摘　　要：[目的]通过分析蔬菜生产集聚特征及空间相关性,为优化京津冀地区蔬菜生产布局、有效保障蔬菜供给提供参考。[方法]文章利用2011—2016年京津冀13个市、168个县域单元的面板数据,对区域内蔬菜生产变动进行了空间统计与计量分析,揭示京津冀地区蔬菜生产格局的时空分异特征。基于集中度指数、基尼系数分析了京津冀地区蔬菜生产的变动态势、空间集中水平;构建空间权重矩阵,利用莫兰指数和莫兰散点图对京津冀地区蔬菜生产空间相关性进行实证研究。[结果]得到了京津冀地区蔬菜生产的空间分布格局,并对蔬菜生产集中程度和空间相关性进行了检验。[结论]京津冀蔬菜生产水平存在空间负相关性,且相关性呈现减弱趋势。地理相近的市域之间在蔬菜生产上也具有相互依赖性,但依赖程度较低。县域层面上蔬菜生产已经有较高的专业化程度。建议京津冀地区深入推进蔬菜生产区域化和专业化发展。In order to provide a support for optimizing production arrangement and ensuring effective supply for vegetable production in Beijing-Tianjin-Hebei region,the agglomeration characteristics and spatial correlation of vegetable production are analyzed.The 2011-2016 panel data of 13 cities and 168 county units was used to conduct spatial statistics and quantitative analysis of the changes in vegetable production in the Beijing-Tianjin-Hebei region,so as to reveal the characteristics of time and space of vegetable production pattern.Concentration ratio and Gini coefficient were used to analyze the dynamic potential and spatial concentration level of vegetable production in the region.The spatial weight matrix was constructed,and the Moran′I and Moran scatter plots were used to analyze spatial correlation of vegetable production in the Beijing-Tianjin-Hebei region.In summary,there is a spatial negative correlation in the level of vegetable production,and the correlation is gradually weakening.There is also interdependence in vegetable production between geographically similar cities,but the degree of dependence is low.Vegetable production has a higher degree of specialization at county level.Regional and specialized development of vegetable production is recommended in Beijing-Tianjin-Hebei region.
