摘要
本文从绑定效应和"声誉寻租"角度考察地理相近的市场间H-A逆向交叉上市公司的估值溢价,从收益率波动性视角分析H-A逆向交叉上市对内地市场的传递溢出效应。结果显示,H股回归上市受益于绑定效应可以获得显著的估值溢价,但与由境外上市时间反映的绑定信号质量无关;同时,累积效应不断下降,说明H股回归上市存在非优质公司的"声誉寻租"行为。H股回归上市对A股市场和同行业公司有显著的单向传递溢出效应,说明逆向交叉上市有助于改善新兴市场的结构和效率。
From the perspectives of binding effects and rented reputation, the authors of this paper research the premium of H-A reverse cross-listing firms listed in geographically close markets, and examine the spillover effects of H-A reverse cross-listing on home markets by return volatility. The results of the paper show that the A-share IPO of H-share firms benefits from the binding effect, and can obtain a significant valuation premium, which however is independent of the quality of binding signal decided by the duration of offshore cross-listing; meanwhile, the cumulative effect is declining, which indicates that "rented reputation" behaviors exist in non-excellent A-share IPO of H-share firms. The A-share IPO of Hshare firms has a significant one-way transitive spillover effect on the A-share markets and companies in the same industry,which indicates that the reverse cross-listing can improve the structure and efficiency of emerging markets.
