港股通是中国内地投资者进行境外股票投资的重要渠道之一，自2014年11月17日推出以来，受到了广大投资者的热烈欢迎。那么，港股通是什么时候开始的呢？

2014年11月17日，沪港通正式开通，标志着港股通正式启动。沪港通是由上海证券交易所和香港联合交易所共同推出的，允许两地投资者通过当地证券公司或经纪商，买卖对方交易所上市的股票。此后，港股通逐渐成为内地投资者进行境外投资的重要途径之一。

港股通的开通，不仅为内地投资者提供了更多的投资机会和渠道，同时也促进了香港金融市场的繁荣和发展。通过港股通，内地投资者可以更加方便地投资香港市场，增加了香港市场的流动性和活跃度。同时，香港市场也为内地投资者提供了更加多样化的投资选择和风险管理工具。

在港股通推出初期，由于市场对这一新事物的认知度和接受度有限，投资者参与度相对较低。但是随着时间的推移和市场的逐步成熟，越来越多的投资者开始认识到港股通的价值和优势，参与度也逐渐提高。尤其是近年来，随着中国经济的崛起和香港市场的逐渐稳定，港股通成为了内地投资者进行境外投资的首选之一。

总的来说，港股通的开通对于中国资本市场的开放和发展具有重要意义。它不仅为内地投资者提供了更多的投资机会和渠道，同时也促进了香港金融市场的繁荣和发展。随着市场的不断成熟和完善，相信港股通将会在未来发挥更加重要的作用。

Hong Kong Stock Connect is an important channel for Chinese mainland investors to invest in overseas stocks. Since its launch on November 17, 2014, it has been warmly welcomed by investors. So, when did Hong Kong Stock Connect start?

On November 17, 2014, Shanghai-Hong Kong Stock Connect was officially launched, marking the official start of Hong Kong Stock Connect. Shanghai-Hong Kong Stock Connect was jointly launched by the Shanghai Stock Exchange and the Hong Kong Stock Exchange, allowing investors in both places to buy and sell stocks listed on the other exchange through local securities companies or brokers. Since then, Hong Kong Stock Connect has gradually become an important way for mainland Chinese investors to invest overseas.

The launch of Hong Kong Stock Connect not only provides more investment opportunities and channels for mainland Chinese investors, but also promotes the prosperity and development of Hong Kong's financial market. Through Hong Kong Stock Connect, mainland Chinese investors can invest in the Hong Kong market more conveniently, which increases the liquidity and activity of the Hong Kong market. At the same time, the Hong Kong market also provides mainland Chinese investors with more diversified investment options and risk management tools.

In the early stage of the launch of Hong Kong Stock Connect, due to the limited awareness and acceptance of this new thing by the market, the participation of investors was relatively low. However, with the passage of time and the gradual maturity of the market, more and more investors have begun to recognize the value and advantages of Hong Kong Stock Connect, and participation has gradually increased. Especially in recent years, with the rise of the Chinese economy and the gradual stabilization of the Hong Kong market, Hong Kong Stock Connect has become one of the first choices for mainland Chinese investors to invest overseas.

Overall, the launch of Hong Kong Stock Connect is of great significance for the opening up and development of China's capital market. It not only provides more investment opportunities and channels for mainland Chinese investors, but also promotes the prosperity and development of Hong Kong's financial market. With the continuous maturity and improvement of the market, I believe that Hong Kong Stock Connect will play a more important role in the future.
