摘　　要：【目的】认识中国种植业地理集聚的时空特征、演进趋势和集聚效应。【方法】综合利用区位基尼系数、产业集中率、地区平均集聚率、空间相关系数等指标测算中国种植业地理集聚水平,并用引入地理集聚度的C-D生产函数模型分析中国种植业产业的集聚效应。【结果】种植业总体上具有显著的地理集聚特征,但不同行业的地理集聚存在显著差异;中国种植业地理集聚呈现不断增强趋势,并具有明显的阶段性特征;种植业呈现出专业化、连片化的地理集聚特征;种植业产业地理集聚对产业成长具有显著的正效应。【结论】着力提高和完善基础设施建设、搞好区域性的管理和服务,为产业集聚发展创造良好的外部环境;根据比较优势推进具有地区特色的专业化产业区。[ Objective ] This paper is to acquaint the spatial-temporal features, the developing trend of geographic agglomeration and its effects of crop farming. [ Method ] The degree of geographic agglomeration of crop farming was analyzed by comprehensive application of regional Gini index, industry agglomeration rate, regional average agglomeration rate and space correlation index. The agglomeration effects were analyzed by introducing the degree of agglomeration into the C-D production function model. [Result] It is found that crop farming generally has significant geographic agglomeration features which differ a lot among different industries. Geographic agglomeration of crop farming tends to be enhanced continuously, which has obvious stage characteristics. The geographic agglomeration features of crop farming are more and more specialized and flaked. The geographic agglomeration of crop farming has a significant positive effect on the industry growth. [ Conclusion ] China should strive to enhance and improve building infrastructure, ameliorate regional management and services, create a favorable external environment for the development of agriculture agglomeration; promoting agricultural specialization and regionalization process should be based on comparative advantages.
