中国高标准农田建设政策对口粮自给率的影响
Influences of China's high-standard farmland construction policies on rations'self-sufficiency rate
摘要
Abstract
This study used balanced panel data from 26 provinces from 2003 to 2022 to discuss the impact of the self-sufficiency rate of high-standard farmland construction policies.By constructing a continuous dual differential model,this study analyzed the specific impact of high-standard farmland construction policies on self-sufficiency in staple food and further explores the underlying mechanisms.The results showed that high-standard farmland construction policies had a significant positive effect on increasing self-sufficiency in staple food,and this conclusion had passed robustness tests.Heterogeneity analysis showed that the policy implementation effect was more obvious in grain-producing areas,and the effect in eastern China,central China,and western China regions declined in order.Mechanism verification showed that high-standard farmland construction policies promoted self-sufficiency in staple food by promoting land circulation and agricultural mechanization.Researches showed that high-standard farmland construction policies could promote self-sufficiency in staple food,this promotion had a lag and persistence,meanwhile,it was closely related to the positioning of grain production functional zones and geographical location.It is suggested that the new round of high-standard farmland construction should be implemented in accordance with the highest standards,with due consideration given to the specific conditions of different regions.Emphasis should be placed on land transfer and mechanization upgrades,with efforts made to strengthen post-construction management of high-standard farmland to ensure absolute food security and enhance food security guarantees.关键词
