建筑企业数字化转型与碳减排：基于上市公司的证据

s a key field of energy consumption and carbon emission, the construction industrys carbon emission reduction measures have important strategic significance for achieving the goal of "double carbon". Based on the data of listed construction enterprises in China from 2000 to 2021, this paper empirically explores the effect and path of digital transformation on carbon emission reduction. The results show that digital transformation can significantly reduce the carbon emission intensity of enterprises, and it is mainly achieved through three paths: promoting green technology innovation, improving total factor productivity and optimizing production process and management structure. Heterogeneity analysis reveals that the effect of digital technology on emission reduction of enterprises with fierce competition in the industry is more significant, but the difference between regions is not significant. Further research shows that emerging technologies such as artificial intelligence and blockchain have more emission reduction potential than traditional information tools. The conclusion of this paper provides policy implications for the carbon-neutral path in the construction field.
