Abstract:
Based on the panel data of 273 prefecture level cities in China from 2009 to 2022, this study constructs a panel double fixed-effects model and a moderated model to test the influence mechanism of new quality productivity on carbon emission efficiency. The results showed that: ① The impact of new productivity on carbon emission efficiency was non-linear, with a "U" shape of first inhibition and then promotion, and had a significant impact. ② There was a significant moderating effect of industrial structure upgrading and human capital on the influence of new quality productivity on carbon emission efficiency. On the one hand, industrial structure upgrading and human capital promoted the impact of new quality productivity on carbon emission efficiency, and on the other hand, it shifted the inflection point of the impact of new quality productivity level on carbon emission efficiency to the right. ③ The effect of industrial structure upgrading on new productivity quality on carbon emission was heterogeneous in terms of resource endowment, environmental governance policy, and city scale. The research conclusion provides theoretical support and empirical evidence for the enhancement of industrial structure and human capital to give full play to the new quality productivity to enable the urban carbon emission efficiency under the "double carbon" goal.

Design Example: Sustainability in Concrete Building
There are multiple approaches to achieve sustainability in a commercial concrete building. For instance, construct a concrete parking area under the building, utilizing pervious concrete paver blocks in open areas to facilitate rainwater collection through an underground cistern.
