ABSTRACTThe research of economic spatial difference has always been one of the core issues in thestudy of regional economics and development economics,and it is also a universal problem inthe process of economic development in the world.It has been widely concerned by academiccircles and government decision-making departments in various countries.As one of the centralcities of Fujian's economic development,Quanzhou's in-depth analysis of the evolution ofregional economic disparities and its causes has important theoretical and practical significancefor exploring the coordinated development of regional economy.Based on the summary of previous studies,a series of quantitative indicators were appliedto study the spatial difference and evolution of Quanzhou's economy in 2011-2017 years basedon GIS and spatial statistical analysis.Based on the global and local spatial autocorrelationanalysis of ESDA,with the support of GIS software and GeoDA spatial statistical software,wemake an empirical analysis of the overall and local spatial differences of economic spatialdifferences based on the per capita GDP data of counties in Quanzhou in the past 2011-2017years.First points out the research contents and objectives,summarized the economic spatialdifference of relevant research results,research progress of the difference of the domestic andinternational economic space carried out;and expounds the theoretical basis and researchtechnical route and data source software combined with the method and the conclusion of thetechnology to achieve ESDA expression by GIS and statistics the calculation of Quanzhou citysince 2011;and the difference of regional economy spatial patterns were analyzed by empiricalresearch,and expounds the ideas and Countermeasures for the coordinated development ofregional economy in Quanzhou city;the final conclusion is as follows:(1)through the calculation of the relative development rate of cities in 2000-2006 years,theresults vary greatly,and the highest rate of relative development in Jinjiang is 9 times the lowestin Dehua.It shows that the economic development of each county and city in Quanzhou is
