Abstract
The enhancement of carbon emission efficiency is a crucial pathway for achieving the "dual carbon" goals， which relies on the in-depth participation of new quality productivity （NQP）. Based on provincial panel data from 2011 to 2022， this study empirically examined the impact， mechanisms， and effects of NQP on carbon emission efficiency， using the two-way fixed effects model， mediation effects model， panel threshold model， and quantile regression model. The findings indicated that： ① NQP significantly improved carbon emission efficiency. ② Mechanism analysis revealed that NQP enhanced carbon emission efficiency by facilitating the aggregation of innovative talent and innovative capital. ③ Threshold effect analysis showed that the influence of NQP on carbon emission efficiency exhibited significant threshold characteristics. When the government's emphasis on science and technology and the local market scale exceeded certain thresholds， the effect on improving carbon emission efficiency became more pronounced. ④ Heterogeneity analysis indicated that the effect of NQP on enhancing carbon emission efficiency was more pronounced in regions with substantial investment in regions with higher levels of government environmental emphasis and digital infrastructure. ⑤ Further analysis suggested that the influence of NQP on carbon emission efficiency also exhibited a notable catching-up effect， which helps narrow the regional disparities in carbon emission efficiency. These conclusions provide a new theoretical perspective and clearer policy guidance for promoting the green low-carbon transformation of economic development models.
