چکیده
امروزه اهمیت آب و مدیریت منابع آن ازجمله موضوعات بحث انگیز در سطح جهانی به دلیل تغییرات آب و هوایی است. این موضوع خصوصاً در کشور ایران که از خشک سالی مستمر رنج می برد با اهمیت تر می باشد. از همین رو هدف پژوهش حاضر، تبیین عوامل مؤثر بر گزارشگری آب در شرکت های پذیرفته شده در بورس اوراق بهادار تهران است. برای این منظور با استفاده از داده های 102 شرکت طی سال های 1391 الی 1400 (1020 سال-شرکت) که به روش حذفی انتخاب شدند، عوامل مؤثر بر افشای گزارشگری آب تعیین و با روش رگرسیون گام به گام و رگرسیون چندگانه مورد تجزیه وتحلیل قرار گرفت. نتایج این پژوهش نشان داد که بیشترین میزان افشا مربوط به آب متعلق به شرکت های صنعت شیمیایی و نفتی بوده، همچنین در بررسی عوامل مؤثر بر گزارشگری آب مشخص شد که عوامل سن شرکت، اندازه هیئت مدیره، تخصص مالی کمیته حسابرسی، تمرکز مالکیت، مالکیت نهادی، بازده دارایی، میانگین بارش سالانه، شهرت، قوانین و حساسیت صنعت به آب بر گزارشگری آب شرکت ها تأثیرگذار بوده اند، این یافته ها می تواند برای برنامه ریزی و کنترل در خصوص مدیریت آب و همچنین شناخت سرمایه گذاران از محرک های افشای شرکتی در تشکیل پرتفوی بهینه شان مفید باشد.Drivers of Corporate Water Reporting
Nowadays, the importance of water and the management of its resources are among the most controversial issues at the global level due to climate change. This issue is especially important in Iran, which suffers from continuous drought. Therefore, the current research aims to explain the determinants affecting water reporting in the listed companies on the Tehran Stock Exchange. For this purpose, by using the data of 102 companies during the years 2012 to 2021 which were selected by elimination method, the determinants affecting the disclosure of water reporting were identified and analyzed using stepwise regression and multiple regression methods. The results of this research showed that the highest amount of disclosure related to water belonged to chemical and oil industry companies, Additionally, in the investigation of the determinants affecting water reporting, it was found that the determinants affecting water reporting, it was found that the determinants of firm age, board size, financial expertise of the audit committee, concentration of ownership, institutional ownership, return on assets, average annual rainfall, reputation, regulation, and sensitivity of the industry to water had an impact on corporate water reporting. These findings can be useful for planning and controlling water management, as well as for investors to know the drivers of corporate disclosure in forming their optimal portfolio. Introduction Nowadays, the importance of water and the management of its resources are among the most controversial issues at the global level due to climate change. This issue is especially important in Iran, which suffers from continuous drought. Therefore, the current research aims to explain the determinants affecting water reporting in the listed companies on the Tehran Stock Exchange. Research Question(s): What are the determinants influencing the disclosure of water reporting in Tehran Stock Exchange member companies? What is the impact of these determinants on the disclosure of water reporting? Literature Review Although the limitation of water resources and its serious role in sustainable life and economic activities are not hidden from anyone, with increasing concerns about water and its pollution, and the effects of climate change, how to effectively manage water and report it at the corporate level has become more important. This attention has been such that today the disclosure of water management information and its risks has become part of the strategy and sustainability efforts of companies. Water reporting at the company level is a tool for transferring information about water risks, the effects of risk, and the company's water resources strategy. Multiple theoretical frameworks can be used to justify the necessity of water reporting at the company level and its determinants. These theories are in the same direction and complement each other, such that they are competing theories because all of them are trying to explain corporate water reporting. These theories include legitimacy theory, stakeholders theory, social responsibility theory, and resource-based theory. Methodology The population studied in this research comprises the companies that are members of the Tehran Stock Exchange over a period of 10 years from 2012 to 2021, and ultimately, 102 companies (1020 company-years) were selected using the systematic elimination method. The method used in this research to explain the determinants affecting the disclosure of water reporting included five steps: In the first step, the study of literature related to water reporting and the determinants affecting it was conducted. In the second step, a comprehensive review of the literature was carried out by referring to Springer, Wiley, Science