Net ecosystem productivity （NEP） is an important indicator for evaluating carbon sources and sinks in regional ecosystems. Clarifying its spatiotemporal differentiation pattern and driving mechanisms is crucial for precise protection and restoration of the Beijing-Tianjin-Hebei ecosystem. We estimated the net ecosystem productivity （NEP） based on MODIS remote sensing data and explored the spatial and temporal patterns of carbon sequestration benefits and succession patterns in the Beijing-Tianjin-Hebei Region from 2002 to 2020 by using Sen's trend + MK test, Hurst index, and center of gravity shift and quantitatively separated the relative contributions of carbon sequestration benefits driven by human activities and climate change by using bias correlation, complex correlation, and residual analysis. The relative contributions of anthropogenic activities and climate change in driving the spatial and temporal changes in carbon sequestration were quantitatively separated using partial correlation and residual analysis. The results showed that： ① NEP in the Beijing-Tianjin-Hebei Region showed an increasing trend year by year over the past 20 years, with a growth rate （in terms of C） of 3.066 4 g·（m
