## 3 Methodology and Database
The alpha-numeric database obtained in the form of an.xls file from listafirme.ro for Cluj-Napoca, and the KRTK Databank for Pecs, provide, on the one hand, information related to the spatial location of creative industries (street and number, county, country, and city) and information used in the geolocation process, and, on the other hand, information related to the CAEN/NACE code and field of activity for each individual location. The first part of the information was used to geolocate the creative industries and obtain point vector databases using the geolocation services provided by ESRI for each individual record. The second part of the information is constituted as an attribute database used in the qualitative spatial analysis of grouping creative industries according to their specifics. The spatial analysis stage foregrounds the management and integration of spatial databases (communication paths and spatial location of creative industries) on a logical basis, using mathematical integration formulas for the spatial representation of the main categories of creative industries and using time analysis and modelling of access related to the location of the creative industries. This is in order to highlight the areas with high and low accessibility, which can later be analysed comparatively for the two territorial administrative units taken into account. The first part of the spatial analysis is dedicated to obtaining the main categories of creative industries, starting from the grouping of unitary creative industries according to the specifics of the activity, taking into account the CAEN/NACE code and their field of activity. The study uses the NACE code delimitation for cultural and creative industries [39]. Thus, using the geocoded vector database and the spatial analysis on the attribute table, from a total of 4839 companies for the city of Cluj-Napoca and 1308 companies for Pecs, 11 classes with unique characteristics were used in the process of spatial accessibility modelling and the comparison of the two main urban centres. The identification of the territorial accessibility related to the locations of the classes representing creative industries for the two main urban centres is carried out on the basis of the network analysis, considering the service area module made available by the ArcGis 10.8 geoinformational software. Accessibility analysed in terms of the time needed to access the creative industries is based on the identification of standard time intervals. As part of the analysis, five temporal intervals were chosen to meet the urban planning requirements in force. Thus, the time intervals 0-5 min, 5-15 min, 15-30 min, 30-60 min and more than 60 min on foot were chosen. Considering the fact that the concept of the 15 min city (developed by [PERSON] in 1920) [40], which is still relevant today, was proposed for implementation at the Climate Change Conference (COP 21) in Paris, 2015 [41; 42; 43], the 5-15 min interval was used in the analysis. The 0-5 min analysis is based on the 5 min city concept being implemented in Copenhagen to highlight the socially, architecturally and sustainably designed developed city, a city with ideal urban development. The other two intervals--30-60 and more than 60 min--were implemented in the accessibility analysis due to the large spatial extension of the two cities and the concentration of the creative industries (for the most part) in the central areas, thus highlighting the areas with accessibility reduced from the periphery of the main functional areas. The analysis of accessibility obtained for the five categories can be carried out in the current stage of unitary spatial analysis for each class of creative industry and at the level of each administrative unit analysed, but it is not possible to make a direct comparison between the two urban centres analysed due to the spatial scale of different representation.
