One of the characteristics of complex systems is their emergence. Samen district, as part of the central area of Mashhad, has been affected by the various urban development plans. The purpose of the current research is to identify the evolution of the effects of the renovation and improvement plans of Samen district, focusing on the role of the emergence of space in the occurrence of theft crimes. In this regard, by using the comparative-historical method, the evolution of the area has been investigated in recent years, and the effect of the layout of the area on committing theft in two time periods before and after the plans has been investigated. Documentary- and library-based studies are considered as the most important data collection tools in the current research. The data of geographic information system was used to measure the emergence of theft, and the data taken from Khorasan Razavi Police Office was used to check the amount of theft. For data analysis, depth map and Arcpro software have been used. The results of the research show an increase in integration in the new area, so that the permeability of the whole district has increased. This increase in integration has caused the distribution of thefts to be extended into neighborhoods, while in the old area, theft crimes mainly occurred in the main streets. Therefore, it can be stated that the changes that have occurred in the area have caused the appearance of "Inviting rather than Uninviting"characteristics.
