南菜北运试点扩大对产销两地间蔬菜市场整合的影响

摘要

通过相关性分析和多元回归模型对南菜北运试点扩大前后产销两地间蔬菜市场整合的变化情况进行了研究。研究结果表明，南菜北运试点扩大对主产区-主销区、主销区-主销区间的市场整合影响方向相反，影响程度不同；南菜北运蔬菜生产基地间的蔬菜供给结构有待改善，蔬菜输送品种间存在部分重叠区间；距离因素在很大程度上阻碍了我国南菜北运市场整合的进程。%Based on correlation analysis and multiple regression model, this paper researched the changes of vegetable market integration after expanding the pilot work of south-to-north vegetable transportation. The results showed that, firstly, the expanding of pilot had a different opposite influence on the main producing areas-sales areas and the main sales areas-sales areas, also had a different degree. Secondly, the supply structure should be improved for the vegetable production bases participating in south-to-north vegetable transportation, and the supply cultivars were partly overlapping. Thirdly, distance hindered the process of vegetable market integration widely.
