Research On The Influence Of Text Characteristics Of Bank Annual Reports On Market Discipline

From the perspective of financial regulatory reform practice,it is evident that Chinese banks’ market discipline has significantly improved in recent years,and the function of the current market discipline is increasingly prominent.However,the deepening reform of market discipline is becoming a subject of higher demand for academic and practical researchers under the new situation.For a long time,due to the existence of full implicit deposit guarantee and interest rate control in China’s banking industry,depositors lacked motivation to supervise banks,and the absence of differences among banks’ deposit interest rates made it difficult for the market discipline mechanism to play its due function.However,with the introduction of the deposit insurance system and the exploration of the bank bankruptcy system by regulators,along with the scandals such as the bankruptcy of Baoshang Bank and the outbreak of depositors’ deposit loss in rural banks in Henan province,the motivation of Chinese depositors to choose and supervise banks has gradually increased.Moreover,China removed the ceiling on deposit interest rates in 2015 and improved the market price mechanism for bank deposits,which further enhanced the effectiveness of market discipline.As the importance of market discipline in enhancing regulatory efficiency gradually emerges,academic and practical researchers have raised their requirements for enhancing market discipline.High-quality information disclosure is a prerequisite for the effective implementation of market discipline.The annual report plays a crucial role as the most important information carrier of bank information disclosure.Within the annual report,the text serves as a significant component and primary source for stakeholders to obtain bank information.Stakeholders rely on the bank annual report text as a comprehensive and focused description of bank annual information.Ensuring the readability of the text information in the annual report,improving the comparability of the text information between different periods and different banks,and guaranteeing the objectivity of the tone of the text to prevent misleading statements are critical factors for effectively leveraging the function of market discipline.However,most of the existing research has primarily focused on the influence of quantitative data in bank annual reports on market discipline,while relatively neglecting the role of descriptive text information.Therefore,this paper aims to fill the gap by focusing on the annual report text information,specifically from the three dimensions of "readability,comparability,and intonation." Combining market discipline theory,bank information disclosure theory,and text characteristics theory,this study systematically investigates the impact of the bank annual report text information characteristics on market discipline,both in theoretical and practical terms.The main research and conclusions of this paper are as follows:First,I manually collected 1286 annual reports from 210 Chinese banks covering the period from 2004 to 2019.I used a Chinese word segmentation algorithm to divide the text of the annual reports into words and then applied text analysis methods such as the text vector method and word frequency analysis to measure and analyze the readability,comparability,and tone of these reports.The results show that Chinese banks’ annual reports have relatively low readability,high comparability,and a generally positive tone.Specifically,although the common words account for a relatively high proportion,the average length of the annual reports is relatively long,and the chapters are more complex,containing more sub-common words and professional terms in accounting,finance,and law.The text of the annual reports is relatively comparable between different periods and different banks.The number of positive words in the annual report is higher,and is twice as high as the average number of negative words.Moreover,the characteristics of the annual report text vary depending on the ownership and listing conditions of the banks.State-owned banks’ annual reports have higher readability,comparability,and a more positive tone than the average level of banks.Joint-stock banks’ annual reports have higher comparability but less readability and a negative tone.City commercial banks’ annual reports have higher readability and a more positive tone,but the comparability is low.Rural commercial banks’ annual reports have low readability and comparability,and a negative tone.Finally,the annual reports of listed banks are less readable but have higher comparability and a more positive tone,whereas non-listed banks are more readable but less comparable and have a more negative tone.Second,this paper employs the dynamic panel data method and the generalized moment estimation(GMM)method to investigate the impact of bank annual report text information’s readability on market discipline.The study finds that enhanced readability of the text in the annual reports leads to improved market discipline effectiveness.The rationale is that when the text is easy to understand,clear,and fluent,it reduces the cost of interpreting information for depositors and increases their risk awareness.Moreover,the study also finds that the effect of readability on market discipline is more significant for small and medium-sized banks and nonlisted banks,taking into account the size preference of depositors and the level of bank information disclosure.After incorporating policy influencing factors,such as interest rate liberalization and deposit insurance systems,the study further demonstrates that these reforms optimize the market price mechanism of deposit interest rate,improve the motivation of depositors in small and medium-sized banks to supervise banks,and deepen the impact of readability of annual report text information on market discipline.Third,this study investigates the impact of the comparability of annual reports on market discipline.The results indicate that improving the comparability