县域农业生产集聚形成的影响因素——以环渤海区域蔬菜生产为例

Influencing factors of the formation of agricultural production agglomeration in counties:Taking vegetable production in the Bohai Rim region as an example

为研究县域农业生产集聚形成的影响因素,采用空间杜宾模型,基于县域视角,运用环渤海区域5省市县域农业生产数据,对该区域农业生产空间集聚形成的影响因素进行分析。结果表明:第一,农业生产空间集聚具有正的空间溢出效应,表现为邻近县域农业生产集聚对本县集聚具有促进作用;第二,农业生产要素投入对本地区集聚具有促进作用,邻近县域农业资本投入对本县具有抑制作用;第三,市场需求、地区经济发展水平和交通条件对农业生产集聚具有显著影响。

In order to investigate the influencing factors of the formation of agricultural production agglomeration between counties,this study adopts the spatial Durbin model,and uses the county agricultural production data obtained from five provinces in the Bohai Rim region to analyze the formation of the agricultural production spatial agglomeration based on the perspective of the county.The results shows that:Firstly,the spatial agglomeration of agricultural production has a positive spatial spillover effect,which is manifested in the promotion of the agglomeration of neighboring counties by the agglomeration of agricultural production at the county level.Secondly,The input of agricultural production factors promotes the agglomeration of the region,and the agricultural capital investment of neighboring counties has a depressing effect on the local county.Finally,market demand,regional economic development level and traffic conditions dispaly significant impact on the agglomeration of agricultural production.
