Nowadays, there is a growing attention on export activities and they are considered as a good strategy for companies to grow from supportive domestic sales to foreign developing markets, while offering greater flexibility, cost, and lowering different risks compared to other external development methods. With the internationalization of the global economy, the focus has been on improving export performance, which reflects the company's success in the economic field. An important point about Iran's exports, which should not be overlooked, is the decline on the reliance of the national economy on revenues from oil exports and the achievement of economic independence. Therefore, support for the export industries, especially non-oil exports, is one of Iranian priorities for increasing economic growth and creating foreign exchange earnings. In the meantime, the economic performance of pharmaceutical companies is very important because the growth and development of this sector and the export of these products bring significant foreign exchange earnings. This paper focuses on the data gathered from the managers and exporters of the pharmaceutical companies and using some statistical tests to determine the effective components on export promotion. The study considers 18 factors and extracts five important factors including profitability and economic growth, developmental quality, encouragement and financial performance. The study also uses analytical hierarchy process (AHP) and DEMATEL techniques to rank these factors and their sub-components. Quality is considered as the most important factor according to the implementation of AHP and profitability and economic growth are determined to be the most influencing factors according to DEMATEL.
