2、上市和IPO高定價,公司管理當局就存在著利用信息不對稱和契約不完備來進行盈余管理的強烈動機,而IPO之后業(yè)績下滑便成了一種普遍現(xiàn)象。這不僅誤導投資者、對我國證券市場的誠信基礎產生負面影響,而且也不利于我國資本市場的資源優(yōu)化配置,從而損害資本市場的信心和健康發(fā)展。本文將通過借鑒國內外學者的研究方法,并在此基礎上結合我國創(chuàng)業(yè)板的特征,對創(chuàng)業(yè)板上市公司IPO過程的盈余管理行為進行理論和實證研究,試圖從IPO的門檻、保薦人的制度、中介機構的選擇以及會計準則的完善等方面提出防范創(chuàng)業(yè)板上市公司IPO盈余管理的一些政策和建議。本文采用的是理論與實證相結合的研究方法,運用SPSS軟件對樣本數(shù)據(jù)進行處理。全文包
