本研究從股價操縱因素的角度出發，利用股權集中度與盈餘管理等代理變數，探討交叉上市股價之間差異的原因，利用產生溢價所在的股票市場(A股相對H股、TDR相對港股)的股價操縱代理變數，分析溢價的產生在市場本身的限制以外，像是流動性、需求彈性等等，人為操縱的因素是否可以解釋價格差異的原因。
實證結果顯示A股與TDR之溢價不只與市場體制有關，股權集中度與法人散戶交易量等人為操縱因素也是重要的解釋因子，且溢價程度都會隨著時間的進展而降低。

Taking advantage of proxy variable of stock price manipulation like ownership concentration and earning management to examine the price difference between two market. In addition to liquidity or demand elasticity,etc, using manipulate variable of premium market(A-shares compared to H-share,TDR compared to HK-share) to investigate if manipulation can explain stock price difference.
Empricial results show that premium not only concern to market system, but also connect to manipulation factors.The degree of premium will decrease as time progressd.
