我国粮食主产区农业高质量发展的区域差异及收敛性分析

全面认识粮食主产区农业高质量发展差异的空间特性,为推动粮食主产区农业高质量的协调发展提供有益启示。本文从新发展理念出发,构建农业高质量发展综合评价指标体系,运用加入时间变量的熵值法测度2003-2018年我国粮食主产区农业高质量发展水平,利用Dagum基尼系数揭示其发展的区域差异大小及其来源,并采用多种收敛方法考察其收敛性特征。结果显示：粮食主产区农业高质量发展水平较低,在波动中呈总体上升趋势;粮食主产区农业高质量发展存在显著的区域差异,其差异在波动中呈总体下降趋势,区域内差异与区域间差异交替成为区域差异的主要来源;粮食主产区农业高质量发展具备典型的收敛和收敛特征,分区域和分时期的收敛性具有明显的异质性特征。因此为提升农业高质量发展水平和缩小区域差距,需要进一步深化农业供给侧结构性改革,积极发展农业新业态和新模式,并通过“追赶效应”和“以高带低”拉动机制,推动粮食主产区农业高质量发展的跨区域协同提升。

The Analysis of Regional Disparities and Convergence of Agricultural High-quality Development in Main Grain Producing Areas in China

A comprehensive understanding of the spatial characteristics of differences in agricultural high-quality development in major grain production areas will provide useful inspiration for promoting the coordinated development of high-quality agriculture in major grain production areas. Starting from the new development concept, this paper constructs a comprehensive evaluation index system for agricultural high-quality development, uses the entropy method with time variables to measure the agricultural high-quality development level of my country''s main grain producing areas from 2003 to 2018, and uses the Dagum Gini coefficient to reveal the regional differences in its development. Size and its source, and use a variety of convergence methods to investigate its convergence characteristics. The results show that: The level of high-quality agricultural development in the main grain producing areas is relatively low, showing an overall upward trend in fluctuations. There are significant regional differences in the high-quality development of agriculture in the main grain producing areas, and their differences show an overall downward trend in fluctuations. Regional differences and inter-regional differences alternately become the main source of regional differences. The high-quality development of agriculture in the main grain producing areas has typicalconvergence andconvergence characteristics, and the convergence by region and period has obvious characteristics of heterogeneity. In order to improve the level of high-quality agricultural development and narrow the regional gap, it is necessary to further deepen the structural reforms on the agricultural supply side, actively develop new agricultural formats and new models, and adopt the "catch-up effect" and "high-band low" pulling mechanism. Promote the cross-regional synergistic improvement of the high-quality agricultural development in the main grain producing areas.
