Spatiotemporal evolution characteristics and influencing factors of soybean production in China
Journal Title: Journal of Henan Agricultural University - Year 2023, Vol 57, Issue 5
Abstract
[Objective] The study was carried out to explore the spatiotemporal evolution and influencing factors of soybean production realize the optimization of soybean regional layout and ensure food security. [Method] Using the annual data of the provinces from 1997 to 2020, this paper analyzes the spatial correlation of soybean production with the methods of spatial Gini coefficient, industrial concentration, location entropy and spatial autocorrelation to establish a dynamic spatial panel Durbin model to study the impact of driving factors on the spatial-temporal evolution of soybean production. [Result] There are positive spatial correlation in soybean production. The average soybean yield, natural disaster rate and urbanization rate have a significant promotion effect on soybean production in the local and adjacent areas in the short term, but have an inhibitory effect the long term. In the short term, the improvement of soybean technology level and chemical fertilizer application rate have a significant inhibitory effect on soybean production in the local area and adjacent areas. In the long term, the soybean technology level has a significant promoting effect on the soybean production in the local and adjacent areas. The direct effect of fertilizer application on soybean production is significantly positive, while the spatial effect is not significant. [Conclusion] Fully considering the spatial effect of soybean production and guiding the region to improve the reasonable spatial allocation of each input factor will be conducive to promoting the improvement of soybean production capacity and ensuring the security of soybean supply.
