China's construction industry confronts with the dilemma of carbon emissions in adjusting the environmental regulations. Many studies are neglected on discovering the potential nexus amongst environmental regulations (ERs), technological innovation (TI) and CEI (CEI) and ignores the relationships amongst TI for reducing CEI. To mitigate this gap, this study bridges institutional theory to integrate the practices in the construction industry. This study applies a panel dataset on the construction industry from 30 provinces during 2004-2018 and uses it with a two-step system-generalised method of moments for analysis. The proposed method enables the prevention of the interference of the heteroscedasticity problem and improves certain analytical efficiency. The results are as a guideline for policymakers in rechecking the policies and regulations adequacy. The findings indicate that (1) the forced emission reduction effect is proven by command-and-control and market-based ERs, which can inhibit CEI; (2) voluntary ERs have an inverted U-shaped nexus with CEI; in other words, the green paradox effect shifts to the forced emission reduction effect once the intensity of voluntary ERs increases; and (3) market-based and voluntary ERs reduce CEI effectively by using TI as the mediator in construction industry.
中国建筑业在调整环境法规方面面临碳排放困境。许多研究忽视了探索环境法规（ERs）、技术创新（TI）和碳排放强度（CEI）之间的潜在联系，也忽略了技术创新在降低碳排放强度方面的相互关系。为了弥补这一差距，本研究将制度理论与建筑业的实践相结合。本研究应用了2004年至2018年期间30个省份建筑业的面板数据集，并采用两步系统广义矩估计方法进行分析。所提出的方法能够防止异方差问题的干扰，并提高一定的分析效率。研究结果可为政策制定者重新审视政策法规的充分性提供指导。研究结果表明：（1）命令控制型和市场型环境法规证明了强制减排效果，能够抑制碳排放强度；（2）自愿性环境法规与碳排放强度呈倒U形关系；换句话说，一旦自愿性环境法规的强度增加，绿色悖论效应就会转变为强制减排效应；（3）在建筑业中，市场型和自愿性环境法规通过将技术创新作为中介有效地降低了碳排放强度。
