摘要
建筑业是京津冀地区主要的钢铁消费领域。本研究以动态物质流分析为基础,测算了1949~2016年京津冀地区房屋建筑中的钢铁存量,并在此基础上,初步探索了驱动钢铁存量变化背后的因素。结果显示:2016年,京津冀地区北京市房屋建筑中钢铁存量为52.9 Mt,天津市为46.3 Mt,河北省为142.8Mt。在房屋建筑中人均钢铁存量方面,2016年,天津市为2 961.8kg/人,而北京市为2 434kg/人,河北省仅为1 911.8kg/人。2000~2016年,经济是促进京津冀地区房屋建筑中钢铁存量增加的最大因素,其次是人口因素;钢铁服务效率因素对河北省房屋建筑中钢铁存量增加的驱动强度在逐渐增强,而对北京市和天津市的驱动强度在减弱。
The construction industry is the main steel consumption field in the Beijing-Tianjin-Hebei region.Based on dynamic material flow analysis,this study measured the stock of steel in housing construction in the Beijing-Tianjin-Hebei region from 1949 to 2016.On this basis,the factors behind the changes in steel stocks were initially explored.The results show:in 2016,the stock of steel in Beijing s housing construction was 52.9 Mt,Tianjin is 46.3 Mt,and Hebei province is 142.8 Mt.In terms of per capita steel stock in housing construction.In 2016,Tianjin was 2 961.8 kg/per,while Beijing residents was 2 434 kg/per,and Hebei province was only 1 911.8kg/per.From 2000 to 2016,the economy was the biggest factor contributing to the increase in steel stocks in housing construction in the Beijing-Tianjin-Hebei region,followed by population factors.The driving efficiency of steel service efficiency factors is increasing for the increase of steel stock in housing construction in Hebei province,while the driving strength for Beijing and Tianjin is weakening.
