| 摘 要： | 【目的】研究广西甘蔗生产规模发展形势及时空关联分布特征，为提升广西区域甘蔗产业的竞争力、推动广西甘蔗产业持续发展提供参考。【方法】利用规模比较优势指数对广西14个地级市的甘蔗生产规模比较优势进行分析，采用空间计量模型研究其时空关联分布特征，并对影响甘蔗规模比较优势的内部因素进行显著性分析。【结果】2011—2018年广西14个地级市的甘蔗规模比较优势指数均大于0，且省域整体甘蔗规模比较优势指数均大于1.10；各地级市间规模比较优势指数又具有显著差异性，呈现一轴两翼的分布局面，其中桂中和桂西较高，最大值为3.50左右；桂东偏低，数值均小于0.10，表明广西区域内甘蔗生产仍存在较大发展空间。从空间均衡性来看，2011—2018年全局Moran’s I指数均大于0.10，表明广西甘蔗生产规模比较优势存在显著为正的全局自相关性，并根据LISA集聚的结果进一步表明，高集聚区数量逐渐增加至4个，无显著相关性区域的数量由9递减至2个，整体呈现出点—带—片的空间结构特征，省域间空间集聚关联性不断增强。通过空间计量模型实证分析得出，影响因素按照显著性程度大小依次为单位面积机械化水平、产业结构指标、财政支农水平、农户人均纯收入，而单位面积劳动力对其不产生显著性影响，具有明显的空间溢出效应。【建议】依据广西各市甘蔗规模比较优势空间格局特征及因素间影响程度进行优劣互补，增强桂中甘蔗“双高”基地空间溢出效应；培养良种，有效降低农户甘蔗生产及企业加工成本，保障甘蔗产业规模化经营，从而实现甘蔗生产综合效益最大化。

| Abstract: | 【Objective】To study the development situation of sugarcane production scale in Guangxi and the characteristics of spatial and temporal correlation distribution, so as to provide reference for improving the competitiveness of Guangxi regional sugarcane industry and promoting the sustainable development of Guangxi sugarcane industry.【Method】The scale comparative advantage index(SAI) was used to analyze the scale comparative advantage of sugarcane production in 14 prefecture-level cities in Guangxi, and the spatial econometric model was used to study its spatial and temporal correlation distribution characteristics and to analyze the significance of internal factors affecting the scale comparative advantage of sugarcane.【Result】The scale comparative advantage index of 14 prefecture-level cities in Guangxi sugarcane production from 2011 to 2018 was greater than 0, among which the overall scale comparative advantage index of sugarcane in the province was above 1.10, which was in an obvious advantageous position;the scale comparative advantage index among prefecture-level cities also had significant differences, showing one axis and two wings pattern. Among them, central Guangxi and western Guangxi were higher, with the maximum value reaching about 3.50;eastern Guangxi was lower, with the value less than 0.10, indicating that there was still more room for development of sugarcane production in Guangxi. In terms of spatial equilibrium, the global Moran's I index from 2011-2018 was greater than 0.10, indicating that there was a significant positive global autocorrelation of the comparative advantage of sugarcane production scale in Guangxi, and further indicated that the number of high clustering areas gradually increased to four, and the number of areas without significant correlation decreased from nine to two according to the results of LISA clustering. The overall spatial structure of point-belt-slice was characterized by increasing inter-provincial spatial agglomeration correlation. Through the spatial econometric model, the influencing factors in order of significance were mechanization level per unit area, industrial structure index, financial support ratio and per capita net income of farming households, while labor force per unit area did not have significant influence on it, which had obvious spatial spillover effect.【Suggestion】Based on the characteristics of spatial pattern of comparative advantages of sugarcane scale in each city of Guangxi and the degree of influence among factors to complement the advantages and disadvantages, enhance the spatial spillover effect of sugarcane double-high base in central Guangxi, breed fine varieties, effectively reduce the production cost of sugarcane for farmers and processing cost for enterprises, guarantee the scale operation of sugarcane industry, so as to maximize the comprehensive benefit of sugarcane production. |
