Special attention to the relative advantages of the economy is the best way toward economic development of the country. The chemical sector, due to the country's advantage, owing to its considerable natural oil and gas resources, high variety of products, technology and market, has a significant charm and scope for technological innovation and development. Nowadays, the country's political and economic status has created opportunities for chemicals, but Existing policies have merely increased scientific research articles and in practice it has not cause to technological innovation (Patent). The first step in the policies for this sector, understanding the factors that influence firms to technology innovation. Therefore, the purpose of this study is to analyze of factors affecting the management of technological innovation in the chemical industry to provide solutions. In this paper, the factors, were investigated by using verification factor analysis and structural equations. Then, the relative importance of each factor was determined based on the Fuzzy BWM method. The results of the present study indicated that, R&D ability, R&D efforts, Sustainable Profitability With the most votes and low-risk chemical synthesis, less chemical waste science and technology diplomacy were ranked last.

This study aimed to investigate the performance of diverse stock market indices on the Tehran Stock Exchange during two distinct phases: a boom from September 2022 to December 2022 and a recession from December 2022 to September 2022 in the foreign exchange market. The results of this study diverged from the anticipated outcomes and show that by using dynamic conditional beta and conditional Treynor ratio during the period of exchange rate boom, export-oriented companies such as metals and chemicals in the Tehran Stock Exchange did not perform better than non-export-oriented companies such as Insurance and medicine.

Holding companies collect funds from subsidiaries and allocate them to important areas (Internal Capital Market). Managers of holding companies have the ability to transfer funds between subsidiaries. Some specific orientations cause the non-optimal allocation of financial resources. One of the concerns of investors is investing in companies where transparency is fully implemented. Companies are trying to achieve this by implementing corporate governance mechanisms. In this research, using a systematic review method, the dimensions of corporate governance were extracted with the stakeholder theory approach. Finally, in order to examine the question of whether the managers of holding companies consider the interests of all stakeholders when using the internal capital market or not, according to the assumptions of the research, the dimensions of corporate governance on stakeholders have been investigated. To investigate this relationship, a set of questions based on Likert scale about the measured variables of the target society was designed. After data collection, finally, data analysis was done by statistical method using SPSS software and structural equations using SPLS software, and the results of path analysis and causal relationships between the research variables were interpreted in the conceptual model. The data analysis also showed that the value of the path coefficient, the effects of dimensions and components of corporate governance and stakeholders, is a positive value. The null hypothesis of the research is rejected and the opposite hypothesis is confirmed. This shows that there is a relationship between the effects of corporate governance dimensions and stakeholders. The direct effect value indicates a strong and high effect size. As a result, the interests of all stakeholders should be considered.
