摘要 从指数和个股视角,分别采用瞬时跳跃强度模型、Tobit模型、事件研究法以及Probit模型,基于信息冲击和市场流动性冲击两个层面对A+H交叉上市股票跳跃的原因进行分析。研究发现:跳跃是多重信息共同作用的结果,经济信息对指数、个股跳跃匹配程度和幅度及强度影响有所差异,信息冲击对跳跃收益率的影响存在非对称性;当交易成本和交易量增加,则跳跃发生的概率也会增大;跳跃是信息冲击和流动性冲击共同作用的结果。 From the perspectives of index and stocks,the impacts of information shock and market liquidity shock on the stock jumps of A-shares and H-shares cross-listing are analyzed by using instantaneous jump intensity model,Tobit model,event study and Probit model. The results indicate that multiple information contributes to the jumps.Since the impacts of economic information on the index,matching degree and intensity of the stock jumps are different,the impact of information shock on jump yields is asymmetric; with the rising of transaction cost and volume,the jumps happen more often. The jumps are the combined efforts of information shock and liquidity shock.
