The scope of private equity funds is wider, including all unlisted funds such as venture funds, private equity funds, hedge funds and private equity investment funds.

It is worth noting that because real estate investment is an independent large investment category, there are real estate private equity funds and real estate private equity funds (real estate private equity or real estate PE) in the investment industry. There are some differences between them, but sometimes it is difficult to distinguish them. It is more appropriate to say "real estate private equity fund" in Chinese.

In addition, private equity investment fund (PE) and private equity investment fund are two kinds of funds whose names are easily confused, but their essence is completely different. Private equity investment funds mainly invest in the equity of unlisted enterprises, which belongs to the category of primary equity market and will accompany the growth stage and development process of enterprises. Private equity investment funds mainly invest in the secondary securities market.
