Decomposition of Factors Affecting Yield Increase in Shanxi Province Sunflower Industry Based on LMDI Model and Countermeasures Research
摘要
Abstract
In order to promote the high-quality development of the sunflower industry,this paper employed the LMDI model to de-compose the factors influencing sunflower yield increases from both provincial and municipal perspectives from 2010 to 2023,and proposeed corresponding policy recommendations.At the provincial level,sunflower yield increases were primarily driven by improve-ments in yield per unit area.Among the 11 prefecture-level cities,five major sunflower-producing regions achieved yield increases:Datong,Shuozhou,Changzhi,Jincheng,and Yuncheng.Regions with notable yield growth trends were concentrated in northern Da-tong and southern Yuncheng,which have maintained a"13 consecutive years of increase"trend.From a regional perspective,the spatial distribution of sunflower production in Shanxi Province in 2023 gradually formed a"northern edible sunflower,southern oil sunflower"spatial layout,with a clear trend toward regional concentration.Among the 11 prefecture-level cities,two regions were dominated by yield effects:Datong and Changzhi,with yield contribution rates of 62.2％and 61％,respectively.The remaining re-gions were dominated by area effects,with Yuncheng,Jincheng,and Shuozhou being the regions where area expansion effects domi-nate,with area contribution rates of 97.6％,64.5％,and 62.9％,respectively.Meanwhile,the regions where area support effects dom-inate were concentrated in the central sunflower planting areas of Shanxi Province,as well as Xinzhou and Linfen,showing a fluctuat-ing trend of decreasing production year by year.In conclusion,the stability of oilseed production area,using sunflowers as an exam-ple,plays an indispensable role in industrial development and capacity enhancement.However,under the current constraints of tight-ening arable land resources and limited room for expansion in planting area,improving yield per unit area and promoting adaptive ad-justments in sunflower industry layout have become key directions for addressing resource challenges and tapping production potential.关键词
