With frequent climate change related disaster shocks and a huge burden of refugees from neighbor country’s conflict, Bangladesh needs to formulate effective strategies to support its most prospective sectors for ensuring sustainable development. This paper aims at disentangling the process of economic growth in Bangladesh to identify some prospective accelerating sectors, which could achieve constant economic growth with proper policy support. Using a modification of traditional structural decomposition analysis (SDA), we identify some prospective growth sectors in the Bangladesh economy. We have found labor intensive manufacturing and some high value added service sectors as key sectors for growth in Bangladesh. We compare the existing economic structure of Bangladesh with five other Asian lower income developing countries (LIDCs) and found all other countries have mostly similar economic structure, except Vietnam. Our analysis showed Bangladesh is mainly dependent on the textiles and food sectors in manufacturing and construction, real estate and inland transport sectors in service, for its quick growth. Most importantly, we found some new manufacturing sectors, such as basic metal and machineries, NEC, and recycling sectors, are constantly growing over the last decade, using our technique. Proper policy support to these high potential emerging sectors could help Bangladesh achieve the sustainable development goals (SDGs) of ensuring economic growth and sustainable development through promoting industrial diversification.
