Our study leads to the following findings: First, if we take short-term debt into consideration and eliminate the IPO effect, the equity financing preference no longer exists: second, financial deficits play a more important role than traditional firm characteristics in debt ratio adjustment process, which implies that the pecking order theory can account for corporate financing behaviors to some extent: third, equity market conditions and government regulatory policies have some effect on the composition of firm external finance.

基于对中国上市公司股本融资偏好问题的重新审视，我们发现：如果将短期债务考虑在内并剔除首次公开募股的影响，股本融资偏好就不复存在；(2)在企业债务比率的调整过程中，融资缺口所起的作用超过了传统的企业特征因素，这意味着顺序偏好理论能在一定程度上解释企业的融资行为；(3)股票市场状况和政府管制政策会对企业外部融资的构成产生一定的影响。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
