Abstract
The Yellow River Basin is an important energy production base, heavy industry base, and grain production area in China. Meanwhile, the ecological environment in this area is also very fragile. The success of carbon emission control in this region is related to whether China can complete its vision of carbon peak and carbon neutralization on time. Taking carbon emissions as the non-ideal output of the economy into the nonparametric DEA Malmquist index model, this paper measures the green Malmquist index of 9 provinces in the Yellow River Basin from 2014 to 2020 and analyzes the impact of the green Malmquist index, green technology efficiency and green technology progress rate on the regional economic growth gap and its time evolution trend. The results show that the green total factor productivity of the region shows a fluctuating upward trend from 2014 to 2020, but the direction of efficiency progress is negative. Therefore, the Yellow River Basin needs to reform the management system of high energy-consuming industries and strengthen environmental supervision in the future. In addition, the changes in green total factor productivity in various provinces show high heterogeneity, which poses new challenges to the formulation of emission reduction policies.
