Therefore, to study the development of each sector, it is necessary to consider its various dimensions. On the other hand, in order to accurately plan and effectively implement policies, it is necessary to pay attention to its evaluation at the partial and provincial levels, instead of examining the extent of development in general and at the national level. Therefore، This paper used numerical taxonomy and SPSS and Excel softwares to evaluate the degree of development of the provinces of Iran. It also examined the existence of a core-periphery model to determine the process of inequality change between central and border provinces with the help of 25 indexes for the years 2006, 2011 and 2016. Results confirmed the model of the core-periphery; central provinces such as Tehran, Isfahan, Yazd have had the highest level of development and border provinces such as Sistan Baluchestan, Hormozgan, and Kurdistan were at a low level of development. Also, considering the inequality index, inequality between central provinces was more than the inequality between border provinces. In addition, during the years 2006 to 2016, the level of development and inequality in the provinces of the country had been decreasing.
