摘要/Abstract

摘要： 农业机械化发展是保障我国农产品供给、促进农民增产增收、持续巩固脱贫攻坚成果的强有力支撑,研究我国农业机械化综合发展水平地区差异及收敛特征发展有利于识别农业机械化发展不均衡的根本原因,为政策制定者提供数据支持,平衡资源配置,缩小地区发展差距,进而全面推进乡村振兴。根据2004—2021年农业机械化生产有关数据,利用熵值法测算我国农业机械化综合发展水平,测算Dagum基尼系数描述其区域差异;利用空间探索性分析其产业集聚,检验其收敛性。研究表明:2004—2021年期间,我国农业机械化综合发展水平略有上升,由0.319 0上升至0.345 4,涨幅较小。我国农业机械化综合发展空间分布的地区差距有缩小趋势。从整体上看,我国农业机械化综合发展受邻近省份的影响较为明显,基本呈现高值与高值相邻、低值与低值相邻的地理集聚特征,且具有明显的正向相关性特征。农业机械化发展水平较低区域对水平较高区域有“追赶效应”,且相邻城市之间农业机械化综合发展的空间正向关联较强。据此提出,加大资金与相关科研投入、提高政策针对性、深化区域分工与合作等方面建议。

Abstract: The development of agricultural mechanization is a strong support for ensuring the supply of agricultural products in China, promoting the increase of farmers production and income, and continuously consolidating the achievements of poverty alleviation. Studying the regional differences in the comprehensive development level of agricultural mechanization in China and the development of convergence characteristics are conducive to identifying the root causes of the uneven development of agricultural mechanization, providing data support for policy makers, balancing resource allocation, and narrowing the regional development gap, and then comprehensively promoting the rural revitalization. Based on the data related to agricultural mechanization production from 2004 to 2021, the entropy method is used to measure the comprehensive development level of agricultural mechanization in China, and the Dagum Gini coefficient is calculated to describe its regional differences. Spatial exploratory analysis is used to analyze its industrial agglomeration and test its convergence. Research result shows that during 2004 and 2021, the comprehensive development level of agricultural mechanization in China has increased slightly, from 0.319 0 to 0.345 4, with small increase. The regional gap in the spatial distribution of comprehensive agricultural mechanization development in China has a trend of narrowing. On the whole, the comprehensive development of agricultural mechanization in China is more obviously affected by neighboring provinces. It basically shows the geographical agglomeration characteristics of high values adjacent to high values and low values adjacent to low values, and has obvious positive correlation characteristics. Areas with a lower level of agricultural mechanization development have a “catch-up effect” on areas with a higher level, and the spatial positive correlation between adjacent cities in the comprehensive development of agricultural mechanization is strong. Based on this, suggestions are put forward to increase capital investment and related scientific research investment, improve policy pertinence, and deepen regional division of labor and cooperation.

Key words: agricultural mechanization, regional differences, location Gini coefficient, property of convergence
