REITs, or real estate trust investment funds, are an important means of real estate securitization, which is a financial transaction process that directly converts low-liquidity, non-security real estate investments into securities assets in the capital market. The current domestic REITs are infrastructure REITs. It is to securitize a type of physical asset that can be used by external investors to purchase a certain share, like shares of a listed company, and enjoy the investment income of ordinary shareholders.
