Consumption vouchers are a kind of special vouchers, one of the tools for realizing economic policies. When the economic downturn leads to a significant decline in private consumption, the government or enterprises issue consumer vouchers to the people as payment certificates for future consumption, in the hope of increasing the people's purchasing power and desire to consume in order to revitalize consumption activities, and even to further stimulate the growth of production and investment activities, and accelerate the recovery of the economy. In this special period of financial crisis, consumer vouchers are gradually becoming one of the important means to promote sales and maintain growth.

From the effect of issuing consumption vouchers around the world, it is necessary to use consumption vouchers to kick-start consumption. On the one hand, it can be quickly converted into consumption within a specific period of time, which has a more obvious effect on boosting the economy; on the other hand, it can be directed at the middle and low-income classes that need more subsidies, reflecting the government's care for the middle and low-income classes. In addition, the consumption vouchers have obvious directional characteristics in the process of use, which is very helpful to some industries that have been hit by the epidemic to recover as soon as possible.

The issuance of consumption vouchers can form real purchasing power as soon as possible, and help the urban tertiary industry to quickly get through the epidemic's "frozen period". Since the outbreak of the epidemic, the industries closest to consumers, such as catering, retail, tourism, recreation and culture, have been the first to be hit. The issuance of consumption vouchers is conducive to the activation of dormant consumption, allowing consumption to heat up, accelerating consumption to make up for, and stimulating demand.

More attention should be paid to the precise placement of vouchers to the middle and lower income groups, especially paying high attention to the needy. For high-income earners, consumption vouchers do not stimulate consumption as much, but for the lower and middle-income earners who have a higher propensity to consume, the vouchers can, to a certain extent, help them tide over difficulties and play the role of a social stabilizer.

The main contradiction in the consumer market is that supply exceeds demand, and the issuance of consumer vouchers can help to increase demand and narrow the demand gap, which is more of a "brickbats", and it is difficult to lead to a big increase in demand in the consumer market to bring up the pressure of price increases.
