[Spatio-temporal Evolution Characteristics and Influencing Factors of Industrial Carbon Emissions in Gansu Province]

The secondary industry is an important economic pillar in Northwest China， and industry is an important driving force for the development of Northwest China， and the change of industrial energy consumption has a significant impact on the regional carbon cycle and climate change. Taking Gansu Province as an example， based on the statistical data of 2000-2023， the carbon emissions of energy consumption and industrial energy consumption in Gansu Province were measured by using the greenhouse gas emission coefficient method and the city-scale inventory algorithm. By analyzing the carbon emissions of each city （prefecture）， the growth trend and spatiotemporal evolution characteristics of carbon emission intensity in Gansu Province were studied， and the influencing factors were analyzed by using geographic detectors and spatiotemporal geographically weighted regression models. The results show that： ① The carbon emissions of industrial energy consumption in Gansu Province showed an overall upward trend from 2000 to 2023， increasing from 7 185.21×10⁴ t to 23 675.22×10⁴ t. ② Based on the SLOPE calculation results， the carbon emission areas in Gansu Province could be divided into four categories： rapid growth， medium growth， slower growth， and slow growth. ③ The proportion of fossil energy consumption， the level of urbanization， carbon emission productivity， and the carbon intensity of industrial investment were the key factors driving the continuous growth of industrial energy consumption and carbon emissions in Gansu Province.
