| 为探究农业产业集聚对碳效率的作用机理，本研究基于随机前沿超越对数生产函数将农业碳排放纳入到农业经济核算体系之中，利用1997—2014年的面板数据对中国省域农业碳效率进行考察，并借助空间计量经济方法对农业碳效率的空间相关性及其与农业产业集聚的关系进行分析。结果表明，样本考察期内中国农业碳效率稳步增长，但受"梯度"发展模式的影响，农业碳效率具有以东部为高值"极核"区和以西部为低值"外围"区的分布结构特征。同时，区域内省份间农业碳效率的依赖性明显。而对农业产业集聚与农业碳效率关系初探后，发现二者之间整体上存在环境库兹涅茨曲线关系特征，即随着农业产业集聚度的提高，农业碳效率呈现出先得到改善后不断恶化的变化趋势。同时，处于不同集聚度下的群组情况各异，其中农业高集聚度区（中西部农业主产区）的农业碳效率随农业产业集聚度提高表现出"先升后降"的曲线特征，而在农业低集聚度区（东部经济发达区），农业产业集聚提高对农业碳效率的改善作用明显。 |

| Abstract: |
| In order to inspect the effects of agricultural agglomeration on agricultural carbon efficiency, based on the stochastic frontier transcendental logarithmic production function, this study integrated agricultural carbon emissions into the agricultural economic accounting system to calculate provincial agricultural carbon efficiency of China from 1997 to 2014, and then investigated the spatial auto-correlation of agricultural carbon efficiency and its relationship with agricultural agglomeration. The results showed that:Although the carbon efficiency of China's agriculture was increased steadily during the study period, the regional carbon efficiency distribution structure featured by "polar nuclear" area with high value in the eastern part and the western low value was gradually formed due to the long-term influence of "gradient type" development mode, and the imbalance of inter-provincial carbon efficiency became more serious. Meanwhile, agricultural carbon efficiency between provinces in the same region was relatively dependent; Based on the investigation of relationships between agro-industry agglomeration and agricultural carbon efficiency, it was found that there was a characteristic of environmental Kuznets curve between them, which is with the increase of agricultural industry agglomeration, the agricultural carbon efficiency would be improved and then be deteriorated. At the same time, different regions with different relationships between agro-industry agglomeration and agricultural carbon efficiency showed different agglomeration degrees, which meant that the agricultural carbon efficiency of high agricultural agglomeration zone (central and western agricultural advantageous provinces) displayed "rising-decreasing" tendency with the increase of agricultural agglomeration degree. However, in low agricultural agglomeration area (developed coastal areas), the agglomeration of agricultural industry displayed a significant effect on the improvement of agricultural carbon efficiency. |
