气候变化呼唤着全球公众的关注和努力，以减少二氧化碳排放，实现全球可持续发展。建筑业作为我国最大的能源消费国之一，在实现国家碳减排目标中发挥着至关重要的作用。本文利用改进的卡亚模型，考察了中国建筑业碳排放、能源消费、GDP增长率和碳排放强度之间的关系和趋势。结果表明，建筑业的碳排放主要受建设规模GDP增长的影响。能源消费是碳排放增加的主要驱动力。随着经济的发展和建设规模的增加，单位面积碳排放量和碳强度呈下降趋势。建筑活动对化石燃料的依赖仍然存在，尽管明显减少。能源强度有助于减少建筑业碳排放。建筑业低碳经济的发展呼唤技术创新、替代能源和新技术支撑的进一步突破。这些发现为中国建筑业的碳排放提供了科学证据，并为特定行业的排放法规提供了有用的参考。
Climate change calls for worldwide public concern and effort to cut down carbon dioxide (CO2) emissions and globally realize sustainable development. As one of the largest energy consumers, the construction industry plays a crucial role in achieving the national carbon emission reduction goal. This paper, by employing an improved Kaya model, explored the relationships and trends among carbon emission, energy consumption, and GDP growth rate and carbon emission intensity of the Chinese construction industry. Results showed that the carbon emission of the construction industry is mainly affected by GDP growth of construction scale. The energy consumption was the main driver to the increase of carbon emissions. The carbon emissions of unit area and carbon intensity showed a decreased trend with the development of economy and the increase of construction scale. The dependence of construction activities on the fossil fuel remained despite noticeable decrease. Energy intensity helps to reduce construction carbon emissions. Low carbon economy development of construction industry calls for technological innovation, alternative energy and new technical support for further breakthrough. These findings provide scientific evidence of carbon emissions in the Chinese construction industry and useful inputs for industry-specific emission regulations.
