Bangladesh economy has experienced some stable growths with regard to major macroeconomic indicators, significant progress in social development indicators, rural infrastructure, investment in industrial agricultural sector, and poverty alleviation since the 1990s. Bangladesh has made major strides in its human development index (HDI), population growth rate achieved to 1.3%, gross domestic product (GDP) over the last five years achieved more than 5% growth consecutively; as a result, it mooted the Brazil, Russia, India, China (BRIC) successors, otherwise known as the Next-11. The success has come through the miracle activities of micro finance (MF: Grameen Bank and non-governmental organizations (NGOs)), remittance from migrant worker (RMW), and export of readymade garment (ERMG) products. These three (MF, RMW, and ERMG) as the "prime powers" or engines have been achieving to "bottom up" of social economic development. This paper reviews aspects of economic development in Bangladesh, analyzes three prime powers, and tries to find out a development pattern, vis-a-vis construct Bangladesh economic development model or BED model. Finally, this paper examines Bangladesh's development experience in light of the BED model. It has recognized MF model for poverty alleviation in the worldwide. 展开更多
