بررسی تأثیر پدیده شکست ساختاری بر ارتباط ارزشی اطلاعات حسابداری چکیده هدف: هدف اصلی پژوهش حاضر بررسی تأثیر پدیده شکست ساختاری بر ارتباط ارزشی اطلاعات حسابداری است. روش: پژوهش حاضر به دلیل استفاده همزمان از متغیرهای مالی، حسابداری و اقتصادی و نیز استفاده از اطلاعات تاریخی شرکتها از نوع تحقیقات شبه تجربی از نوع پس رویدادی و میانرشتهای است. یافتهها: یافتههای پژوهش وجود سه شکست ساختاری معتبر را در دوره زمانی پژوهش نشان میدهند؛ بنابراین بازار سرمایه ایران در سالهای 1391 و 1392 و 1397 دچار شکست ساختاری شده است. ارتباط ارزشی اطلاعات حسابداری بدون لحاظ پدیده شکست ساختاری 16 درصد و در حالت با لحاظ پدیده شکست ساختاری 37 درصد است. نتیجهگیری: مطابق نتایج پژوهش شکست ساختاری در بازار سرمایه اتفاق افتاده است و با توجه به افزایش توان توضیحی الگوهای برازشی مبتنی بر اعمال شکست ساختاری به بیش از دو برابر میزان اولیه آن، میتوان پذیرفت که ارتباط ارزشی اطلاعات حسابداری تحت تأثیر پدیده شکست ساختاری قرار میگیرد؛ بنابراین در صورت عدم توجه به پدیده شکست ساختاری مدلهای خطی با پارامترهای ثابت نمیتوانند رفتار متغیرهای حسابداری را بهخوبی توضیح داده و تبیین کنند و الگوی برازشی مناسبی نیستند. همچنین به دلیل اینکه الگوها در صورت لحاظ کردن پدیده شکستهای ساختاری عملکرد متفاوتی را از خود نشان میدهند صرف توجه تنها به متغیرهای حسابداری در بررسی ارتباط ارزشی اطلاعات حسابداری بدون در نظر گرفتن رویدادهای شکست ساختاری سادهانگاری مسئله بوده و تأثیر نامساعد بر تفسیر استفادهکنندگان از اطلاعات حسابداری در جهت پیشبینی نتایج فعالیتهای اقتصادی آتی شرکتها میگذارد. | ||

Investigating the Effect of the Phenomenon of Structural Failure on the Value Relevance of Accounting Information Abstract Objective: the purpose of the present research was to investigate the effect of the phenomenon of structural failure on the value relevance of accounting information. Methods: the research was a quasi-experimental, post-event and interdisciplinary research due to the simultaneous use of financial, economic and accounting variables as well as the use of historical information of companies. According to the type of research, various econometric methods such as multiple regression analysis with panel data econometric method, endogenous calculation of structural failures and Wong's z test to determine the difference between the coefficients of the models were used. To measure and calculate the structural failure, the endogenous structural failure model proposed by Bay and Peron, and to measure the value relevance of accounting information, the two variables of profit and book value in both price and return models were used. Results: the findings of the research showed the existence of three valid structural failures in the research period, so the Iranian capital market had suffered from a structural failure in the years 2011, 2012 and 2017. It was also observed that when structural failure had occured, the value relevance of accounting information had decreased. The value relevance of accounting information without considering the phenomenon of structural failure was 16% and in the case of taking into account the phenomenon of structural failure was 37%; therefore, the value relevance of accounting information was affected by the phenomenon of structural failure. Moreover, the results of the research showed that due to the difference in the coefficients of determining the fitting patterns, the price pattern had more explanatory power than the return pattern in case of structural failure. Conclusion: according to the results of the research, structural failure had occurred in the capital market; therefore, if the phenomenon of structural failure was not paid attention to, linear models with fixed parameters could not explain the behavior of accounting variables well, and they were not suitable fitting models. Hence, failure-based models could include the effects of structural failure and provide a good explanation for the value relevance of accounting information. The increase in the explanatory power of the fitting models to more than double the initial amount based on the application of the phenomenon of structural failure showed that the value relevance of accounting information was different in two situations without considering the phenomenon of structural failure; therefore, the value relevance of accounting information was affected by the phenomenon of structural failure. The reason for paying attention to the phenomenon of structural failure was that the obtained results were more real and reliable and different from the case where structural failure was not considered. It was also observed that when a structural failure had occurred, the value relevance of accounting information had decreased. In other words, market activists, whether positively or negatively, did not pay attention to accounting information when they experienced excessive emotions, and they traded on massively only based on emotions and the prevailing atmosphere in the market, and this had reduced the value relevance of accounting information. In addition, the price model showed a better explanatory power in studies compared to the return model in case of structural failure. Due to the fact that the models showed different performance when considering the phenomenon of structural failures, capital market activists and researchers should pay attention to the fact that only paying attention to accounting variables in the value relevance of accounting information without considering structural failure events makes their interpretation of the value of the company in order to predict the results of the future economic activities of the companies wrong. The results of the research suggested that in accounting research that require the use of regression and econometric models in order to increase the reliability of the research results and help to predict the conditions for the users of accounting information, similar to the current research, the concepts and assumptions of economics and the fitting model based on structural failure should be used.
