【摘要】：債券市場過去幾年中的快速發(fā)展改變著中國資本市場,作為上市公司中長期債券融資的重要工具,公司債和中期票據(jù)發(fā)展迅速。為了探究上市公司發(fā)行公司債和中期票據(jù)對于自身股價的影響,明確投資者對于兩類債券發(fā)行的態(tài)度,以期對公司債和中期票據(jù)的發(fā)展以及發(fā)行人和投資者的選擇有所幫助。本文選取2007年8月到2012年12月上市公司發(fā)行的公司債和中期票據(jù)作為樣本,通過事件研究法和多元線性回歸在窗口期(-5,5)上對發(fā)行公告效應(yīng)做了研究。 研究結(jié)果發(fā)現(xiàn)公司債和中期票據(jù)的發(fā)行公告在單日上均會對股價造成顯著異常波動,但在事件窗口期上公司債發(fā)行并沒有顯著的公告效應(yīng),而中期票據(jù)發(fā)行將產(chǎn)生顯著的負(fù)公告效應(yīng)。通過截面多元線性回歸分析發(fā)現(xiàn),債券發(fā)行期限、發(fā)行規(guī)模、凈資產(chǎn)、付息債務(wù)/投入資本、投入資本回報率、市值、面值/市值均與公司債和中期票據(jù)公告效應(yīng)沒有顯著的相關(guān)性,而債券主體評級則分別在1%和5%的水平上與公司債和中期票據(jù)公告效應(yīng)顯著相關(guān),呈現(xiàn)出評級低的組別累計異常收益率更小。進(jìn)一步在窗口期中分別考察不同組別主體評級公司債和中期票據(jù)的公告效應(yīng),主體評級AA以下的公司債和中期票據(jù)在窗口期上公告效應(yīng)均顯著為負(fù),分別在5%和1%的水平下有-1.482%和-2.763%累計異常收益率,而AA及以上組別的公司債和中期票據(jù)在窗口期上均沒有顯著的公告效應(yīng)。
[Abstract]:The rapid development of the bond market in the past few years has changed the Chinese capital market. As an important tool for medium and long-term bond financing of listed companies, corporate bonds and medium-term notes have developed rapidly.

Low-rated groups show a smaller cumulative abnormal rate of return. Furthermore, in the window period, the announcement effect of corporate bonds and medium-term notes of different groups were investigated respectively. The announcement effects of corporate bonds and medium-term notes with the main rating below AA were significantly negative in the window period. At the levels of 5% and 1%, there were -1.482% and -2.763% cumulative abnormal returns, respectively, while corporate bonds and medium-term notes in AA and above groups had no significant announcement effect in the window period.
