【摘要】：公司債券作為面向上市公司的新興債務融資方式,能否為企業(yè)發(fā)展帶來福音?既往以來,企業(yè)債務融資的理論研究主要包括債務融資類型結(jié)構(gòu)、債務期限結(jié)構(gòu)、債務水平結(jié)構(gòu)等問題。本文重點關(guān)注屬于債務融資類型之一的公司債券,研究討論企業(yè)的債務融資方式,通過公司債券發(fā)行對企業(yè)投資行為影響的實證分析,檢驗公司債券發(fā)行對企業(yè)非效率性投資行為的影響。 本文在回顧和梳理國內(nèi)外相關(guān)文獻基礎上,選取已成功發(fā)行過公司債券的125家A股上市公司(截至2011年12月31日)從2005至2010年度的共681組年度數(shù)據(jù),通過對比公司債券發(fā)行前后債務融資對企業(yè)非效率性投資行為影響,建立非效率投資動因的解釋模型,研究債務融資方式對企業(yè)投資行為的影響。四組模型分別從資產(chǎn)負債率、長期借款和短期借款存量、長期借款和短期借款增量、公司債券規(guī)模等解釋變量出發(fā)探討債務融資方式和期限結(jié)構(gòu)對非效率投資的影響。在得出整體樣本表現(xiàn)出長期投資不足與投資過度并存的非效率性投資環(huán)境的基礎上,進一步研究了債務融資與非效率投資之間的制約關(guān)系。實證檢驗發(fā)現(xiàn),企業(yè)的長期債務融資和短期債務融資與非效率投資之間存在負相關(guān)關(guān)系,即負債對非效率投資行為產(chǎn)生抑制作用,而且長期債務抑制作用更為明顯,當檢驗對象變?yōu)楫斊谛略鲩L期負債和短期負債時,這種負相關(guān)關(guān)系更加顯著,長期負債融資的擬合優(yōu)度高于短期負債,即長期負債更能約束企業(yè)的投資行為。雖然我國資本市場長期存在短期債務融資替代長期債務融資的問題,但是研究長期債務與企業(yè)投資行為的聯(lián)系將有利于拓展資本市場的融資外沿；另一方面,公司債券作為長期債務融資方式的一種,其對非效率投資能發(fā)揮抑制作用。鑒于長期債務融資對非效率投資制約的效應,推動公司債券發(fā)展有利于提高企業(yè)的投資效率,促進有效投資。
[Abstract]:Corporate bonds, as a new debt financing method for listed companies, can bring good news for the development of enterprises? In the past, the theoretical research of corporate debt financing mainly includes debt financing type structure, debt maturity structure, debt level structure and so on. This paper focuses on corporate bonds, one of the types of debt financing, studies and discusses the debt financing methods of enterprises, and analyzes the impact of corporate bond issuance on corporate investment behavior through empirical analysis. To examine the impact of corporate bond issuance on the non-efficient investment behavior of enterprises. On the basis of reviewing and combing the relevant literature at home and abroad, this paper selects 125 A-share listed companies (as of December 31, 2011), which have successfully issued corporate bonds, from 2005 to 2010, with a total of 681sets of annual data. By comparing the influence of debt financing on enterprises' non-efficient investment behavior before and after the issuance of corporate bonds, this paper establishes an explanatory model of the inefficiency investment motivation, and studies the influence of debt financing mode on enterprises' investment behavior. The four groups of models discuss the influence of debt financing mode and maturity structure on non-efficient investment from the explanatory variables of asset-liability ratio, long-term borrowing and short-term borrowing stock, long-term borrowing and short-term borrowing increment, corporate bond size and so on. On the basis of the conclusion that the whole sample shows the inefficiency investment environment in which long-term underinvestment and over-investment coexist, the restriction relationship between debt financing and inefficient investment is further studied. The empirical results show that there is a negative correlation between long-term debt financing and short-term debt financing and inefficient investment, that is, debt has an inhibitory effect on inefficient investment behavior, and long-term debt inhibition is more obvious. The negative correlation is more significant when the object is the new long-term liabilities and short-term liabilities, and the goodness of fit of long-term debt financing is higher than that of short-term liabilities, that is, long-term liabilities can more constrain the investment behavior of enterprises. Although there is a long-term problem of short-term debt financing instead of long-term debt financing in China's capital market, studying the relationship between long-term debt and enterprise investment behavior will help to expand the financing externalities of the capital market; on the other hand, As one of the long-term debt financing methods, corporate bonds can inhibit the non-efficient investment. In view of the effect of long-term debt financing on inefficient investment, promoting the development of corporate bonds is conducive to improving the investment efficiency of enterprises and promoting effective investment.
