以福建省各县域（市辖区）为基本研究单位，选取2021年福建省各县域GDP作为表征区域经济发展规模的特征指标，利用标准差椭圆及空间自相关分析方法分析福建省区域经济发展的空间不均衡性，并构建OLS和GWR模型，研究经济、社会和地理因素对区域经济差异的驱动作用。结果表明：（1）各县域经济总量呈现“东高西低”的分布态势，县域经济空间分布呈现明显的“核心-边缘”结构，县域经济差异显著；（2）各县域经济发展差异具有正的空间相关性，呈现空间集聚性，存在高-高聚类、低-低聚类、低-高聚类3种类型的县域显著聚集区；（3）交通通达度、城市建设水平、内需水平、投资活跃度等方面的差异是导致福建省区域经济差异显著的主要驱动力。
With each county (municipal district) of Fujian Province as the basic research unit, the GDP of each county of Fujian Province in 2021 was selected as the characteristic index to characterize the scale of regional economic development. The standard deviation ellipse and spatial autocorrelation analysis method were used to analyze the spatial imbalance of regional economic development in Fujian Province. OLS and GWR models were constructed to study the driving effect of economic, social and geographical factors on regional economic differences. The results are as followings: (1) The total economic volume of each county presents a distribution trend of “high in the east and low in the west”, and the spatial distribution of county economy presents an obvious “core-edge” structure, with significant differences in county economy.(2) The difference of economic development in each county has a positive spatial correlation, showing spatial agglomeration. There are three types of significant county agglomeration areas: high-high clustering, low-low clustering and low-high clustering. (3) Differences in transportation accessibility, urban construction level, domestic demand level and investment activity are the main driving forces leading to significant regional economic differences in Fujian Province.
