广西农业区位优势空间分异及形成机制

目的]探索广西农业区位优势空间分异及其形成机制,为广西农业区划与相关政策制定提供参考.方法]采用区位商对广西14个地级市的农业区位优势进行测算,并利用固定效应模型对不同优势层次地区区位商的形成机制进行研究.结果]总体上,广西各地区的农业区位优势横向空间异质性强烈,且不同层次地区的形成机制各异.率先实现农业生产与技术服务规模化是加快现代规模化农业进程的关键点,财政支农力度不足、教育水平不高、农业机械化水平低可能成为制约广西现代化农业规模化发展的瓶颈.建议]应强化总体规划布局,推进产业聚集,提高产业溢出效应;因地制宜,完善交通与基础生产设施;完善农业技术服务体系,突破规模化生产限制;提高财政支农效率,提升农民科技素养,实现广西农业合理布局与良性发展.

Spatial differentiation of Guangxi agricultural location advantages and its formation mechanism

Objective]The aim of this paper was to explore the spatial differentiation and formation mechanism of agri-cultural location advantages in Guangxi, and to provide reference for the development of agriculture regionalization and poli-cy making in Guangxi. Method]Location quotient was used to calculate the agricultural location advantages of 14 prefec-ture level cities in Guangxi. The formation mechanism of location quotient of regions with different advantage levels was studied by fixed effect model. Result]The overall spatial differentiation of agricultural location in Guangxi was severe , and the formation mechanism of regions with different advantage levels was different. Realizing scale development of agricultural production and technical service was the key to accelerate the process of modern large-scale agriculture. Lack of financial support for agriculture, low education level and low level of mechanization of agriculture might become bottlenecks for Guangxi modern agriculture scale development. Suggestion]Following suggestions are proposed to realize the rational allo-cation of agriculture and sound development in Guangxi:strengthening the overall planning and layout , promoting industrial agglomeration and improving industry spillover effect; optimizing traffic and infrastructure based on local conditions; im-proving the agricultural technology service system and breaking through the limitation of large-scale production; promoting the efficiency of financial support for agriculture and improving farmers' scientific knowledge.
