摘要
我国承诺在2030年前实现碳达峰,2060年实现碳中和,实现这一目标需要全社会共同努力,建筑业更是要积极转型升级,实现绿色可持续发展。钢结构属于典型的绿色环保节能型结构,符合循环经济和可持续发展的要求,近年来得到了快速发展,2020年钢结构产量达到了8900万t。通过对钢结构行业近年来的调研数据进行详细分析,阐述了钢结构行业的发展现状,重点分析了钢结构相关政策、加工区域特点、钢材品种及强度应用、钢结构应用领域、人均生产劳动率、行业集中度等,指出了双碳目标下我国钢结构行业的发展趋势及路径,对钢结构行业发展有重要指导作用。
China has promised to achieve a carbon peak by 2030 and carbon neutrality by 2060,which will necessitate significant efforts from the whole population.To achieve green and sustainable growth,the building sector should aggressively change and improve.Steel structures are typical green environmental protection and energy-saving structures that meet the needs of the circular economy and sustainable development.The steel structure industry has grown quickly in recent years,with steel structure output expected to reach 89 million tons by 2020.Based on a detailed analysis of survey data from the steel structure industry in recent years,this paper expounds on the development status of the steel structure industry,analyses steel structure related policy,area characteristics,steel varieties and strength application,application field,per capita labor rate,industry concentration degree analysis,and so on,and points out the development trend and path of China’s steel structure industry under the carbon peak and carbon neutrality target.
