The share of taxes to total public revenues differs among countries, and the main factors that have been discussed as the cause of the difference in the tax structure are the level of development of countries that are typically represented by gross domestic product per capita, productive expertise, or the structure of the economy; external factors such as the level of foreign direct investment and trade. The amount of public debt and public policies, including exchange rates, inflation and fiscal policies, government efficiency and organizational factors, such as political stability, accountability and transparency, civil and political rights, education levels, general expenses for education, etc, are also determinants of tax revenue. The purpose of this study was to investigate the effect of development indicators on the tax revenues of Iran during the period of 1979-2017 based on the Autoregressive Distributed Lag Model (ARDL) method. Based on the results of this study, the increase of per capita GDP in the country has a positive effect on the ratio of direct taxes to GDP, but has a negative and significant effect on the ratio of indirect tax to GDP. Also, the impact of the human development index on the ratio of direct taxes and indirect taxes to GDP is positive and significantand the effect of the index of inequality of income distribution, that is the Gini coefficient, on the ratio of direct taxes and indirect taxes to GDP, was negative and significant. Finally, the effect of the combined development index on the ratio of direct taxes to GDP as well as the ratio of indirect tax to GDP has been positive and significant. Also, the country's oil revenues have a negative and significant effect on the ratio of direct taxes and indirect taxes to GDP.

Regional inequality is a multidimensional phenomenon and includes different areas of economic, social and cultural. Therefore for any country is necessary to introduce a multidimensional composite index for the measurement of regional inequality. This study aimed to determine the level of regional inequality of Iranian provinces and to identify the main determinants of the inequality, to introduce a combined index for regional inequality measurement. To this end, this study has selected 25 indicators in 5 different dimensions (economic, knowledge and human capital, infrastructure, social-cultural and environmental) and it has collected data relating to the years 2001 and 2013. Also, by applying innovation, it has used two-step principal component analysis. The results show that regional disparities are declining in period under review. In this period, Provinces of Tehran, Yazd and Semnan have had the highest development level, respectively, and Sistan-Baluchistan province also has been fixed at the end place. The results showthat in provinces with higher development level. Economic and human capital indicators were main causes of inequalities in the regional development. Also high population density has forced the government to invest more in infrastructures, health and education in more developed provinces. On the other hand,having knowledge and investment spillovers is an effective factor in development of Tehran’s neighboring provinces.
