Abstarct: This study examines the impact of potential threshold Advertising on the value added of Indutries of Iran, in variants with Investment, Sales, Export and Reaserch & Development spending during the years 1374-1392. Is deals. For this purpose, the panel smooth transition regression model (PSTR) which was very convenient for heterogeneous panel data analysis, is used. The population of this study includes 90 industries. which has a 4-digit ISIC codes to census Workshops for 10 workers in the industries of Iran during the period 1374-1392 is. In this study, the three elements defined market, the market investigated and behavioral indicators such as the advertising market is explained. The Schools of Thought in relation to the structure-conduct-performance paradigm is presented.

In some of these studies is positive relationship between advertising and profitability and in some studies has been negative and some other nonsense. The experimental results obtained in this study rejects the hypothesis of linearity, proposes a two-regime model size threshold to 0.84 advertisement. In the first regime, the cost of advertising, investment, research and development costs is positive and the effect of the sale on value added is positive and statistically significant. in the second regime and after passing through low-level Advertising to higher rates The effect advertisin of valu added is still positive and significant and increase its influence. Impact sale on value added is positive and significant, too. The impact of investment and R&D on value added is positive and significant but reduced the severity of its impact on the value added. The impact export on value added in both rezhim was almost zero and statistically meaningless.
