Research on the manifestations, causes and suggestions of regional economic development differences has always been an important part of regional economic disciplines. As one of the largest and fastest economic growth provinces in China, the difference of economic development level and the evolution of spatial pattern among different regions in Guangdong Province attract the attention. Taking county unit as the research sample can better reflect the fine characteristics of spatial difference of economic development level. Based on the per capita GDP of each county unit in Guangdong Province from 1998 to 2016, this paper uses the global Moran’s I to judge whether there are agglomeration characteristics of county economic disparities in Guangdong Province, to describe the agglomeration state and spatial distribution characteristics of county economic disparities in Guangdong Province by Getis-OrdGi*, and to reveal the location, distribution and evolution of economic disparity agglomeration in Guangdong Province by standard deviation ellipse. The results show the development disparity of county economy in Guangdong province presents an evolution process that first expands and shrinks later, with the year of 2004 is an important time node; after 2005, the level of economic development in the Pearl River Delta region is still very high, but the economic growth rate has slowed down compared with other regions, and it is in the last level; the regions at the first level mainly concentrate on some counties and districts such as Zhanjiang, Shaoguan, Huizhou and Jieyang; there is a positive spatial correlation between the economic development levels of county units in Guangdong Province, which has obvious clustering characteristics. Before 2004, the degree of economic agglomeration increased, and the degree of economic agglomeration gradually decreased after 2004. During the investigation period, the spatial range of hot spots changed slightly, mainly covering the Pearl River Delta and its adjacent peripheral areas. The spatial range of cold spots changed greatly, but mainly concentrated in eastern Guangdong. The standard deviation ellipse of county economy in Guangdong Province was mainly in the northeast-southwest direction. After 2005, the rotation angle gradually decreased, showing a counterclockwise rotation to the west and north. The relative speed of the economic development level in western and northern Guangdong increased, and the disparity of the economic development level of each county unit was alleviated. Finally, some suggestions are put forward for the differences of county economic development in Guangdong Province. The spatial structure of regional economy is an effective way to adjust the disparity of county economic development in Guangdong Province. The government should formulate targeted support policies for different county economic developments. Measures should be taken to promote the full mobility of various elements in space and industrial gradient cooperation in different regions of Guangdong Province.
