摘要:

碳水关联分析是当前区域可持续发展研究的重要方向之一。从区域碳水耦合视角开展产业碳水足迹效率研究不仅有助于揭示资源利用强度和效率对产业碳排放的影响机制,而且对于全球化背景下区域产业转型中的节水和碳减排具有重要的实践意义。采用2012年河南省投入产出表及各产业取水量和能源消费数据,利用投入产出分析对不同产业的碳水足迹效率进行了对比研究。主要结论如下:(1)碳足迹和水足迹存在着行业不匹配现象。其中,农业水足迹最大,是水足迹最小的木材业的2333倍;采掘业碳足迹最大,是碳足迹最小的食品业的273倍。(2)不同产业碳水足迹效率具有较大的差异。一般来说,足迹较大的产业其足迹效率偏低。(3)产业碳水足迹效率的差异主要受产业属性、水能消耗强度、能源结构、企业技术水平及产业关联情况等因素的影响。(4)建议未来河南省应结合不同产业的特点及水能关联情况制定差别化的节水与碳减排政策,加强制度约束和法律监管,推动企业水能资源高效利用,进一步增强区域适应和减缓气候变化的能力。

Abstract:

Water-carbon nexus is one of the important research fields of regional sustainable development. Studies on industrial carbon and water footprint efficiency from the perspective of water-carbon coupling not only help reveal the impact mechanism of the resource consumption intensity and efficiency on industrial carbon emissions, but also have great significant practical meanings for reducing water and carbon emissions in regional industrial transformation under the background of globalization. By the method of input-output analysis, input-output table of Henan in 2012 and industrial water and energy consumption data were applied to discuss industrial carbon and water footprint efficiency in this paper. The conclusions are as follows: (1) Carbon and water footprints of different industries are unmatched. The agricultural water footprint is the largest, which is 2333 times of the water footprint of lumbering. The carbon footprint of extractive industry is the largest, which is 273 times of food industry. (2) There are obvious differences among industrial water and carbon footprint efficiency. In general, the water/carbon footprint efficiency is lower in the industries with higher water/carbon footprint. (3) The different water/carbon footprint efficiency among different industries were mainly influenced by industry attribute, water and carbon consumption intensity, energy structure, technological level and relationship between industries, etc. (4) In the future, Henan province should make differentiated water-saving and carbon emission reduction policies in industrial development by combining the characteristics of different industries and the water-energy nexus, strengthening institutional constraint and legal supervision, promoting water and energy efficiency of enterprises, and enhancing regional adaptation and mitigation capacity under climate change.
