恒生指数受什么监管

中文段落：

恒生指数，作为香港股市的重要指标，其监管机制备受关注。恒生指数的监管主要受到香港证券及期货事务监察委员会（证监会）的监管。证监会是香港金融市场的监管机构，负责监管香港的证券及期货市场，保障市场的公平、透明和有效。

在监管恒生指数方面，证监会主要采取以下措施：首先，对恒生指数的编制和管理进行规范，确保指数编制的科学性和公正性；其次，对恒生指数成分股公司进行监管，确保公司符合上市要求，并遵守相关法规；再次，对恒生指数的交易活动进行监管，防止市场操纵和不当交易行为的发生。

除了证监会的监管外，恒生指数还受到香港联合交易所（联交所）的监管。联交所是香港唯一的股票交易所，负责监管上市公司的运作和交易活动。联交所通过制定严格的上市标准和监管规则，确保恒生指数成分股公司的质量和透明度。

综上所述，恒生指数受到香港证监会和联交所的双重监管，确保了指数的公正、透明和有效。这种监管机制为投资者提供了良好的投资环境，促进了香港股市的健康发展。

The Hang Seng Index, as an important indicator of the Hong Kong stock market, is subject to close scrutiny of its regulatory mechanism. The Hang Seng Index is primarily regulated by the Securities and Futures Commission (SFC) of Hong Kong. The SFC is the regulatory body for Hong Kong's financial markets, responsible for overseeing the securities and futures markets to ensure fairness, transparency, and efficiency.

In regulating the Hang Seng Index, the SFC takes the following measures: firstly, it standardizes the compilation and management of the index to ensure scientific and impartial index compilation; secondly, it oversees the constituent companies of the Hang Seng Index to ensure they meet listing requirements and comply with relevant regulations; thirdly, it monitors trading activities related to the Hang Seng Index to prevent market manipulation and improper trading practices.

Apart from the SFC's regulation, the Hang Seng Index is also subject to supervision by the Hong Kong Stock Exchange (HKEX). As the only stock exchange in Hong Kong, the HKEX is responsible for regulating the operations and trading activities of listed companies. Through the establishment of strict listing standards and regulatory rules, the HKEX ensures the quality and transparency of constituent companies of the Hang Seng Index.

In conclusion, the Hang Seng Index is subject to dual regulation by the SFC and the HKEX, ensuring its impartiality, transparency, and effectiveness. This regulatory mechanism provides investors with a sound investment environment, promoting the healthy development of the Hong Kong stock market.
