本研究的結論是: 1 )中國股票市場的微觀交易結構並不是採取做市商制度,且2 3的股票不能流通,流通股規模很小,存在著股票股利事件后的快速「填權」效應,使股票價格快速回升,股票股利發放事件的稀釋價格作用無法發揮,也就無法達到「最適價格」 ; 2 )中國股市的買賣價差的含義發生了變化,不再是實際交易成本的反映,只是可能交易成本的反映,因而很大程度上代表了股價的波動意願,並不具有完全意義上的流動性含義。 3 )就換手率而言,它既是流動性的衡量指標,也是最常用的衡量投機性的指標。換手率指標只能說明流動性的一個側面,在中國衡量流動性是有缺陷的。Research on peculiarity of wave in the downstream of diffluent piers with low ridge
