The development of information technology has brought the changes to the rapid growth and competition of online website stores in Indonesia. Online store businesses are aggressively making various marketing efforts to influence consumers to shop on their website. The Indonesian government has seriously issued several regulations regarding online commerce or e-commerce since 1997. Thus, this phenomenon has encouraged researchers to analyze the influence of website quality and the application of Government Regulations related to Ecommerce Law through website verification of the behavior of impulse buying, which was conducted by the millennial generation online. This paper presents an empirical investigation to study the effect of website quality and government regulations on online impulse buying behavior among some undergraduate students at Brawijaya Malang University. The results have confirmed that both website quality and government regulations had some impacts on online impulse buying behavior.
