中国甘薯生产布局变迁及其影响因素研究
THE CHANGES AND INFLUENCING FACTORS OF THE PRODUCTION LAYOUT OF SWEET POTATO IN CHINA
摘要
Abstract
China is a major producer and consumer of sweet potatoes.As an important food crop,cash crop and feed crop in our country,it is of great significance to master the production layout law of sweet potato for ensuring national food security.Based on the panel data of various provinces of sweet potato production in China from 1997 to 2022,the change of sweet potato production center in China was analyzed by using sweet potato planting area,yield,origin concentration coefficient and Moran's I index.The spatial Durbin model was constructed to analyze the specific effects of various factors on sweet potato production layout.The analysis results show that over the past 20-plus years,the center of sweet potato planting and production in China has gradually shifted to the southwest region.The production center is located within Hubei Province,and the spatial agglomeration effect of sweet potato planting has gradually become prominent.At present,the advantageous production areas of sweet potatoes in China are inconsistent with the production capacity agglomeration areas,which restricts the healthy and sustainable development of the sweet potato industry.Therefore,the factors influencing its production layout are studied.Research shows that there is a significant spatial spillover effect in sweet potato production in China.The changes in its production layout are the result of the combined effects of local and neighboring regions'natural conditions,social economy,infrastructure and brand building.Therefore,grasping the change law of sweet potato production layout,improving agricultural production conditions and transportation levels,shaping sweet potato brands with regional characteristics,and strengthening cooperation between different regions to create sweet potato crop advantage producing areas,so as to give full play to its important role in agricultural efficiency,farmers'income increase and industrial poverty alleviation.关键词
