Policy-makers generally consider entrepreneurship to be instrumental for economic growth and technological progress. The entrepreneurship process is shaped by the presence of entre-preneurship environment. Since entrepreneurship self-efficacy perceptions are also vital to new venture creation and its performance, entrepreneurship self-efficacy literature has gener-ated interesting insights, the research on impact of environment on entrepreneurship self-efficacy is still less evident. This study tests the influence of some environmental cognitive support elements on the entrepreneurship self-efficacy. A cross-sectional research design in Vietnamese students with quantitative questionnaire approach was conducted. The sample consists of 350 students in 6 business and economics universities in Hanoi. The result of the multiple regression analysis reveals that environments’ support-factors including perceived financial and non-financial supports, and social supports are significantly related to perceived entrepreneurship self-efficacy of students. The study findings highlight some implications for government to reinforce policies encouraging entrepreneurship in university students.
