广西水稻产业规模比较优势及其空间格局特征研究

Scale comparative advantage and spatial characteristics of rice industry in Guangxi

【目的】研究广西各地的水稻规模比较优势指数及其空间特征,为水稻生产与产业规划提供参考。【方法】以广西14个地级市为研究单元,利用规模比较优势指数模型测度其水稻规模比较优势指数,然后采用探索性空间数据分析方法(ESDA)对其空间格局特征进行分析。【结果】整体上,广西平均水稻规模比较优势指数在波动中呈下降趋势;在空间分布上,广西水稻规模比较优势指数大致呈从东南往西北方向递减的特征,并表现出明显的高高聚集和低低聚集特征。【建议】加强政府宏观领导,突出地区农业发展比较优势;强化桂东南地区水稻主导产业,提高空间溢出效益;促进资源优势互补,加快产业空间集聚;加快特色农产品品牌培育,提高产业分工效益。

[Objective]The present study was conducted to study the rice comparative advantage index and its spatial characteristics in each region of Guangxi, and provide reference for rice production and industrial planning. [Method]Taking 14 prefecture-level cities of Guangxi as research units, researchers used scale comparative advantage index model to mea-sure rice scale comparative advantage index and then used exploratory spatial data analysis （ESDA） to analyze the spatial pattern characteristics. [Result]Overall, Guangxi average rice scale comparative advantage index showed a downward trend in fluctuation. In terms of spatial distribution, Guangxi rice scale comparative index decreased from southeast to northwest, and presented high-high aggregation and low-low aggregation. [Suggestion]Following suggestions are proposed：strengthe-ning government macro guidance; utilizing regional agricultural development comparative advantages; developing rice leading industry in southeast of Guangxi and improving space spillover benefits; promoting complementarity of resources and accelerating industrial spatial agglomeration; developing characteristic agricultural products brand and increasing efficiency of industrial division.
