Spatial and Temporal Variation of Carbon Emissions and Regional Inequality of Public Buildings in China
By utilizing provincial panel data of public buildings in China from 2010 to 2020, this study explored the spatial and temporal variation of carbon emissions from public buildings, the inequality of carbon intensity and its drivers at two measures. The following results were obtained:(1) Carbon emissions per capita increased and carbon emissions per unit of floor area decreased during the sample period, and carbon emissions of public buildings in hot summer and cold winter regions, and cold regions were significantly higher than those in other regions. The carbon emission center of gravity was generally located in the northeast of the energy consumption center of gravity.(2) The overall spatial agglomeration effect of carbon emissions of public buildings developed in an inverted "U" shape, and the local effect of "low-low agglomeration" is the main agglomeration pattern.(3) The overall regional variation in carbon emission intensity of public buildings consisted mainly of intra-regional variation. Building climate zones contributed progressively to the spatial variation in per capita carbon emissions.(4) The value added of services per capita was the major contributor to the inequality of carbon emission intensity of public buildings, with a rate of about 70% (±5%).
