摘要
Base on panel data of manufacturing and high-tech industry companies which discoursed R ＆ D expenditure in financial statements from 2004 to 2011, this paper studies the relationship between debt financing and corporate R ＆ D expenditure under different grow opportunities by using the robust fixed effects that Daniel Hoechle proposed m 2007. The results show that there is not a ＂increasing first, decreasing later＂ non-linear relationship but a ＂double negative＂ relationship between debt level and corporate R ＆ D expenditure. And the ＂double negative＂ relationship has a different mechanism in different growth companies.
