【摘要】：在2008年之后我國債券發(fā)行制度發(fā)生改變,即從“額度審批制”轉變?yōu)椤昂藴手啤敝笮庞迷u級行業(yè)才開始得到重視,也進入了快速發(fā)展時期,企業(yè)主體及其證券的評級結果發(fā)揮越來越重要的作用,2016年我國國內債券市場共發(fā)行公司信用債券9.85萬億,債券融資金額遠超股票融資金額。我國債券市場的快速發(fā)展,使有關信用評級的研究再一次成為熱點。《公司債券發(fā)行試點辦法》中明確對規(guī)定,發(fā)行債券的上市公司必須取得公司主體信用評級以及本期新發(fā)行債券的評級,也就是說企業(yè)的主體信用評級在一定程度上決定了企業(yè)能否發(fā)行債券。而在發(fā)行后債券票面利率的確定同樣依賴于公司的主體信用評級,而債券票面利率又決定了企業(yè)融資成本的高低,換言之公司的主體信用評級對公司的融資成本有很大的影響。而信用評級又在很大程度上受會計信息的影響,因此研究信用評級與盈余管理相關性就很有必要。本文選取了2010-2015年間我國債券市場上存在主體信用評級的上市公司為研究對象,對存在連續(xù)主體評級的公司進行考察,研究信用評級變化動機與盈余管理行為的相關性,通過構建模型并進行線性回歸,分別從應計和真實盈余管理兩個方面對模型進行分析,得出樣本公司中信用評級上升的前一年公司普遍會進行盈余管理,且在應計盈余管理和真實盈余管理兩種方式中,公司更傾向于進行真實盈余管理,同時公司有外部需求時,會使主體信用評級對公司盈余管理的影響更明顯。最后用上市公司主體信用評級是否帶符號設置啞變量,表示公司的信用評級調整動機對模型進行穩(wěn)健型檢驗,檢驗結果與原實證分析結果一致。根據實證分析的結果,提出了相關的政策建議:(1)公司層面:不斷提升我國上市公司參與主體信用評級的主動性和管理層治理機制;(2)宏觀層面:完善信用評級指標體系,統(tǒng)一各機構的評價標準;完善資本市場的監(jiān)督機制;規(guī)范會計準則與制度,特別是會計信息的披露制度。
[Abstract]:After 2008, the bond issuance system of our country changed, that is, the credit rating industry began to be paid attention to after the "quota approval system" was changed to the "approval system", and it also entered a period of rapid development.The rating results of the main enterprise and its securities play an increasingly important role. In 2016, China's domestic bond market issued a total of 9.85 trillion corporate credit bonds, the amount of bond financing far exceeds the amount of stock financing.With the rapid development of the bond market in China, the research on credit rating has once again become a hot topic.The listed company must obtain the credit rating of the main body of the company and the rating of the new bond issued in the current period, that is to say, the main credit rating of the enterprise determines whether the enterprise can issue the bonds to a certain extent.However, the determination of bond coupon rate also depends on the main credit rating of the company, and the bond coupon rate determines the financing cost of the enterprise. In other words, the main credit rating of the company has a great impact on the financing cost of the company.The credit rating is influenced by accounting information to a great extent, so it is necessary to study the correlation between credit rating and earnings management.This paper selects listed companies with main credit rating in China's bond market from 2010 to 2015 to investigate the relationship between the motivation of credit rating and earnings management behavior.By constructing the model and linear regression, this paper analyzes the model from the two aspects of accrual and real earnings management, and concludes that earnings management is generally carried out in the companies with higher credit rating in the sample company in the previous year.And in the two ways of accrual earnings management and real earnings management, companies tend to carry out real earnings management, and when the company has external demand, the main credit rating will make the impact on earnings management more obvious.Finally, the mute variable is set with whether the main body credit rating of the listed company is marked, which indicates that the company's credit rating adjustment motive carries on the robust type test to the model, the test result is consistent with the original empirical analysis result.According to the results of the empirical analysis, this paper puts forward relevant policy recommendations at the company level: to continuously enhance the initiative of the main credit rating of listed companies in China and the governance mechanism of the management; to improve the credit rating index system;Unifying the evaluation standards of various institutions; perfecting the supervision mechanism of the capital market; standardizing accounting standards and systems, especially the disclosure system of accounting information.
