Abstract:Against the backdrop of China entering a new stage of development, implementing new development concepts, and building a new development pattern, how to pursue healthy industrial development while controlling water energy consumption and reducing carbon emissions has become an important and urgent practical task. On the base of exploring deep level industrial economic connections, the theoretical framework of the three-dimensional full footprint stereoscopic correlation of industry water energy carbon was constructed. Then the article designed an input-output calculation model for industrial factor footprints and created a function correction input-output table to solidify the data foundation. Selecting Chinese industries from 2002 to 2022 as the research object, the three-dimensional full footprint of industrial water, energy, and carbon were calculated. Based on the three dimensional full footprint stereoscopic correlation network of water energy carbon in Chinese industries, the evolution characteristics of network attributes and relationship structures have been compared and analyzed by combining dynamic and static methods. The results showed that:(1) During the research period, the average annual growth rate of China's industrial water, energy, and carbon total carbon footprint had decreased, but the total amount had increased significantly. The increase in water footprint was mainly due to the increase in industrial direct footprint, while the increase in energy footprint and carbon footprint were due to the increase in industrial indirect footprint. (2) There were significant differences in the three-dimensional footprint of water energy carbon and dual factor among various industries, and it was necessary to integrate the characteristics of industries and footprint characteristics to improve the efficiency of factor utilization. (3) During the research period, various indicators and coupled performance of the industrial water energy carbon network had improved, but the circular sustainability, symbiosis and mutual benefit, and correlation had not reached the ideal state.
