摘要：Given that most Islamic countries are including developing or less developed countries, face problems such as low levels of income and low rates of economic growth, these countries need rapid economic growth to get rid of such problems. And since Tourism as a highest earning industry in the world, it can play a significant role in the economic growth of countries, including Islamic countries. And considering that before the development of the tourism industry, the use of resources should be such that the resources that will enter this sector in the future will not be wasted and will be optimally allocated. Therefore, this study evaluates the tourism industry efficiency in OIC Countries using data envelopment analysis method in 2016. Also, input-oriented BCC and CCR were used to assess the performance of countries. The findings showed that 32% of the countries under review, based on the CCR model and 48% based on the BCC model, are efficient and the rest are inefficient. Also, using the Anderson-Peterson model (AP), the countries of the efficient were ranked according to the CCR model in Bahrain and based on the BCC model, Turkey ranked first, and finally the reference countries of the pattern of inefficient countries were introduced and suggested.
