The automobile industry has always been the focus of various government policies due to its Extensive backward and forward linkages in economy. Undoubtedly, the quality of policy and the effectiveness of laws and regulations play a fundamental role in shaping the growth of this industry. Therefore, in this article, in the period of 1368-1401, the regulation in the automobile industry has been studied. The results show that more than 260 laws have been enacted in this industry. Among the most important of these laws, “car imports and its parts” had the highest share with 80 cases (about 31%). Pricing with 46 laws (18 percent) and “vehicle technical and environmental standards” with 41 laws (about 16 percent) are in the next ranks. On the other hand, the Council of Ministers has enacted the most legislation in the automotive industry with 109 laws (42 percent). The Ministry of Industry, Mining and Trade with 50 cases (19 percent) and the Competition Council with 40 cases (15 percent) are in the next ranks of legislative institutons in the automobile industry. The number of laws enacted in this period and especially since 2017 shows that the government has made great efforts to regulate the industry and the automobile market. In this way, more than 62% of the enacted laws belong to the period 1397-1401. But the high gap between the factory price and the market price, the incompatibility of the price with the quality, is one of the most important signs of ineffective regulation.
