设施农业发展对农业碳排放效率的影响

This study evaluates agricultural carbon emission efficiency (ACEE) and the current development status of facility agriculture, exploring its impact on agricultural carbon emission efficiency. Employing the super-efficiency SBM model, we measured ACEE across the agriculture, animal husbandry, and fisheries sectors, and analyzed the results using kernel density estimation. An entropy weight method was applied to construct the Facility Agriculture Development Index (FADI) for evaluation. An empirical study using the STIRPAT panel regression model examined the specific effects of facility agriculture on ACEE. The findings indicated that between 2010 and 2020, the national average ACEE improved by 49.13%, with significant increases in the eastern (56.72%) and western (52.96%) regions. Most provinces experienced growth in facility agriculture, averaging 2.88%, though economically developed regions lagged behind less developed ones. The STIRPAT model results highlighted a significant positive impact of facility agriculture development on ACEE, with contributing factors such as economic growth, population increase, and industrial structure upgrading. However, this positive effect was currently observed only in the eastern region, while the western, northeastern, and central regions still experienced negative effects. The research indicated that facility agriculture development positively influences national agricultural carbon emission efficiency, primarily driven by the eastern region, though disparities in ACEE and modernization levels persist across regions.
