Scientifically evaluating net carbon dioxide (CO2) emissions is the pivotal strategy for mitigating global climate change and fostering sustainable urban development. Shaanxi Province situated in central China, boasts robust energy resources north a significant carbon-sink zone southern Qinling Mountains. Therefore, uncovering spatial distributions of CO2 identifying its influencing factors across cities would furnish crucial theoretical foundation advancing low-carbon development strategies. In this research, from 2005 to 2020 are calculated using carbon-emission-factor calculation model, then Geodetector utilized evaluate single-factor explanatory power two-factor interactions among fourteen various variables, econometric model employed analyze spillover effects these key factors. The results show following: (1) present regional differences ten Province, notably Xi’an City, Yulin Weinan which have recorded remarkable contributions with respective totals reaching 72.2593 million tons, 76.3031 58.1646 tons. (2) Regarding temporal trend changes, aggregate whole province underwent marked expansion 2019. City Shangluo exhibit surges, average annual growth rates soaring at 7.38% 7.39%. (3) From perspective factors, GDP exhibits most pronounced correlation spanning entire province. Meanwhile, foreign investment emerges as contributor specifically City. Moreover, interaction detection reveals factor combinations bi-enhancement, while few intricate non-linear enhancement. (4) SDM regression fixed-effect analysis reveal that city had positive effect on neighboring cities’ emission, scientific research technology services, along per capita construction land, notable negative spillovers, suggesting potential emission reduction benefits cities.

Buildings account for 39% of global carbon emissions, making the construction sector a pivotal contributor to climate change. In ecologically fragile plateau regions, tension between urban development and environmental sustainability poses significant challenge. This study examines spatiotemporal characteristics influencing mechanisms building emissions (BCEs) in cities using an empirical analysis 13-year panel data (2010–2022) from two municipalities six prefectures Qinghai Province, China. By employing eXtreme Gradient Boosting (XGBoost) model, we comprehensively assess drivers across four dimensions: socioeconomic structure, demographic factors, expansion patterns, climatic topographic attributes. Key findings include: (1) The XGBoost model exhibits robust predictive performance (R2 > 0.9, MSE < 0.1, RMSE 0.3), validating its effectiveness systems. (2) Socioeconomic structure significantly positively influence with GDP, per capita built-up areas being particularly influential. (3) interaction terrain increases buildings. (4) While is common factor affecting BCEs different types buildings, other such as population density, housing area, shape index, exhibit variability. These insights inform policy recommendations cross-regional flow balancing adaptive low-carbon planning strategies tailored ecosystems.
