## 3 Methodology and Database
The comparative analysis is based on the standardisation of the spatial analysis scale, involving comparing the spatial extension of each accessibility interval with the entire analysis surface of the analysed urban centre, based on the qualitative scoring technique. Thus, it was decided to credit each accessibility interval with values between 0 and 1 according to Table 1.  
The qualitative assessment used to standardise the scale of spatial analysis has as its main concept the fact that a larger area occupied by a certain accessibility interval compared to the entire study area has a greater impact on the territory. It takes values between the same limits of the interval for both urban centres analysed, thus allowing us to make real comparisons between the two. The calculation of the credit rating within the range, specific to each accessibility class, is performed using the formula proposed by [PERSON] et al., 2017 [PERSON] et al., 2017 [PERSON] et al. (2017). \[\text{(x $\times$ y)}/100=\text{z} \tag{1}\]  
\[\text{x $=$ Smax $-$ Smin} \tag{2}\]  
where  
x--the value of the scoring interval;  
y--the interval area of spatial extension, as percentage;  
z--the value of the accessibility scoring depending on the area;  
Smax, Smin--the maximal value of the scoring interval, the minimal value of the scoring interval. \[\text{sv}=\text{a}+\text{z} \tag{3}\]  
where  
sv--the scoring value;  
a--the basic value of the scoring interval;  
z--the value of the accessibility scoring depending on the area. The unitary comparative analysis of each class of creative industry can be conducted taking into account the variation of the results in the rating range specific to the accessibility class. The higher the rated value is in the range, the greater the influence of the range-specific accessibility class in the territory, thus having a significant spatial impact. Obtaining credit values for each accessibility interval and class of creative industry offers the possibility of integrating them to identify the general accessibility of the territory influenced by the 11 classes. The identification of general accessibility is based on the concept of the importance of the class in terms of the creative industry it represents. Due to the fact that, together \begin{table}

Table 1: Rating classes/accessibility intervals. with the qualitative rating, the working scale was standardised and the characteristic rating intervals were established for each accessibility class at the same time, the integration of the obtained databases is performed on the basis of the empirical equation that provides the normalisation of the scoring values (formula 4) [10; 44; 45; 46], so they fall within the general scoring interval (0-1) and can be comparatively analysed later using the scoring intervals employed (Table 1). \[\text{ACCES}=\sqrt{\frac{\text{R\&D}\times\text{ENG}}{9}\times(\text{ART}+ \text{CER}+\text{FLM}+\text{JEL}+\text{MED}+\text{PRN}+\text{RTV}+\text{REC}+ \text{SPT})}\]
