数字新质生产力与饲料产业链现代化发展耦合协调的时空演进与影响因素OA

Based on panel data from 30 Chinese provinces from 2015 to 2025,this article constructed an evaluation index system for digital new quality productive forces and feed industry chain modernization development.The entropy weight method,coupling coordination degree model,three-dimensional kernel density estimation,and quadratic assignment procedure(QAP)were employed to empirically examine the coupling coordination level,spatiotemporal evolution characteristics,and influencing factors of the two systems.The results showed that the overall coupling coordination level between digital new quality productive forces and feed industry chain modernization development exhibited a rising trend,transitioning from mild imbalance(0.305)to barely coordination(0.505)at the national level,with a regional distribution pattern of'eastern>central>western'in a gradient-decreasing order.The three-dimensional kernel density estimation revealed that the coupling coordination degree across the nation and the three major regions gradually improved.However,absolute differences still existed,and the polarization trend remained relatively pronounced.In terms of influencing factors,disparities in business environment,digital infrastructure,digital finance,and digital transformation all exerted significant positive promoting effects on the formation of spatial correlation networks in the coupling coordination between the two systems,while disparities in price fluctuations of feed production materials exerted a significant inhibitory effect,and the intensity of these influencing factors exhibited marked regional heterogeneity.The study shows that narrowing regional disparities in digital finance development,optimizing the business environment,improving digital infrastructure,and accelerating industrial digital transformation are effective pathways for promoting in-depth coupling coordination between digital new quality productive forces and feed industry chain modernization development.
