摘要
笔者通过对1982年-2012年大豆种植重心、基尼系数、空间自相关和区位商的计算，结合全国及各省区大豆产量、单产和种植面积的变动情况，探讨了中国大豆种植的地理集聚格局、演化路径及其机制。结果显示：（1）大豆种植地理分布重心一直处在中国的偏东北方向；从移动方向来看，重心分别在向东北、西南方向周期性徘徊变动。（2）大豆种植空间集聚格局明晰，集聚程度经历了增加、减小、再增加、再减小的周期性变化，专业化种植明显但程度逐渐下降。（3）重心转移轨迹和地理集聚格局演变表现出一致的周期性和阶段性。东北地区大豆种植专业化水平和集聚程度直接决定了全国大豆种植集聚与专业化生产的格局。（4）虽然自然禀赋决定了农作物最初的集聚格局，但开放条件下经济、技术和政策因素对大豆种植集聚格局演变的影响更大。
Based on the calculation of barycenter coordinates, Gini coefficient, spatial autocorrelation and LQ of soybean in 1982 -2012 in China, combined with the soybean output, yields and acreage in the provincial, this paper analyzes the spatial pattern andmechanism of soybean planting agglomeration. It presents that ： （ 1 ） The barycenter of soybean planting was distributed in the northeastof China. Its moving trajectory was along a cyclical change on northeast to southwest. （2） The spatial pattern of soybean planting ag-glomeration was distinct, but the regional specialization degree was gradually weakened, and the degree of agglomeration has experi-enced a periodic change from increase-decrease-increase-decrease. （3） The agglomeration and specialized degree of soybean plantingin Northeast area of China significantly influences on the clustering and specialized production pattern of national soybean planting. （4）Natural endowments determine initial agglomeration pattern of soybean planting, but the economic factors, technological factors and in-stitutional factors will affect more on the agglomeration pattern of soybean planting in Chinese open-up era.
