Research on the Coupling Coordination Relationship and Influencing Factors of the Agglomeration of New Energy Vehicle Industry and New Quality Productivity

Abstract

The dynamic interplay between the growth of the new energy vehicle (NEV) industry and the evolution of cutting-edge productive capabilities serves as a cornerstone for fostering top-tier progress. Together, these elements create a foundation essential for driving innovation and sustainable development in the modern economy. Using provincial-level panel data from China covering the period from 2012 to 2023, this study clarifies the coupling and coordination mechanisms between NEV industry agglomeration and the growth of novel high-quality productive forces. The coupling coordination between NEV industry agglomeration and new quality productive forces, and its influencing factors, are assessed using the entropy value method, entropy weight-TOPSIS, coupling coordination degree modeling, and geographic detectors. The results indicate that both NEV industry agglomeration and the development of new quality productive forces shows dynamic growth, marked by spatial variation. The coupled coordination of the NEV industry and new high - quality productive forces has transitioned from mild dissonance to near-dissonance, yet remains far from high-quality coordination, displaying a development pattern of "eastern and western regions leading, with central regions catching up." The primary drivers shaping the synergy between the agglomeration of the new energy vehicle (NEV) industry and the advancement of innovative productive forces are twofold: the economic development stage and the intensity of industrial clustering. Secondary influencing factors include the level of urbanization, the degree of government intervention, and green technology innovation. Combined influencing factors explain the development of coupling coordination better than any single factor.
