我国粮食新质生产力水平测度、时空演变及障碍因素分析
Level Measurement,Spatio-temporal Evolution and Obstacle Factors Analysis of New Quality Productive Forces of Grain in China
摘要
Abstract
Cultivating new quality productive forces of grain is an important measure to build a modern agricultural country and lay the foundation for food security.Based on the panel data of 31 provinces in China(excluding Hong Kong,Macao,and Taiwan)from 2013 to 2024,empirical methods such as entropy method,Dagum Gini coefficient,Kernel density estimation,ArcGIS,and obstacle model were used to systematically study the development level,regional differences,spatial and temporal evolution and obstacle factors of China's new quality productive forces of grain.The results showed that:China's new quality productive forces of grain had steadily improved,but the overall level of development was weak and the growth rate was slow;the development level of new quality productive forces of grain in the three major grain-producting functional areas was the main production area>the main sales area>the production and sales balance area,the development level of new quality productive forces of grain in the three major geographical locations was eastern>central>western;the new quality productive forces of grain in China showed a slow and progressive evolution trend in time sequence,and the spatial distribution showed a better evolution trend in the eastern region,while the evolution process in the central and western regions was relatively slow;the intensity of agricultural research funding,the proportion of rural residents receiving higher education,the per capita electricity consumption in rural areas,and the per capita grain output were the main obstacle factors that restrict the improvement of new quality productive forces of grain.Based on this,measures such as strengthening agricultural technology support,cultivating high-quality"new farmers",promoting good farmland and laws,and implementing differentiated development were proposed to provide theoretical guidance for promoting the coordinated development of new quality productive forces of grain in various regions.关键词
