Abstract

Abstract

To support the ecological protection， high-quality development， and the achievement of the Dual Carbon Goals in the Yellow River Basin， this study systematically investigated the spatiotemporal variations and regional disparityies of carbon emissions in the basin. Drawing on carbon emission data from 69 prefecture-level cities in the Yellow River Basin for the period 1997 to 2020， this study employed methods including the Theil index， kernel density estimation， standard deviational ellipse， and Moran's I index. The results indicated that the total carbon emissions in the Yellow River Basin exhibited an overall upward trend from 1997 to 2020， but the growth rate reduced significantly after 2011. Notable regional disparities existed but gradually narrowed： carbon emissions in the upper reaches grew the fastest， followed by those in the middle reaches， while those in the lower reaches remained relatively stable. In terms of spatial distribution， the center of carbon emissions shifted westward， and the distribution pattern transitioned from agglomeration to dispersion， with the spatial agglomeration effect weakening over time. Moran's I index revealed a significant positive spatial autocorrelation of carbon emissions， although this agglomeration effect also showed a weakening trend. Based on these findings， this study proposed formulating differentiated emission reduction policies for the upper， middle， and lower reaches of the basin and strengthening regional collaborative governance， thereby providing a scientific reference for promoting the green and low-carbon transformation of the Yellow River Basin.
