pe giants refer to private equity investment giants.

PE private equity originated in America. At the end of the 19th century, many wealthy private bankers invested their funds in emerging industries such as oil, steel and railways with high risks through the introduction and arrangement of lawyers and accountants. This kind of investment was entirely decided by investors, and there was no special organization. This is the embryonic form of private equity funds.

after more than 5 years of development, international private equity investment funds have become an important financing means after bank loans and IPO. International private equity investment funds are large in scale, with broad investment fields, wide sources of funds and diverse participating institutions. Private equity investment funds in western countries have accounted for 4%-5% of their GDP.
