Smart home appliances are an inevitable trend for future development, but COVID-19 has affected people's consumption structure. This study aims to investigate the consumption intention of smart home appliances after COVID-19 among Chinese residents and examine whether they differ based on gender, age, population size, education level, and income. A random sampling survey was used to collect 1599 questionnaire data. Use descriptive and differential analysis of SPSS 27 to analyse the collected data. The results found that the mean score of residents to consume smart appliances was 3.82, and the mean of repeated consumption intention is the highest, followed by the initial consumption, and the intention to pay more money has the lowest mean score. Additionally, the study found no significant difference in the gender and income of residents on their intention to consume smart home appliances. Meanwhile, there were significant differences in age, education level, and population size.
