【摘要】:我國(guó)證券市場(chǎng)行政監(jiān)管的效率及效果一直以來備受詬病,,上市公司的違規(guī)行為屢見不鮮、屢禁不止,嚴(yán)重?fù)p害了投資者的利益。紀(jì)律處分的有效性反映了證券市場(chǎng)良好運(yùn)行的程度,為此,國(guó)內(nèi)外學(xué)者展開一系列理論和實(shí)證研究。本文在歸納總結(jié)國(guó)內(nèi)外相關(guān)領(lǐng)域研究文獻(xiàn)的基礎(chǔ)上,首先采用描述性統(tǒng)計(jì)方法對(duì)我國(guó)證券市場(chǎng)違規(guī)處分現(xiàn)狀進(jìn)行分析,發(fā)現(xiàn)我國(guó)監(jiān)管體制存在處分力度輕、透明度低等問題。其次以2010-2013上半年在證監(jiān)會(huì)、上海交易所和深圳交易所網(wǎng)站上公告的違規(guī)處分事件為樣本,采用事件研究法檢驗(yàn)違規(guī)處分公告對(duì)企業(yè)權(quán)益和負(fù)債的影響,分別用市場(chǎng)反應(yīng)和貸款結(jié)構(gòu)變化來衡量。結(jié)果顯示:1.在公告日后的第三和第四個(gè)交易日,涉事公司股票的累積非正;貓(bào)率顯著為負(fù),反應(yīng)滯后,持續(xù)時(shí)間短,說明從市場(chǎng)反應(yīng)維度考察的紀(jì)律處分有效性整體上較弱。2.市場(chǎng)的負(fù)面反應(yīng)程度與處分主體的權(quán)威性及處分力度呈正相關(guān),對(duì)違規(guī)對(duì)象及違規(guī)原因并不敏感,僅對(duì)證券交易違規(guī)表現(xiàn)出明顯的負(fù)面反應(yīng)。3.紀(jì)律處分使得違規(guī)企業(yè)的貸款總量下降,長(zhǎng)期和短期信用貸款比例明顯降低,導(dǎo)致企業(yè)貸款成本顯著增加,說明從對(duì)貸款的影響維度考察,紀(jì)律處分是有效性的。
