摘要
为了科学评估农业现代化发展水平,选取中国31个省份2013-2021年的农业现代化相关指标数据,利用熵值法进行分析.基于空间相关分析理论,探索农业现代化水平的空间特征,并建立合适的空间回归模型考查数字经济对农业现代化水平的影响规律.研究发现农业现代化水平呈现明显的地区差异,但整体上逐年稳步上升.同时,农业现代化水平存在显著的空间集聚效应,大多省份与其邻近省份呈现高-高或低-低的空间聚集模式.数字基础设施水平、企业数字化发展水平和数字经济产业发展水平是影响农业现代化发展的主要因素,且均存在着空间溢出效应.为此建议各省发挥自身优势,因地制宜地制定农业发展策略.政府加大资金扶持力度,大力推进基础设施建设,吸纳数字经济型人才,完善数字化转型的软硬件基础,提高数字基础设施和经济产业发展水平.
Abstract
In order to evaluate the development level of the agricultural modernization sci-entifically,the relevant index data of the agricultural modernization in 31 provinces in China during the years from 2013 to 2021 are collected and the entropy method is used.The spa-tial characteristics of the agricultural modernization level are explored by using the spatial correlation analysis theory.A suitable spatial regression model is established to examine the influence of the digital economy on the agricultural modernization level.It can be seen that the development level of the agricultural modernization displays some significant regional variations and increases steadily year by year.At the same time,there is a significant spatial agglomeration effect in the level of agricultural modernization.The spatial agglomeration effect which is characterized by a high-high or low-low spatial association pattern in most provinces and their neighboring provinces can also be found.The level of digital infrastruc-ture,the level of enterprise digital development and the level of digital economy industry development are the main factors that affect the development of the agricultural moderniza-tion,and all have spatial spillover effects.Therefore,it is recommended that each province makes use of its own advantages and formulates the agricultural development strategies tai-lored to local conditions.The government should increase the financial support,promote the infrastructure construction,attract the digital economy talents and improve the software and hardware foundation for the digital transformation to improve the levels of the digital infrastructure and economic industry development.
