Coupling Coordination Relationship between Livestock Supply and Feed Grain Production in China and It's Spatial-Temporal Differentiation
[Objective]To clarify coupling coordination relationship between livestock supply and feed grain production in China and its spatial-temporal differentiation is of great significance for guaranteeing national food security and boosting the high-quality development of the livestock industry.[Method]Based on the perspective of feed grain security,this paper firstly summarized the spatial-temporal char-acteristics of China's livestock supply and feed grain production.And then analyzed the spatial-temporal characteristics and correlation factors of China's livestock supply and feed grain production coupling coor-dination degree by comprehensively applying the coupling coordination degree model and grey correlation analysis.[Result]The coupling grade of China's livestock supply and feed grain production is generally at a high level of coupling,but there was a risk of downgrading and the spatial differentiation is not obvi-ous."Inversion"of the level of coordination from"intermediate level of coordination"to"primary level of coordination",with significant spatial differentiation in the level of coordination.Based on the primary correlation factor of coordination,it can be divided into means of production,system output,develop-ment support and infrastructure.[Conclusion]This paper argues that a four-pronged approach should be taken to strengthen the production base,adjust the nutritional supply structure,improve socialized services,and strengthen financial support,so as to promote China's livestock supply and feed grain pro-duction to reach a higher-quality and coordinated level.
