Abstract: Industrial land supply is an important embodiment of the industrialization process and industrial economic development. Analyzing the temporal and spatial characteristics of industrial land supply scale is conducive to promoting the structural reform of land supply side, promoting high-quality industrial development and optimizing the spatial pattern of land. Based on the announcement data of industrial land supply in Chongqing from 2009 to 2018, the industrial land supply database of Chongqing was established, and the temporal and spatial variation law of industrial land supply scale in Chongqing was analyzed by locational Gini index, kernel density distribution, hot spot analysis and trend analysis. The results show that: (1) From 2009 to 2018, the supply scale of industrial land in Chongqing was in a general trend of fluctuation and decline, and the districts and counties with large supply scale concentrated in the main urban area of Chongqing and the western area of Chongqing. The supply location showed a more obvious distribution in the direction of northeast to southwest. The locational Gini index has the characteristics of volatility, and the spatial distributions are unbalanced and balanced repeatedly. (2) The scale of industrial land supply points presents the spatial layout pattern of “main ring-dot”, and the main ring presents the inner and outer core density change circle layer of “median value-secondary high value-high value”. The high-density core gradually gathered to the center of the main urban area, which is closely related to the establishment of Chongqing Liang Jiang New Area, the establishment or upgrading of industrial parks, and the development of resource-based industries. The hot spot areas of supply scale change in the east and west sides of the main urban area, and the cold spot areas are concentrated in the northeast corner of Chongqing. (3) The central urban area of Chongqing and its western and southern regions had the advantages of large industrial land supply scale, which was consistent with the changes of industrial economic development of Chongqing and the development layout of the city, and have laid a good foundation for the construction of Chengdu-Chongqing city economic circle.
