On April 17, 2020, the Political Bureau of the CPC Central Committee convened a meeting, which emphasized the need to actively expand domestic demand and release consumption potential to deal with the negative impact of the epidemic on the domestic economy. In this context, various provinces and regions have successively introduced relevant policies to promote residents' consumption, and the consumer voucher policy is one of the major measures. After the Shandong Provincial Government issued the consumer vouchers implementation policy, the Liaocheng City Commerce and Investment Promotion Bureau and the Municipal Big Data Bureau took the lead in formulating the implementation plan for the issuance of consumer vouchers in Liaocheng. The study took the consumer voucher policy in Liaocheng City, Shandong Province as an example, analyzed its issuance of consumer vouchers, sorted out and summarized previous data, and explored the impact of this measure on stimulating residents' consumption through questionnaire surveys, and discussed its limitations and put forward relevant policy recommendations. This research can help improve consumer voucher policies and contribute to expanding domestic demand and restoring the economy in the future.
