from the external auditor’s perspective by using measurement scale proposed by Annukka Jokipii (2009) The study is among the very few studies in Vietnam empirically examines internal control effectiveness as well as suggest the reference internal control components used in practice To assess the internal control components and internal control effectiveness, a study of 236 external auditors who audited the operation of companies in Vietnam in 2011 was conducted Even though some unexpected outcomes have incurred, “control environment” and “monitoring” are not supported in their relationship with “the reliability of financial report”; “information and communication” is not supported in the relationship with “the compliance with laws and regulations”, the empirical results indicate that all remaining internal control components (Control environment, risk assessment, control activities, information and communication, and monitor) have significant positive effect on internal control effectiveness which are also considered the company objectives: efficiency and effectiveness of operation, reliability of financial report, compliance with laws and regulations Key words: Internal control components, Internal control effectiveness 64 ðánh giá rủi ro Phản ñối Theo tơi, mục tiêu hoạt động Cơng ty đáng tin cậy hợp lý Các Thành viên quản lý chủ ñộng ñánh giá rủi ro
