为了明确CO2排放的空间特征，将空间单元的经济外部性移植到CO2排放研究中。在此基础上，基于节能减排的专利数据构建了空间计量模型，以识别减排路径。结果表明：(1)中国CO2排放的核密度图呈现出明显的右厌恶状态，且峰值越来越低；因此，我们可以得出结论：中国的二氧化碳排放量在不断增加，二氧化碳排放两极分化严重；(2)由于空间单元上存在相似性和连通性，从全球和局部角度看，中国CO2排放均表现出稳定的空间集聚效应；(3)基于相邻、地理和经济距离矩阵，从节能减排专利数据的角度来看，能源技术进步对中国二氧化碳排放具有正向减排作用。最后，在上述结论的基础上，提出了相应的政策含义。(C) 2018 Elsevier Ltd.版权所有。
To clarify the spatial characteristics of CO2 emissions, economic externalities of spatial units are transplanted into CO2 emissions research. Furthermore, to identify emissions reduction pathways, spatial econometric models are constructed based on the patent data about energy conservation and emissions reduction. The key results are: (1) The kernel density plot of China's CO2 emissions shows an obvious right-averse state, and the peak is getting lower. Therefore, we can conclude that CO2 emissions in China are increasing, and polarisation of CO2 emissions is serious; (2) Due to the similarity and connectivity exist in spatial units, China's CO2 emissions have shown a stable spatial agglomeration effect from global and local perspectives; (3) Based on adjacent, geographic, and economic distance matrices, energy technological progress has played a positive emissions reduction role on China's CO2 emissions from the perspective patent data about energy saving and emissions reduction. Finally, on the basis of the above conclusions, some policy implications have been proposed accordingly. (C) 2018 Elsevier Ltd. All rights reserved.
