋势、空间异质性和相关性进行研究。结果表明:中国地级单元GDP含金量空间分异显著,呈现出西部>东部>中部、北方>南方>中部的趋势,具有全局正相关关系。10 a间,GDP含金量的重心向东南方向迁移;黄河以北和长江以南区域的含金量显著减小,而东部沿海和西部沿边地带的含金量显著扩大;GDP含金量的冷点区大幅扩张而热点区大幅收缩。产业结构、居民收入来源、城镇化水平、人力资本存量和初次分配结构是影响GDP含金量的主要因素。
Using the methods of ESDA-GIS, Spatial Variation Function, Center of Gravity Mobility and Trend Surface Analysis, the paper analyzes the spatial distribution pattern, general trend, spatial heterogeneity and correlation of gold content in 343 cities at prefecture level and above in 2001 and 2011 research. The results show that there is a significant spatial difference in the gold content of the prefecture-level units in China, showing a trend of west> east> middle and north> south> middle and has a global positive correlation. During the 10 years, the center of gravity of GDP gold content migrated to the southeast; the gold content in the areas north of the Yellow River and the south of the Yangtze River decreased significantly while the gold content in the eastern coastal areas and the western border areas significantly expanded; Shrink significantly. Industrial structure, sources of income of residents, urbanization level, stock of human capital and primary distribution structure are the main factors affecting the gold content of GDP.
