Research on Influencing Factors of Carbon Emissions in the Regional Construction Industry: A Case Study of Jiangxi Province

This study focuses on carbon emissions (CE) in the construction industry of Jiangxi Province. Using the emission factor method, it calculates the CE throughout the entire lifecycle of the construction sector and analyzes the trends and characteristics of emissions from 2008 to 2021. Grey correlation analysis and the STIRPAT model are employed to identify key influencing factors of CE, followed by corresponding emission reduction strategies and recommendations. The results show that CE from Jiangxi’s construction industry increased by 6.25 times between 2008 and 2021, with building material consumption and residential buildings accounting for 80% of the total lifecycle emissions. Key influencing factors include the gross output value of the construction industry, per capita GDP, regional population, and the level of green technology innovation, with the latter exhibiting an inhibitory effect on CE.
