Research on e-government construction has a long-standing history. Recent academic developments have shown that numerous e-government websites face challenges in providing satisfactory e-services to citizens. Consequently, citizens are less inclined to use these websites continuously, as they fail to meet their expectations and needs. This seems to be a common problem in many countries. The majority of researchers have examined this issue from the perspective of internal factors within administrative organizations. However, previous studies have rarely focused on the influence of external factors, such as cultural variables, on the continuous usage of e-government websites by citizens. Drawing upon Hofstede's cultural model, this study establishes a framework for examining the factors influencing citizens' continuous use of e-government websites. This paper, employing quantile regression, reveals that collectivism, masculinity, long-term orientation, and constraint culture exhibit varying degrees of influence on different levels of continuous use of China's e-government websites. In light of these findings, this study suggests that the government should pay attention to the cultural aspects of e-government websites and provide culturally adaptive e-government services to better meet the public's needs and expectations.
