农业生态效率对碳减排的影响及对策
Analysis and countermeasure research on the influence of agricultural ecological efficiency on carbon emission reduction evaluation from the perspective of Dual Carbon Goals in China
摘要
Abstract
As a fundamental and strategic industry in China's national economy,agriculture played a crucial role and undertakes significant responsibilities in safeguarding the country's"Five Major Securities".Simultaneously,under the"Dual Carbon"goals(carbon peaking and carbon neutrality),it exhibited the dual attributes of being both a carbon source and a carbon sink.In-depth exploration of the impact of agricultural eco-efficiency on carbon emission reduction held significant theoretical and practical significance for promoting China's carbon emission reduction efforts and the achievement of the Dual Carbon goals.In view of the current lack of correlation analysis between agricultural eco-efficiency and carbon emission reduction evaluation,based on the panel data of 296 prefecture-level administrative divisions in China from 2000 to 2023,this study measured the agricultural eco-efficiency of these prefecture-level administrative divisions using the super-efficiency Slack-Based Measure(SBM)model.It empirically analyzed the mechanism through which agricultural eco-efficiency affects carbon emission reduction by employing the two-way fixed effects model,moderating effect model,mediating effect model,and spatial model.The results showed the following findings:1)China's agricultural eco-efficiency exhibited an overall upward trend from 2000 to 2023,increasing from 0.155 in 2000 to 0.423 in 2023,with a growth rate of 172.9％.In terms of spatial distribution,it generally presented a pattern of"higher in the south,lower in the north";2)Agricultural eco-efficiency contributed to promoting the carbon emission reduction effect,and this impact remained significant even after undergoing endogeneity tests and robustness tests using multiple methods;3)In the mechanism of agricultural eco-efficiency on carbon emission reduction,the level of Internet access and educational level played positive moderating roles;4)The promoting effect of agricultural eco-efficiency on carbon emission reduction was more pronounced in the western region and the grain production-consumption balance regions;5)Agricultural eco-efficiency indirectly achieved the carbon emission reduction goal by improving agricultural labor productivity,enhancing educational capacity,and raising the level of village governance;6)Agricultural eco-efficiency demonstrated a spatial spillover effect on carbon emission reduction.Since agricultural eco-efficiency is conducive to promoting carbon emission reduction,this study puts forward the following suggestions to advance carbon emission reduction:formulate differentiated development strategies for agricultural eco-efficiency in accordance with local conditions,strengthen the construction of agricultural carbon emission reduction-related infrastructure and the promotion of relevant technologies,establish a regional collaborative governance systems,and improve the policy support and guarantee system for low-carbon agriculture.关键词
