新疆种植业地理集聚的时空特征与影响因素

Geographic Agglomeration of Planting Industry in Xinjiang: Spatial-temporal Characteristics and Affecting Factors

基于1989—2014年新疆维吾尔自治区14个地州种植业及8类作物的产量数据,运用重心移动模型、区位基尼系数、产业集中率,对新疆种植业地理集聚的时空特征进行分析。整体而言,新疆种植业具有显著的地理集聚特征,呈现出不断增强的趋势,具有明显的拐点和阶段性特征,种植业整体重心呈现出向北偏东的移动趋势,不同作物地理集聚具有显著差异。一些农作物的生产高度集聚在少数地州,地区垄断性不断增强。影响新疆种植业地理集聚的因素日趋多元化和复杂化,主要包括资源禀赋、技术环境、产业环境和制度环境等因素。

Based on yield data of planting industry and 8 crops in 14 prefectures of Xinjiang Uygur Autonomous Region from 1989 to 2014, this paper uses the center of gravity move method, location GINI coefficient, industrial concentration ratio to comprehensively analyses spatial-temporal characteristics of Xinjiang planting industry. On the whole, Xinjiang planting industry has significant geographical clustering feature, and shows a growing trend, and has a clear turning point and stage characteristics. Its center of gravity shows a tendency to move north easterly. Agglomeration of different crops has significant differences. Production of some crops are highly monopolized in a few prefectures with increasing trend about regional monopoly. Factors to affect Xinjiang planting industry get more diverse and complex, including resource endowments, technology environment, industry environment, institutional environment and other factors.
