中文摘要:

      京津冀农业协同发展是实现京津冀协同发展的“压舱石”。通过采用修正引力模型和社会网络分析方法实证分析2011—2015年京津冀地区13个地市农业经济联系强度、联系方向、联系范围和联系格局的发展变化，发现:随着京津冀一体化进程的深入，京津冀地区农业经济联系强度有所提高；除石家庄外，各城市的农业经济联系方向均未发生变化。在农业经济联系范围和格局上，整个京津冀地区农业经济联系网络密度和网络结构的一般化程度均呈现出上升的趋势，各城市农业经济的集聚能力和辐射能力均有所增强。2011—2015年京津冀地区均形成了由西南向东北层次鲜明的四大板块，同时也均存在着以石家庄、邯郸和邢台为核心城市的核心—半边缘—边缘结构。构建京津冀地区农业经济网络合作机制，充分发挥农业经济核心城市的带动作用和强化北京与京津冀地区其他城市之间的联系，是实现京津冀农业协同发展的重要举措。

英文摘要:

      The coordinated agriculture development of Beijing-Tianjin-Hebei area is a ballast stone for the coordinated development of Beijing-Tianjin-Hebei area. In this paper, using the modified gravity model, the social network analysis method and the Beijing-Tianjin-Hebei area's 13 cities data, makes the empirical analysis of 13 cities changes of the agricultural economic contact intensity, the direction, the scope of contact and the pattern of contact from 2011 to 2015. The results indicate that with the deepening of the integration process of Beijing-Tianjin-Hebei area, the agricultural economic relation intensity has improved and the agricultural economic relation direction has not changed besides Shijiazhuang. When it comes to the agricultural economic ties and pattern, the Beijing-Tianjin-Hebei area agricultural economic contact network density and network structure of general degree shows an upward trend and the agglomeration and radiation capability of the city agricultural economy is enhanced. The Beijing-Tianjin- Hebei area are formed four plates from the southwest to the northeast with distinct levels, and it also exist the core, semi-periphery and peripheral structure taking Shijiazhuang, Handan and Xingtai as the core from 2011 to 2015. Construction of agricultural economic network cooperation mechanism in Beijing- Tianjin-Hebei area, give full play to the leading role of the agricultural economic core city and strengthen ties between Beijing and other cities in Beijing-Tianjin-Hebei area can achieve the collaborative agricultural development of Beijing-Tianjin-Hebei area.
