摘　　要：基于“双碳”目标下我国建筑业实现脱碳减排的要求,利用STIRPAT模型建立时空地理加权回归模型,从时空异质性的角度考察我国30个省市的建筑业技术创新、所有制结构等变量对建筑业碳排放的时空交互作用及影响差异。研究发现:2011—2021年技术创新对中国30个省市建筑业碳排放的抑制作用,呈先减后增的波动变化趋势,且从东三省向长三角一带转移。国有制主导的所有制结构对多数省份建筑业碳排放的影响,由抑制逐渐转为促进。但建筑业企业国有制对新疆地区碳排放的影响系数呈逐年减小的正向趋势,建筑业碳排放的增长速度得到了有效控制。研究结果可为相关部门加强建筑业技术创新交流,因地制宜调整优化所有制结构提供理论依据。Based on the requirements of China's construction industry to achieve decarbonization and emission reduction under the"double carbon"target,the STIRPAT model is used to establish a spatio-temporal geographically weighted regression model.From the perspective of spatio-temporal heterogeneity,the spatio-temporal interaction and influence differences of technological innovation,ownership structure and other variables in the construction industry of 30 provinces and cities in China on carbon emissions in the construction industry are investigated.The study found that the inhibitory effect of technological innovation on the carbon emissions of the construction industry in 30 provinces and cities in China from 2011 to 2021 showed a fluctuating trend of decreasing first and then increasing,and the trend shifted from the three northeastern provinces to the Yangtze River Delta.The impact of the ownership structure dominated by state ownership on the carbon emissions of the construction industry in most provinces has gradually shifted from inhibition to promotion.However,the influence coefficient of state-owned construction enterprises on carbon emissions in Xinjiang is decreasing year by year,and the growth rate of carbon emissions in the construction industry has been effectively controlled.The research results can provide a theoretical basis for relevant departments to strengthen technological innovation exchanges in the construction industry and adjust and optimize the ownership structure according to local conditions.
