Spatio-temporal Pattern of Green Land Use Efficiency in Beijing-Tianjin-Hebei and Its Influencing Factors

Abstract

[Objective] This paper explores the spatial-temporal pattern and influencing factors of green land use efficiency in Beijing-Tianjin-Hebei, and provides theoretical reference for promoting the green development and transformation of land use and optimizing the spatial development and protection pattern of land. [Methods] Taking Beijing-Tianjin-Hebei as the research area, we constructed a land green utilization efficiency evaluation index system, used the SBM-DEA model and exploratory spatial data analysis (ESDA) to reveal the characteristics of spatial and temporal patterns of land green utilization efficiency in Beijing-Tianjin-Hebei, and explored the influencing factors by using the Tobit multiple regression model. [Results] (1) Since 2008, the overall green land use efficiency in Beijing-Tianjin-Hebei has been on the rise, especially since 2012, which has reached an effective state. (2) The spatial non-equilibrium characteristics of “high in the middle and low in the surroundings” are shown in the space, with Beijing and Tianjin in the high-efficiency centers, and the positive spatial correlation in the whole area is significant and increasing, the local spatial agglomeration characteristics are obvious, and the efficiency value correlation characteristics among the neighboring cities are significant. (3) Economic development and ecological governance have a significant positive impact on the improvement of land green use efficiency, with the level of economic development having the most prominent impact, while land urbanization and population agglomeration reflect a significant negative impact. [Conclusion] It should accelerate the promotion of the green development transition in Beijing-Tianjin-Hebei, further deepen the Beijing-Tianjin-Hebei synergistic development, and focus on improving the level of economic development in inefficient regions. It is recommended that the optimization of the spatial development and protection pattern of land be strengthened, a strict land-use system be implemented, the restoration and maintenance of land ecosystems be strengthened, and initiatives to improve the efficiency of the green use of land be formulated in a differentiated manner, so as to comprehensively promote the improvement of the efficiency of green land use.
