摘要: 基于山东省16个地级市2012—2021年的相关数据,首先构建了农业数字化发展水平指标体系,其次运用熵权法对山东省地级市农业数字化发展水平进行了有效测度,最后通过非参数核密度估计、Moran's I和Dagum基尼系数分析了山东省农业数字化发展水平的动态演进特征、空间集聚特征、区域差异及来源。结果表明,山东省16个地级市农业数字化发展水平不均衡,省会经济圈农业数字化发展水平两极分化问题较严重,胶东经济圈呈多极化态势,鲁南经济圈趋向平均化;山东省农业数字化发展水平整体呈“高-高”组合和“低-高”组合的空间集聚特征;山东省农业数字化发展水平的差异贡献率由大到小依次为经济圈间、超变密度、经济圈内。因此可以采取发展特色农业、因地制宜,完善数字基础、科技助农,延长农业产业链、提高商品化率,加强区域合作、缩小差距等措施提高山东省农业数字化发展水平。

Abstract: Based on relevant data from 16 prefecture-level cities in Shandong Province from 2012 to 2021,firstly, an agricultural digital development level indicator system was constructed,secondly, the entropy weight method was used to effectively measure the agricultural digital development level of prefecture-level cities in Shandong Province,finally, the dynamic evolution characteristics, spatial clustering characteristics, regional differences, and sources of the agricultural digital development level in Shandong Province were analyzed through non parametric kernel density estimation, Moran's I, and Dagum Gini coefficient. The results showed that the agricultural digital development level of 16 prefecture-level cities in Shandong Province was imbalanced, and the polarization problem of the agricultural digital development level in the provincial capital economic circle was more serious. The Jiaodong economic circle showed a multipolar trend, while the Lunan economic circle tended to be average;the overall agricultural digital development level in Shandong Province exhibited spatial agglomeration characteristics of “high-high” combination and “low-high” combination;the differential contribution rate of the agricultural digital development level in Shandong Province was ranked from large to small among economic circles, super variable density, and within the economic circle.Therefore, measures such as developing characteristic agriculture, adapting to local conditions, improving digital infrastructure, technology assistance to agriculture, extending the agricultural industry chain, increasing commercialization rates, strengthening regional cooperation, and narrowing disparities could be taken to improve the agricultural digital development level of Shandong Province.

Key words: agricultural digital development level, the spatiotemporal evolution characteristics, regional differences, non parametric kernel density estimation, Dagum Gini coefficient, Moran's I, Shandong Province