of banks’ annual reports with historical and peer data can enhance market discipline.This is because comparable annual reports facilitate a better understanding of the dynamic changes in bank risks and interbank conditions,which ultimately increases the effectiveness of market discipline.Furthermore,the study finds that this effect is more pronounced among small and medium-sized banks and nonlisted banks,taking into account the size preference of depositors and the level of bank information disclosure.After factoring in the policy implications of financial deepening reform,such as interest rate liberalization and deposit insurance systems,the study finds that these reforms have further improved the comparability of annual reports in enhancing the risk sensitivity of depositors and strengthening market discipline.Fourth,this paper investigates the impact of tone on market discipline.The findings reveal that a more positive tone in the annual report of sampled banks weakens the effectiveness of market discipline on deposit channels.This suggests that the positive tone of the annual report mainly serves the purpose of impression management on depositors,and embodies misleading characteristics that reduce the effectiveness of market discipline.Taking into account the difference in the information disclosure level of banks,this effect is found to be significant in non-listed banks with poor information disclosure levels.In contrast,for listed banks,the net tone of the annual report functions as incremental information and significantly enhances the effectiveness of market discipline.Further investigation on the effect of financial reform on this phenomenon reveals that interest rate liberalization optimizes the price mechanism of bank deposits and strengthens the incremental information effect in the annual report tone.However,the deposit insurance system worsens the impression management effect of the net tone of annual reports for non-listed banks.Additionally,after an in-depth analysis of the composition of the net tone of the annual report,it is found that the length and information content of the positive words in the annual report are higher than those of negative words,and the impact of the net tone of the annual report on market discipline is mainly driven by the positive words.Fifth,this paper summarizes and analyzes the empirical research results,and presents recommendations from three perspectives: banks,regulators,and depositors.Regarding banks,this paper suggests that they should strike a balance between readability and professionalism,comparability and usefulness,and accuracy and vividness in their information disclosure.With regards to supervision,this paper argues that regulators should refine information disclosure requirements,improve the information disclosure evaluation system,establish a text information authentication system,and assess and manage bank information disclosure behavior using appropriate fintech tools.From the perspective of depositors,this paper emphasizes the need for them to enhance their financial literacy,analyze changes in bank operations dynamically,gather information from different sources,and strengthen multicorroboration analysis,to improve their risk identification ability.The research findings presented in this paper provide a comprehensive investigation of the influence of information disclosure on market discipline,specifically from the perspective of text characteristics.These results serve as a theoretical basis and empirical support for regulatory authorities to better regulate the narrative content of annual reports and prevent the manipulation of bank annual report text.Therefore,this paper holds both theoretical significance and practical application value.The main innovations of this paper are as follows:First,this paper contributes to the research on bank information disclosure by expanding its scope beyond the completeness and accuracy of quantitative data.While previous studies have mainly focused on these aspects,this paper innovatively evaluates the descriptive characteristics of bank information disclosure,particularly the readability,comparability,and tone of bank annual report text.By assessing these dimensions,the paper seeks to improve the quality of accounting information and prevent misleading statements in annual reports.Furthermore,the analysis takes into account the heterogeneity of banks based on their equity nature and listing situation.This approach enriches the traditional research perspective on evaluating bank financial data information disclosure and expands the understanding of bank information disclosure.Second,this paper enriches the research content on market discipline.While prior research has mainly focused on the influence of the quantity of bank information disclosure on market discipline,this paper examines the influence of the quality of information disclosure,particularly the text features of information disclosure,on market discipline.The analysis considers differences in influence across various scales and levels of information disclosure.This approach not only fills a gap in the existing literature on the economic consequences of bank annual report characteristics,but also contributes to a deeper understanding of the influence of information disclosure on market discipline.Third,this paper contributes to the evaluation of financial reforms from the perspective of market discipline.While some studies have examined the effects of interest rate liberalization and the deposit insurance system on the banking sector,few have explored how financial reforms impact market discipline.While these reforms have theoretically enhanced market price mechanisms and the motivation of depositors to supervise banks,their actual effects on market discipline have not been thoroughly examined.Therefore,this paper provides an indepth analysis of the influence of interest rate liberalization and the deposit insurance system on the market discipline effect of bank annual report text characteristics.By doing so,it offers valuable insights into the effectiveness of China’s financial reform.
