Abstract：Municipal solid waste (MSW) is an environmental problem that needs to be solved urgently. Controlling the generation of MSW and reducing the environmental hazards caused by MSW are relevant to the construction of ecological civilization. Based on the data of 258 prefecture-level cities in China in 2003 and 2017， the characteristics of the spatio-temporal changes of MSW generation in China are analyzed.And then using ordinary least square model (OLS) and geographically weighted regression model (GWR) the impact of economy， population size， urbanization level and industrial structure on the generation of MSW are studied， and the two models are compared. The results of the study show as follows.First， except for the Northeast China region， the MSW generation of other regions' cities have greatly increased， and the East China region's cities are the most obvious. And the more economically developed the cities with the larger the population， the stronger the growth trend of MSW generation. Second， the regression results of OLS model suggests that the promotion effect of economy， urban population size， urbanization level and industrial structure on the generation of MSW is enhanced， and urban population size is the most important factor to promote MSW generation， followed by industrial structure， urbanization level， economic development. Third， GWR model is superior to OLS model in explaining the influencing factors of MSW generation， and the regression results of GWR model indicate that the influence of various factors on MSW generation has significant spatial differences and changes over time. According to the research results and the current economic and social development status of each city， specific suggestions are put forward for each city to control the growth of MSW generation.
