中国粮食供需格局的历史变迁:从"南粮北调"到"北粮南运"
Historical Changes of Grain Supply and Demand Pattern in China:From"South-to-North Grain Flow"to"North-to-South Grain Flow"
摘要
Abstract
Ensuring stable and secure supplies of grain and essential agricultural products has al-ways been a paramount priority for building a strong agricultural power.It plays a crucial role in reinfor-cing the foundation of agriculture,rural areas,and farmers while safeguarding national security.From the perspective of a macro-historical view,the paper employs literature analysis and archival data to trace the changes of spatial-temporal patterns of grain supply and demand in China.The result shows that since the Song Dynasty,the"south-to-north grain flow"pattern gradually emerged and persisted for o-ver a millennium as a stable grain flow pattern of China.However,by the early 1990s,this began evol-ving into"north-to-south grain flow"pattern.Such shift fundamentally reflects adjustments in agricul-tural productivity distribution and the optimization of resource allocation efficiency.At present,China is committed to consolidating and enhancing the grain production capacity of advantageous regions.It is necessary to comprehensively recognize the public attributes of grain,implement primary responsibility for grain security,and promote the coordinated optimization of regional grain planting system.Additional-ly,efforts should focus on establishing an efficient grain industry circulation system and enhancing the governance mechanism of grain industry value chain,thereby providing effective support for the compre-hensive consolidation of grain security foundations.关键词
