Three main components represent the pillars of this research: Human Economic Security (HES), Islamic economics, and the Malaysian economy and policies addressing economic insecurities. HES is part of Human Security (HS), and both are presented in this research from the Islamic perspective to relate to both Islamic economics and Malaysia, the constitutionally Islamic country. To reach a conclusion regarding the subject, the researcher asks the question: "Can Malaysia actualize HES on the bases of equity and justice for all its citizens through enlarging and enhancing the performance of the Islamic Voluntary Economic Sector (IVES) institutions, specifically the redistributive institution of zakat?" The methodological approach of this research is basically a qualitative one. In the concluding chapter the researcher finds that Islamic economics could grow to become more social, more so through the growth of the IVES. However, a steady growth of the sector is not enough to actualize HES noticeably in Malaysian contexts. A more robust growth rate in the sector is conditional to decisive government interventions that favor the growth of the IVES. / 博士(グローバル社会研究) / Doctor of Philosophy in Global Society Studies / 同志社大学 / Doshisha University
