In the present study, while gathering the library data and using the existing information in the industrial companies of Semnan and Tehran provinces the informational layers were prepared using GIS software. Also, in order to analyze the industrial towns of Abbas Abad, Eyvanekey, Garmsar and Semnan with emphasis on the attraction of applicants and investment, the layers required in the form of GIS software were prepared. By analyzing the output of the data in the form of a map, it was determined that the number of parts delivered in Abbas Abad industrial town was about 1.39 times the total of the three settlements, i. e., Eyvanekey, Garmsar and Semnan. However, in spite of the distance of 12, 40 and 150 km of Abbas industrial town in the industrial towns of Eyvanekey, Garmsar and Semnan, the number of units in operation in the industrial town of Abbas Abad was 1.82 times, the employment rate is 1.37 times and the amount of investments made is 1.11 times the total of the three industrial towns.The fact that Abbas Abad industrial town in Tehran as the capital of the country accounts for more than 50 percent of the financial resources and 45 percent of the industries and 17.5 percent of the total population of the country, can be considered as one of the main factors for this difference.
