摘要

In China, the New Quality Productive Forces (NQPF) and ecological restoration have become a national strategy. Investigating the interrelated mechanisms between NQPF and Territorial Spatial Ecological Restoration (TSERS) is essential for promoting high-quality development. We analyse the non-linear relationship between NQPF and TSERS employing fixed effects, moderating effects, and threshold models. The following results were observed: 1) The differences in NQPF among provinces gradually decreased and exhibited significant spatial agglomeration, while the differences in TSERS gradually increased and showed no significant spatial agglomeration; 2)The NQPF and TSERS of provincial units in China exhibited a centripetal clustering trend in the northeast-southwest direction; 3) China’s NQPF exhibited a significant and positive promotional effect on TSERS, with the regression coefficient of the main effect at 0.435 (including time-lagged effects); 4) There was a double threshold for the influence of NQPF on TSERS, with land green use efficiency being the threshold variable (the threshold values were 0.246 and 1.414, respectively); moreover, the influence of NQPF on TSERS gradually decreased after crossing the threshold value. We provide a novel perspective on examining the relationship between NQPF and ecological restoration while simultaneously evaluating the regulatory effectiveness of land green use efficiency in improving the broader scope of territorial ecological restoration. The findings suggest that the advancement of NQPF can significantly enhance TSERS. Policy recommendations include regulating the expansion of construction land, establishing criteria for ecological management, and implementing taxes on ecological restoration.
