[Objective] The aims of this study are to assess the amount of change in ecosystem service value(ESV)under the combined effect of the dual processes of urbanization and ecological restoration, to reveal the impact of urbanization and ecological construction on ESV in the Beijing-Tianjin-Hebei urban agglomeration, and then to provide theoretical references for decision-making on coordinated regional development and sustainable development. [Methods] This study takes the Beijing-Tianjin-Hebei urban agglomeration as the study area, identifies regional urban expansion and ecological construction information based on land use/cover and socioeconomic statistics from 1995 to 2020. We also combine the ecosystem service unit area value equivalent factor method, spatial autocorrelation and cold hotspot analysis to develop a study on the impact of the dual process of urbanization and ecological construction on regional ESV at spatial and temporal scales. [Results](1)The ESV of the Beijing-Tianjin-Hebei urban agglomeration generally declined from 1995 to 2020, showing a trend of first decline and then increase, and the ecological environment improved significantly from 2015 to 2020.(2)The occupation of other land types by urban construction land caused by urban expansion was the main factor that made ESV decrease, which made regional ESV decrease by 36.82 billion yuan; ecological construction made regional ESV increase by 22.567 billion yuan. [Conclusion] The increase in ESV due to ecological construction was not enough to offset the decrease due to urbanization. The regions with stronger impact of urbanization and ecological construction on ESV are mainly located in the western and northeastern parts of the urban agglomeration, and the regions with weaker impact on ESV are mainly located in the southeastern part of the urban agglomeration.
