Summary: In this study; for the 26 regions included in the IBBS Level 2 classification, the validity of the interregional income proximity hypothesis and the effects of interregional inflation proximity on it; using the annual data of the 2004-2016 period, with the help of 22 different models, the absolute beta proximity, the conditional beta proximity, the sigma proximity and the variation rate approaches were analyzed. The stagnation of the series; LLC, IPS and Hadri panel units were tested with root tests and the series were found to be I(1) . The presence of causality relationships between the series; Granger and Dumitrescu and Hurlin panel have been studied by causality tests. The existence of the matching relationship between the series included in the Models has been tested by the Kao panel matching test. The combination rates in the models are predicted by the PDOLS method. In the analysis of income proximity; in the period 2004-2016 in Turkey the absolute income proximity hypothesis is not valid, and the conditional income proximity hypothesis is valid. It has been found that the regions are located in the west of the country and that inflation increases the national income per person and the proximity between the regions, and that their public spending has an immense or negative impact. The employment in the agricultural sector and the income obtained from this sector has affected economic growth and inter-regional income proximity, and the services and industrial sectors have a positive contribution to this sector. External trade, the training of the labour force and the number of qualified healthcare staff have a positive impact on the country’s per capita income and the inter-regional income approach, while climate change has been found to be harmful in this area. According to the sigma proximity and variation ratio approaches made for income, it was also seen that in the period 2004-2016 in Turkey there was the proximity of income between regions.