Direct, Google Scholar, and ResearchGate databases. The preliminary search identified a number of articles that focused on broad areas of disclosure. The process of studying the abstracts and introductions of the articles led to the exclusion of some out-of-scope studies. After filtering the results, only eight of these articles related to water disclosure were selected. In the third step, a questionnaire was prepared and distributed among experts to confirm and complete the components. This step was used as a complementary method, according to the experts, to confirm and complete the determinants extracted from the literature, taking into account the local conditions of Iran. The fourth step involved finalizing the determinants after reviewing the questionnaires; finally, ten responses were received from the questionnaires sent to the experts, and the questionnaires were tested with the independent t-test method. The results showed that all the determinants included in the questionnaire, except for gender diversity, were approved by the board of directors and the audit committee. In the fifth step, the stepwise regression method was used to examine the effective variables and select the effective stimuli on water reporting, and then the multiple regression method was used to measure the impact of each of the approved stimuli. Results In the stepwise regression method, the dependent variable (water reporting disclosure) and independent variables (firm size, firm age, financial leverage, audit committee size, audit committee financial expertise, independent members of the audit committee, board size, ownership concentration, institutional ownership, government ownership, return on assets, corporate social responsibility, average annual rainfall, GDP growth, reputation, and sensitivity of the industry to water) were selected and, over 10 stages, various regressions were formed and finally, ten independent variables were confirmed. The adjusted coefficient of determination of this regression is equal to 0.322, which has the highest coefficient of determination compared to other models, and the value of the significance level of the model is equal to 0.000, which shows the significance of the model. Finally, in response to the research question of what are the drivers of water reporting in companies, the following variables can be mentioned: firm age, audit committee financial expertise, board size, ownership concentration, institutional ownership, return on assets, average annual precipitation, reputation, regulation, and industry sensitivity to water. Subsequently, to check the impact of each of the factors, the variables selected in the previous step were entered into the regression and analyzed with the multiple regression method. Finally, the regression equation was obtained as follows: WaterDisclosure= -3.327 – 0.620 LnAge + 0.764 BoardSize + 1.450 Concentration + 0.895 ROA + 0.119 Co-financial + 3.191 Reputation – 0.001 Rainy – 0.977 Regulation+ 1.450 Institutional + 0.162 Sensetive Discussion By reviewing the literature, it was found that several determinants were effective in water reporting in companies; some of these determinants were related to the structural characteristics of the company, some to the characteristics and ownership structure, and finally to the financial performance of the company. Also, determinants such as the existence of foreign regulation and supervision, the company's attention from major shareholders, and reputation, as well as the level of social responsibility of companies, can lead to more disclosure of water-related information. In this research, in addition to these determinants, some other determinants such as the country's economic growth, annual rainfall, and audit committee characteristics were investigated by interviewing experts. Conclusion According to the findings of the research, companies with higher profitability and reputation also have higher disclosure. In addition, the findings suggested that considering there is still no codified and general regulation for water management applicable to all companies in Iran, it is recommended, according to the theory of stakeholders, that legislators and the environmental organization establish specific and enforceable regulations for companies to adhere to and disclose information related to water in their reports. Furthermore, since there is currently a requirement for listed companies to prepare sustainable reporting, providing information on water and how to manage water and its risks can be combined with other information on social activities and governance. This integration of reports will enable better monitoring for policy-makers and foster collaboration among stakeholders for responsible water management and achieving sustainable goals at both the corporate and global levels.
