系统性风险是指整个金融系统或市场体系中存在的风险，它具有广泛的影响力和不可预测性。系统性风险通常包括市场风险、信用风险和流动性风险等。

市场风险是指由于市场价格波动而产生的风险。例如，股票市场或外汇市场的价格波动可能导致投资者损失资金。这种风险不仅影响投资者，还对整个金融系统产生影响，因为金融机构通常持有许多股票和债券等金融资产。

信用风险是指借款人无法按期偿还债务而产生的风险。如果一家大型公司无法偿还其债务，这可能会对整个金融系统产生影响，导致其他公司和投资者遭受损失。

流动性风险是指金融机构无法按照合理的价格及时买卖金融资产而产生的风险。如果市场流动性不足，金融机构可能无法在需要时以合理的价格卖出其资产，这可能导致其遭受损失。

系统性风险对整个金融系统和市场体系都有很大的影响，因此需要采取有效的风险管理措施来降低其影响。这包括建立更加稳健的金融体系、加强监管、提高透明度等措施。

英文：

Systemic risk refers to the risk that exists in the entire financial system or market system, which has a wide range of influence and unpredictability. Systemic risks typically include market risk, credit risk, and liquidity risk.

Market risk refers to the risk resulting from market price fluctuations. For example, price fluctuations in the stock market or foreign exchange market may cause investors to lose money. This kind of risk not only affects investors, but also has an impact on the entire financial system because financial institutions typically hold many financial assets such as stocks and bonds.

Credit risk refers to the risk that a borrower cannot repay its debt on time. If a large company cannot repay its debt, it may have an impact on the entire financial system, causing losses to other companies and investors.

Liquidity risk refers to the risk that a financial institution cannot buy or sell financial assets at a reasonable price in a timely manner. If market liquidity is insufficient, financial institutions may not be able to sell their assets at a reasonable price when needed, which may lead to their losses.

Systemic risk has a great impact on the entire financial system and market system, so effective risk management measures need to be taken to reduce its impact. This includes establishing a more robust financial system, strengthening supervision, increasing transparency and other measures.
