3月13日，上交(jiao)(jiao)所下發了《關于征求優化大宗(zong)交(jiao)(jiao)易(yi)機(ji)(ji)制(zhi)有關措施意見的函》，從四個方面優化大宗(zong)交(jiao)(jiao)易(yi)機(ji)(ji)制(zhi)，其中最引人關注的莫過(guo)于降低大宗(zong)交(jiao)(jiao)易(yi)門檻。

一，延長(chang)大宗交(jiao)易時(shi)間(jian)。上(shang)交(jiao)所計劃在(zai)競價交(jiao)易市場收盤(pan)(pan)后(hou)增加一個獨立的大宗交(jiao)易時(shi)段(duan)（16：00~20：00）。投資者通過大宗交(jiao)易系統提(ti)交(jiao)成交(jiao)申報(bao)，當日成交(jiao)，次日清(qing)算。同時(shi)，在(zai)該時(shi)段(duan)增加當日有效的“收盤(pan)(pan)價格(ge)申報(bao)”類型訂單(dan)，買賣雙方均按(an)當日競價交(jiao)易市場收盤(pan)(pan)價格(ge)進(jin)行申報(bao)，上(shang)交(jiao)所根(gen)據時(shi)間(jian)優(you)先、數量(liang)優(you)先的原則成交(jiao)。

二，降(jiang)低大(da)宗(zong)(zong)(zong)交易(yi)門檻。上交所計(ji)劃等(deng)比例調整(zheng)(zheng)A股、B股和基金的大(da)宗(zong)(zong)(zong)交易(yi)最低限額，調整(zheng)(zheng)計(ji)劃為：A股大(da)宗(zong)(zong)(zong)交易(yi)最低額度由“50萬(wan)(wan)(wan)(wan)(wan)股或(huo)300萬(wan)(wan)(wan)(wan)(wan)元(yuan)(yuan)(yuan)人(ren)民(min)(min)幣(bi)(bi)”調整(zheng)(zheng)至“10萬(wan)(wan)(wan)(wan)(wan)股或(huo)60萬(wan)(wan)(wan)(wan)(wan)元(yuan)(yuan)(yuan)人(ren)民(min)(min)幣(bi)(bi)”；B股由 “50萬(wan)(wan)(wan)(wan)(wan)股或(huo)30萬(wan)(wan)(wan)(wan)(wan)美元(yuan)(yuan)(yuan)”調整(zheng)(zheng)至“10萬(wan)(wan)(wan)(wan)(wan)股或(huo)6萬(wan)(wan)(wan)(wan)(wan)美元(yuan)(yuan)(yuan)”；基金由“300萬(wan)(wan)(wan)(wan)(wan)份或(huo)300萬(wan)(wan)(wan)(wan)(wan)元(yuan)(yuan)(yuan)人(ren)民(min)(min)幣(bi)(bi)”調整(zheng)(zheng)至“60萬(wan)(wan)(wan)(wan)(wan)份或(huo)60萬(wan)(wan)(wan)(wan)(wan)元(yuan)(yuan)(yuan)人(ren)民(min)(min)幣(bi)(bi)”；國債(zhai)(zhai)及債(zhai)(zhai)券回購由“1萬(wan)(wan)(wan)(wan)(wan)手或(huo)1000萬(wan)(wan)(wan)(wan)(wan)元(yuan)(yuan)(yuan)人(ren)民(min)(min)幣(bi)(bi)”調整(zheng)(zheng)至“100手或(huo)10萬(wan)(wan)(wan)(wan)(wan)元(yuan)(yuan)(yuan)人(ren)民(min)(min)幣(bi)(bi)”；其他債(zhai)(zhai)券由“1000手或(huo)100萬(wan)(wan)(wan)(wan)(wan)元(yuan)(yuan)(yuan)人(ren)民(min)(min)幣(bi)(bi)”調整(zheng)(zheng)至“50手或(huo)5萬(wan)(wan)(wan)(wan)(wan)元(yuan)(yuan)(yuan)人(ren)民(min)(min)幣(bi)(bi)”。

三，放寬漲(zhang)跌幅(fu)限制(zhi)范圍。上交(jiao)所計劃通過大宗(zong)交(jiao)易系統(tong)提供帶鎖(suo)定(ding)(ding)期(qi)大宗(zong)交(jiao)易機(ji)制(zhi)。受讓投資者購(gou)入(ru)的(de)股份被鎖(suo)定(ding)(ding)一定(ding)(ding)時期(qi)不得轉讓，大宗(zong)交(jiao)易成交(jiao)價格的(de)漲(zhang)跌幅(fu)限制(zhi)幅(fu)度越寬，鎖(suo)定(ding)(ding)期(qi)越長。初步考慮鎖(suo)定(ding)(ding)期(qi)大宗(zong)交(jiao)易分為(wei)(wei)兩檔：漲(zhang)跌幅(fu)限制(zhi)范圍為(wei)(wei)前(qian)收盤價格的(de)70%~130%，鎖(suo)定(ding)(ding)期(qi)限至少(shao)為(wei)(wei)6個月；漲(zhang)跌幅(fu)限制(zhi)范圍為(wei)(wei)前(qian)收盤價格的(de)50%~150%，鎖(suo)定(ding)(ding)期(qi)限至少(shao)為(wei)(wei)1年。

四，增加大宗交(jiao)易的申(shen)報類型(xing)。上交(jiao)所計(ji)劃推出多日有(you)效的 “全部(bu)成交(jiao)否則撤(che)銷(xiao)的固(gu)定價格申(shen)報”。
