[Spatial Distribution and Influencing Factors of Major Carbon Emission Enterprises in the Yellow River Basin]

The major carbon emission enterprises in the Yellow River Basin have the dual attributes of promoting economic growth and generating carbon emissions, which are important carriers to achieve high-quality development of the regional economy and the goal of the "dual-carbon" target. Based on the spatial location and socio-economic development data of the major carbon emission enterprises in the Yellow River Basin from 2001 to 2020, the evolution of spatial distribution, characteristics of agglomeration patterns, and spatial evolution of agglomeration of the major carbon emission enterprises were studied by using various spatial analysis methods, such as the standard deviation ellipse, kernel density estimation, Ripley's K function, etc. This was combined with the panel data regression model, and the effects of the basic, convenient, and elemental conditions on the spatial distribution of the major carbon emission enterprises were also explored. The results showed that： ① From 2001 to 2020, the number of the major carbon emission enterprises in the Yellow River Basin continued to grow, and their spatial distribution tended to expand in a single direction. The major carbon emission enterprises were closely clustered around the trunk and tributaries of the Yellow River, and the degree of agglomeration was different under different observation distances. The spatial morphological characteristics were presented as the 'monocenter and multi-zone' or 'multicenter and multi-zone,' which were conducive to the implementation of differentiated regulation policies in regard to the 'dual-carbon' target. ② From the perspective of the three types of conditions affecting the location selection of major carbon emission enterprises in the Yellow River Basin, the basic conditions dominated their spatial distribution, and the convenient conditions were conducive to their development. In the future, the elemental conditions would become the key variables to guide the reasonable growth of major carbon emission enterprises in the whole basin. These results suggest that structural adjustment and innovation promotion should be continuously strengthened to achieve the carbon control and reduction targets in the Yellow River Basin.
