Research on influencing factors of urban building carbon emissions based on STIRPAT model——taking Suzhou as an example

The research on the influencing factors of carbon emissions from urban buildings is of great significance for the reduction of carbon in the urban building sector and even the realization of the city’s the carbon peak and neutrality goals. In this paper, combined with the ridge regression method, the STIRPAT model is used to establish a new model for influencing factors of building carbon emissions in Suzhou, and the factors such as urbanization rate, the number of permanent residents, per capita construction and tertiary industry added value, and per capita disposable income are analyzed. The analysis results show that the urbanization rate is the primary driving factor for building carbon emissions in Suzhou, followed by the number of permanent residents, then the added value of the per capita construction industry and tertiary industry, and finally the per capita disposable income. The conclusions of this paper indicate that industrialization and urbanization have strongly promoted the growth of building carbon emissions in Suzhou. In the future, with the continuous development of industrialization and urbanization and the increase of population, Suzhou City can rationally plan urban development boundaries to promote green and low-carbon transformation and development in the field of urban and rural construction, improve residents’ low-carbon awareness, and advocate green and low-carbon behavior of residents to reduce building carbon emissions.
