山东省农业生产效率动态演进及区域差异研究

Study on the Dynamic Evolution and Regional Disparities of Agricultural Production Efficiency in Shandong Province

探究地区农业生产效率的动态演进趋势、分析区域差异对促进区域农业协同发展具有重要意义。文章分别采用超效率SBM模型、核密度估计法与Dagum基尼系数分解法对2008—2022年山东省16个地市农业生产效率的动态演进特征及区域差异来源进行研究。结果表明:研究期内,山东省总体农业生产效率逐年上升,在空间上呈现鲁中>鲁东>鲁西北>鲁西南的空间格局;总体差异呈现波动上升趋势,区域间差异是构成总体差异的主要来源。据此,提出制定差异化的农业发展策略、缩小区域内和区域间差异的优化措施,以期提升山东省总体农业生产效率水平,促进乡村全面振兴。

It is of great significance for promoting coordinated development of regional agriculture to explore the dynamic evolution trend of regional agricultural production efficiency and analyze regional differences.The methods,such as the super efficiency SBM model,kernel density estimation method,and Dagum Gini coefficient decomposition method are used in this paper to study the dynamic evolution characteristics and regional differences of agricultural production efficiency from 2008 to 2022 in 16 cities in Shandong Province.The research results indicate that during the research period,the overall agricultural production efficiency of Shandong Province has been increasing year by year,presenting a spatial pattern of Central Shandong>eastern Shandong>Northwestern Shandong>Southwestern Shandong;The overall difference shows a fluctuating upward trend,and regional differences are the main source of the overall difference.Based on this,it is proposed to formulate differentiated agricultural development strategies and optimize measures to narrow regional and inter regional differences,in order to improve the overall agricultural production efficiency level and promote comprehensive rural revitalization in Shandong Province.
