摘要
对主流IPO抑价理论中发行价低于内在价值的假定提出质疑,运用剩余收益估值模型、随机边界定价模型和回归模型,首次检验了我国创业板市场上市公司IPO发行定价合理性。结果表明,我国创业板IPO发行定价偏离内在价值,具有显著的下边界特征,存在价格泡沫。进一步检抑价原因,发现与国外IPO发行定价时的故意抑价不同,二级市场的投机行为是产生抑价的主要原因。
This paper challenges the assumption of IPO issue price below the intrinsic value in the mainstream IPO underpricing theory.We firstly make an empirical test on IPO issue price rationality in China growth enterprise market based on using the residual income valuation model,stochastic frontier model and regression model.The test results show IPO issue price in China growth enterprise market deviates from intrinsic value,having significant the lower frontier characteristics,existing price bubble.Furthermore,we make an empirical test on IPO underpricing causes.We find it is different from deliberate IPO underpricing in the foreign country,speculation behavior in secondary market is the main cause of IPO underpricing.
