The effect of management ability on the increase of investment in intellectual capital in companies listed on the Tehran Stock Exchange, emphasizing the role of the CEO's job concern

The management's ability to use resources, through creating a sustainable competitive advantage, is a factor in increasing intellectual capital and, as a result, increasing the value of the company, and capable managers have more motivation to invest more favorably in intellectual assets, which can also improve the company's performance. The purpose of this research is to investigate the effect of management ability on the increase of investment in intellectual capital according to the life cycle of companies listed on the Tehran Stock Exchange. The current research is applied in terms of purpose, and in terms of methodology, it is descriptive of causal (post-event) correlation. To test the hypotheses of the research, 149 companies were selected from 2012 to 2021 using the systematic elimination sampling method from among all the companies admitted to the Tehran Stock Exchange. To test the hypotheses of this research and determine the relationship between independent and dependent variables, econometric models have been used and the relevant hypotheses have been investigated using the panel multivariate regression method. The findings of the research show that management ability increases intellectual capital. Also, the CEO's job concern (the CEO's lack of influence) increases the positive effect between management ability and intellectual capital. Contrary to that, the job concern of the CEO (the decline stage of the company in the life cycle) does not have a significant effect on the relationship between management ability and the increase of intellectual capital.
