Capacity of Islamic Teachings in Establishing Different Parts of Economy (With the focus on cooperative sector)

After failure of private sector in poverty reduction, capitalism functioned a major role in economy. The mixed and two-part economy has also been unsuccessful in economic problems, because capitalists dominated all the parts of government and acted on behalf of their own benefits. After demonstrating economic problems as lacking ethical teachings, economies followed the non-profit economy, but it could not solve the problems. Therefore, some authorities suggested the cooperative economy as the solution, but the problems became bitter.The author believes that for solving economic problem, there should be a four part economy. The capitalism teachings have not the enough capacity for this kind of economy and instead the Islamic economy teachings have this capacity. This research with a descriptive-analytical approach and comparing the capacities of Islamic teachings and capitalism teachings, establishes a four part economy according to Islamic teachings.
