2. The word investment has several related meanings in finance and economy. It involves the accumulation of property in order to gain benefits in the future. Technically speaking, this word means "the act of putting something in another place" (which may initially be related to people's clothes or "dresses"). From the financial point of view, compared with speculation, the investment period is longer, and it is more inclined to obtain some sustained and stable cash flow income in a certain period of time in the future, which is the accumulation of future income. Investment refers to the economic behavior that a specific economic entity invests a sufficient amount of funds or physical currency equivalents in a certain field within a certain period of time in order to obtain income or capital appreciation in the foreseeable future. It can be divided into physical investment, capital investment and securities investment.
