Green development is an important part of the construction of an ecological civilization system. From the five aspects of green economy, green innovation, green resource utilization, green environment, green life, etc., build an evaluation index system for the development level of Guangxi's green economy and conduct in-depth research in order to provide references for promoting the green development of Guangxi. The entropy method is used to calculate the comprehensive score and average score of Guangxi's green development level from 2009 to 2018, and the natural fracture method and local spatial autocorrelation are used to analyze the temporal and spatial differences of Guangxi's green economic development level. The results show that:The overall green development level of Guangxi cities from 2009 to 2018 shows an upward trend. In terms of spatial distribution, Guangxi's green economic development level presents a pattern of "low in the middle and high in the surrounding area". In general, the development level of Guangxi's green economy continues to improve, and the two indicators of green life and green utilization of resources have a greater impact on the level of green economy development.
