Objective: To investigate the gravity center and spatial clustering of silicosis in Zhejiang Province, so as to provide the reference for improving silicosis prevention and control measures. Methods: Data on cases of silicosis in Zhejiang Province from 2013 to 2022 was collected from the National Occupational Disease and Health Risk Factors Monitoring Information System. The spatial and temporal characteristics of silicosis incidence in Zhejiang Province were analyzed using the gravity center migration and spatial autocorrelation analysis. Results: Totally 2 902 silicosis cases were reported in Zhejiang Province from 2013 to 2022. The reported cases in 2013, 2019 and 2014 ranked the top three, with 545 (18.78%), 373 (12.85%) and 372 (12.82%) cases, respectively. The silicosis cases were predominantly males, accounting for 99.04% (2 874 cases). The main occupation was mining and related industries, accounting for 50.41% (1 463 cases). Gravity migration analysis showed that the gravity center of silicosis incidence was in Shengzhou City in 2013; from 2014 to 2018, it migrated to the southwest, and was located in Dongyang City and Yiwu City; from 2019 to 2020, it migrated to the southeast, and was located in Xianju County and Tiantai County; then from 2021 to 2022, it migrated to the west, and was located in Pan'an County and Xianju County. Spatial autocorrelation analysis showed that there was spatial correlation of silicosis incidence in 2014, 2016, and 2021 (all Moran's I >0, all P<0.05). Ningbo City, Quzhou City, Wenzhou City and Taizhou City were high-high clustering sites. Conclusions The gravity center of silicosis incidence in Zhejiang Province from 2013 to 2022 had a slight migration, and mainly gathered in the central regions.
