摘要：According to Huntington, quantitative growth and qualitative change of a new middle class lead to the development of civil institutions and the decline of authoritarian symbols, and majority for political changes are supported. The question is that why the process of political changes has not been materialized in spite of this class increase in Saudi Arabia and Iraq? Based on the theory of transition to democracy and the comparative method, findings show that both countries are similar in increasing symbolic features of emerged middle classes, such as the development of higher education, bureaucracy and per capita income. However, due to cultural barriers, the rentier nature of the government, the patronage relationship, and the negative role of the external factor, any role in advancing democratization is excluded from this class, and tactical liberalization from above may lead to revolutionary change if democratic demands are not met, and may cause a general uprising. Political instability and structures imposed by American after the collapse of the Baathist regime are also responsible for dysfunction of this classes in Iraq in the establishment of democracy while Iraq has passed the first process of democratization by the collapse regime of Saddam and entered the second phase of democratic institutional consolidation, yet Saudi Arabia has faced serious barriers in her first phase.
