Abstract:

The global Malmquist-Luenberger index was used to measure the green total factor productivity of the Yellow River Basin in China from 2001 to 2018, as a measure of the level of green development. Applying the nuclear density estimation, Theil coefficient, coefficient of variation, Dagum Gini coefficient and other research methods, the paper investigates the temporal and spatial evolution characteristics of the green development level in the Yellow River Basin. The research results show that the overall level of green development in the Yellow River Basin is not high, and it shows a slow wave-like rise. The driving force for growth comes from the progress of green technology; the differences within the basin are more obvious, downstream areas>upstream areas> the whole basin>midstream area in the average level of green development. The inter-provincial gap in the level of green development is gradually narrowing, and the distribution pattern is evolving from polarization to unipolarity. The overall development trend is "high-low-high". The characteristics of spatial differentiation are more obvious, showing that Shanxi and Henan as the core "dual-core" space imbalance feature. Based on the Theil coefficient, the gap in the level of green development within the Yellow River Basin is greater than the gap between the upstream, midstream, and downstream regions; based on the coefficient of variation, the overall level of green development level imbalance shows a downward trend; based on the Dagum Gini coefficient, the level of green development is spaced The overall imbalance is in a downward trend, and the gap is mainly due to regional differences, and the overlap between river basins has a relatively small impact on the overall gap in green development.

Key words: Yellow River Basin, green total factor productivity, spatio-temporal evolution, global Malmquist-Luenberger index
