Analysis on Migration and Driving Forces of Chinese Jujube Production Areas
摘要
Abstract
Jujube(Ziziphus jujuba)originated in China,is an important and unique non-commercial fruit tree species.In the past 20 years,due to the heavy losses caused by fruit cracking during the mature period in the traditional jujube production areas,resulting in the decrease of fruit output and quality.The cultiva-tion center of Chinese jujube began to move from traditional jujube region(distributed around the middle and low reaches of the Yellow River)to northwestern China.With the advancement of the process of"the east-to-west migration of jujube",the Northwestern China,including Shaanxi,Gansu,Ningxia,and Xinjiang has become the main part of jujube industry.The relocation of jujube area brings new opportunities to Chi-nese jujube industry and challenges to the industry of Northwest jujube production area.This article ana-lyzed the changing characteristics of jujube production,planting area,land yield,production concentration,and place of origin concentration in China over the past 20 years.The migration and evolution patterns of Chinese jujube production areas were analyzed by the center of gravity theory model.And the main driving factors of the changes in Chinese jujube production areas was analyzed by panel data.The results showed that the concentration coefficient of jujube production areas in China increased from 2001 to 2021,the coef-ficient was up to 0.66 in 2021.The land productivity,jujube production concentration coefficient,and com-parative advantage of Xinjiang jujube region were significantly higher than eastern traditional jujube area.In the past 20 years,center of gravity of jujube production,cultivation area,and jujube land productivity in China had moved from east to west by 2 257.37,1 629.58 and 264.99 km,respectively.Center of gravity movement trajectory moved to jujube eugenics areas and best eugenics areas in Xinjiang,Shaanxi,Gansu,Ningxia,showing the trend of"the east-to-west migration of jujube".The main factors driving the migra-tion of jujube producing areas included mature rainfall,grain supply level,non-agricultural employment lev-el,and net income of rural residents.This study aims to provide a basis and guidance for optimizing the re-gional layout and planting structure of jujube production areas in China,as well as for the sustainable de-velopment of the industry.关键词
