Abstract: [Objectives] Comprehensive land productivity can reflect the comprehensive utilization of land and the overall output level, which is the most basic and commonly used indicator in assessing land use efficiency. This thesis aims to analyze the spatial and temporal changes of comprehensive land productivity in Chongqing from 1997 to 2023 in order to assess its land use efficiency.[Methods] This study measured the comprehensive land productivity of Chongqing Municipality, the only municipality directly under the central government in the western part of China, over the past 26 years (1997-2023) through relevant surveys and statistical data, and analyzed in depth the comprehensive land productivity of the 38 districts and counties under the jurisdiction of Chongqing, as well as the functional sub-districts of the "one district and two clusters" and the "one district and two clusters" in Chongqing. It also analyzes the characteristics of spatial and temporal differences in land productivity in 38 districts and counties under the jurisdiction of Chongqing and "one district and two clusters".[Results] The results of the study show that over the past 26 years, the comprehensive land productivity of Chongqing has shown an annual growth trend, and the comprehensive land productivity of the 38 districts and counties and the functional subregions of "one district and two clusters" has also increased significantly, but the average annual growth rate of the comprehensive land productivity varies among different regions. From the perspective of spatial differences, there are significant differences in land productivity among the 38 districts and counties of Chongqing and the functional subregions of "one district and two clusters", which are mainly due to the different natural conditions, economic development levels and functional positioning of each region.[Conclusions] Based on the results of the study and the actual situation of Chongqing, this paper puts forward the leading measures to improve the comprehensive land productivity, with a view to providing a reference basis for Chongqing to improve the efficiency of land use and promote the sustainable use of land resources.
