中国新质生产力与外贸新动能的耦合协调:时空特征、区域差异与驱动机制OA

The coupled and coordinated relationship between new quality productive forces and new drivers of foreign trade is a key impetus for promoting the high-quality development of China's foreign trade.Based on a systematic analysis of their coupling-coordination mechanisms,this study constructs a comprehensive analytical framework integrating the entropy method,the coupling coordination degree model,and the quadratic assignment procedure(QAP).Using panel data from 2013 to 2022,it empirically examines the coupling coordination level between the two systems,as well as their spatiotemporal evolution,spatial patterns,and driving factors of regional disparities. The results show that,overall,both new quality productive forces and new drivers of foreign trade exhibit a sustained upward trend,while significant regional disparities persist.The eastern region functions as a core growth engine with a higher coordination level,whereas the central,western,and northeastern regions remain relatively lagging.Temporally,the coordination degree evolves from mild imbalance toward primary coordination,with the eastern region taking the lead in entering a higher coordination stage.Spatially,a clear gradient pattern of"eastern leadership-central catch-up-relative lag in the western and northeastern regions"emerges.Global Moran's I indicates significant positive spatial auto correlation,suggesting a transition from polarization to diffusion effects.Further analysis reveals that disparities in digital economy development constitute the primary driver of coordination differences,while enhancing innovation capacity,stimulating consumption,strengthening the industrial base,and optimizing financial resource allocation are critical pathways for promoting regional coordination and upgrading the structure of foreign trade.
