摘要: 基于中国30个省(市、自治区)2002—2016年的面板数据,运用空间计量模型和面板门槛回归模型,从空间相关性和空间异质性两个角度分析农业生产效率对农业碳排放的影响。结果发现:第一,农业生产效率对农业碳排放具有显著的负向影响。第二,基于相邻矩阵、距离矩阵和经济矩阵,农业碳排放对周边省份具有显著负的空间溢出效应;基于相邻矩阵和经济矩阵,农业生产效率对周边省份都具有显著正的空间溢出效应。第三,不同的省份之间随着农业产值的提高,农业生产效应对农业碳排放的影响呈现先上升后下降的倒“U”型特征。不同省份之间随着农业生产效率的提高,农业生产效率对农业碳排放具有显著负向影响,且其影响程度呈不断下降趋势。提高农业生产效率能够有效的减少碳排放,对实现农业高质量发展具有重要意义。

Abstract: Based on the panel data of China's 30 provinces (cities, districts) from 2002 to 2016, this paper uses spatial econometric model and panel threshold regression model to analyze the influence of agricultural production efficiency on agricultural carbon emissions. The results show that: first, agricultural production efficiency has a significant negative impact on agricultural carbon emissions; second based on adjacent matrix, distance matrix and economic matrix, agricultural carbon emissions have significant negative spatial spillover effects on neighboring provinces; third, with adjacent matrix and economic matrix, agricultural production efficiency has a significant positive spatial spillover effect on neighboring provinces. With the increase of agricultural output value in different provinces, the impact of agricultural production on agricultural carbon emissions shows an inverted U-shaped characteristic that first rises and then falls. With the improvement of agricultural production efficiency in different provinces, agricultural production efficiency has a significant negative impact on agricultural carbon emissions, and its impact degree is declining. Therefore, improving agricultural production efficiency can effectively reduce carbon emissions, which is of great significance for achieving high-quality agricultural development.

Key words: agricultural production efficiency, agricultural carbon emissions, Moran’s I, spatial spillovers, threshold characteristics
