国有粮食企业购销的空间协同研究

Spatial Synergy Research on Grain's Purchase and Sale in State-owned Food Enterprises

本文借鉴协同学关于系统协同度的计算方法,界定了空间系统协同度的概念。运用三维灰色关联分析方法,结合2005—2011年三维时空数据,分析了中国各地区国有粮食企业粮食购销的空间协同度,并与系统协同度计算结果进行了比较。结果表明,中国各地区国有粮食企业购销的空间协同度差异较大,主产区国有粮食企业购销空间协同度较高;基于三维灰色关联方法和基于协同学方法计算的空间协同度结果基本一致。最后,提出的具体建议包括充分发挥国有粮食企业的粮食收购潜力,增强主产区国有粮食企业的销售能力等。

Drawing on the calculation method of system coordination degree of synergetics, this paper defines the concept of the spatial system synergy degree. The spatial system synergy degree of grain＇ s purchase and sale in state-owned food enterprises is analyzed with the three dimensional gray correlation analysis method, with three dimensional spatio- temporal data from 2005 to 2011, and is compared with the system synergy degree. Results show large spatial synergy degree differences in state-owned food enterprises, and higher synergy degree of state-owned grain enterprises in major grain-producing area;the results of the spatial system synergy degree are basically identical based on the three dimensional gray correlation analysis method and synergetic degree. Finally, this paper puts forward some specific recommendations, such as giving full play to the potential of grain purchase of state-owned grain enterprises, and enhancing the sales capacity of state-owned grain enterprise in major grain-producing area.
