Spatial Correlation Network and Driving Effect of Carbon Emission Intensity in China's Construction Industry

To explore the spatial network structure characteristics and driving effects of carbon emission intensity in China's construction industry, this paper measures the carbon emission data of China's construction industry in various provinces from 2006 to 2017 and then combines the modified gravity model and social network analysis method to deeply analyze the spatially associated network structure characteristics and driving effects of the carbon emission intensity in China's construction industry. The results show that the regional differences of the carbon emissions of the construction industry are significant, and the carbon emission intensity of the construction industry shows a fluctuating trend. The overall network of carbon emission intensity shows an obvious core-edge state, and the hierarchical network structure is gradually broken. Economically developed provinces generally play a leading role in the network and play an intermediary role to guide other provinces to develop together with them. Among the network blocks, most of the blocks play the role of brokers. The block with the leading economic development has a strong influence on the other blocks. The increase in network density and the decrease in network hierarchy and network efficiency will reduce the construction carbon emission intensity.

Automated summary

This study explores the spatial network structure characteristics and driving effects of carbon emission intensity in China's construction industry. By measuring the carbon emission data of China's construction industry in various provinces from 2006 to 2017, the study combines the modified gravity model and social network analysis method to analyze the spatially associated network structure characteristics and driving effects of carbon emission intensity. The results show significant regional differences in carbon emissions in the construction industry and a fluctuating trend in carbon emission intensity. The overall network exhibits a core-edge state, with economically developed provinces playing a leading and intermediary role. Increasing network density, reducing network hierarchy, and improving network efficiency can help reduce construction carbon emission intensity.
