"Individual consumption refers to the behavior of individuals to purchase goods and services in the market, and is also an important indicator for measuring a country's economic activity. Personal consumption is composed of factors such as household, individual, non-profit institution and government consumer spending.

The importance of private consumption lies in its contribution to economic growth. Personal consumption is an important component of gross domestic product (GDP), often accounting for a significant portion of GDP. In an economy, an increase in private consumption leads to an increase in domestic demand, which stimulates growth in production and employment. Therefore, the development of an economic system is inseparable from the support of personal consumption.

The size and character of individual consumption often depend on individual income levels, confidence, and spending habits. Generally speaking, when personal income increases, they tend to increase their consumption expenditures because they have more disposable income. In addition, personal confidence can also affect personal consumption expenditure, for example, during economic prosperity, individuals usually have higher confidence and are more inclined to increase their consumption expenditure. Spending habits are also an important factor affecting personal consumption, some people may be more inclined to save and invest, while others may be more inclined to consume and buy.

In short, personal consumption is an integral part of economic activity. Its contribution to economic growth is obvious, but attention also needs to be paid to the sustainability and quality of consumption to ensure long-term stability and sustainable development of the economy. "
