Spatial-Temporal Characteristics and Affecting Factors of Vegetable Produce Geographic Agglomeration in China
利用1978-2012年中国数据，计算空间基尼系数等指标，揭示蔬菜生产地理集聚的时空特征，并分析自然资源、市场需求、技术进步和政策等驱动因素，对蔬菜生产政策制定有参考价值。
Great changes have taken place in the spatial pattern of vegetable production in China since the reform and opening up and vegetable production shows the feature of geographical clustering. It is of great significance for vegetable production policy making to understand spatial- temporal characteristics and affecting factors. The spatial Gini coefficient, FLQ, global spatial correlation and local spatial correlation of vegetable production geographic agglomeration were calculated from the data from 1978 to 2012 in China. The article illustrates the spatial-temporal characteristics and analyzes affecting factors. The research shows that the vegetable production geographic agglomeration present a tendency of increase with stage characteristics. The vegetable production in total showed a medium agglomeration level but the regional agglomeration level varied. Vegetable production geographic agglomeration has the feature of regional gradient and contiguity. The driven force of vegetable production geographic agglomeration mainly include natural resources,market demand, technology progress and policies.
