Agriculture carbon-emission reduction and changing factors behind agricultural eco-efficiency growth in China

Huan Yang et al.

Summary: This study investigates the dynamics of agricultural carbon emissions (ACE) and agricultural ecoefficiency (AEE) in China, as well as the driving factors of AEE growth. Using provincial data from 2001 to 2018, the study finds that ACE has shifted from increasing to continuously decreasing after 2015, mainly driven by major grain-producing areas. It also reveals that the AEE growth mechanism changed after 2010, primarily due to technological progress. The improvement of agricultural infrastructure and human capital positively contribute to AEE growth, while public investment in agricultural R&D and agricultural industrial structure undermine it. Therefore, green-oriented policies and targeted agricultural public investments are needed to achieve both ACE reduction and AEE growth.

Spatiotemporal heterogeneity, convergence and its impact factors: Perspective of carbon emission intensity and carbon emission per capita considering carbon sink effect

Yu Cui et al.

Summary: This study analyzes the spatiotemporal heterogeneity, convergence, and impact factors of carbon emissions in the planting industry in China from 1997 to 2017. The results show significant differences in different regions and dimensions, and convergence characteristics vary depending on the indicators used.
