中文摘要：

沪港通的开通有利于提升中国证券市场的国际化，但资本市场双向开放也带来诸多法律风险，特别是存在管辖权和法律适用的不确定性，对证券交易所的民事责任承担产生实质影响。对于证券交易所在跨境证券交易中可能面临的民事法律风险，首先可以通过协议管辖、仲裁协议或主张管辖权豁免来避免外国法院行使管辖权；其次可以利用职能行为绝对豁免原则，减轻或免除证券交易所的民事法律责任。同时，进一步完善我国《证券法》的相关规定，以应对跨境证券诉讼的挑战。

英文摘要：

The Shanghai-HongKong Stock Connect program is beneficial to the internationalization of China＇s securities market, but the bidirectional opening of the capital market also brings a lot of legal risks, especially the uncertainty of jurisdiction and applicable law may have a substantive impact on the civil liability of a Stock Exchange. To deal with these legal risks, the first step is making jurisdiction or arbitration agreement or claiming immunity to avoid the jurisdiction of a foreign court. The Doctrine of absolute immunity based on functions can also help the Stock Exchange mitigate or being exempt from civil legal liabilities. Meanwhile, perfecting the relevant provisions of Chinese Securities Law is necessary to respond to the challenge of cross-border securities litigations.
