31 1. INTRODUCTION The formation and development of the economy of information and knowledge in production processes directly depend on economic progress and social development. This means the continuous intellectualization of the population. Intellectual potential becomes the main condition for economic growth, and intellectual capital, together with human capital, is the most important and valuable resource for achieving this goal [1]. The essence of intellectual capital is complex, characterized by a significant number of aspects. In our opinion, the definition of intellectual capital should specify its nature as much as possible and cover all aspects of this concept. Taking this into account and generalizing the views of intellectual capital researchers, we can give the following definition: intellectual capital is a stock of knowledge and information useful to a person, enterprise, region, or country, which is used in economic activity, ensures effective economic development, and the achievement of progressive social standards. Publications in scientific research on the development of small and medium-sized businesses in ASEAN countries claim that intellectual capital, and especially human capital, occupied a leading place in economic growth in the economies of Malaya, Thailand, and Vietnam [2]. In these studies of the impact of IS on the efficiency of the company, researchers referred to the dependence of return on assets (ROA) on IS. For the assessment of IS, the most productive method, VAIC, was proposed at that time [3]. In this case, the MVAIC model was used, where the calculations were based on the assessment of value added (VA) to find indicators of human capital-HC, where HCE = VA/HC, company capital (CE), which was determined by deducting its net assets from intangible assets - CEE = VA/CE, organizational capital (structural)- SC, where (SCE = SC/VA) and relational capital - (RC), where RCE = RC/VA. Then the modified MVAIC coefficient determined the efficiency of the company’s IS, i.e., MVAIC = HCE + SCE
