This study is an attempt to analyse the factors responsible for export performance involving both supply inelasticity hypothesis and demand deficiency approach of trade. The study follows some previous empirical work (Lewis 1980; Riedel 1988) in this area. World demand (developed/developing market economy’s demand) and relative export price affect export performance from the demand side while the variables like effective rate of assistance (ERA), exchange rate, non-price factor (process of learning), government policies, export diversification are considered to be supply side influences on export growth. The paper demonstrates that world demand is an important determinant of export performance. The competitiveness of Bangladesh exports in the world market may be influenced by exchange rate trade-weighted exchange rate and effective rate of assistance are found to be significantly positive. The positive and significant coefficient of dummy variable in the exchange rate indicates that devaluation has some positive effect on the export performance of Bangladesh. The coefficient of efficiency index is found to be positive in most cases. There is a strong indication of positive effect of non-price factors on export growth. Lastly, the export performance of Bangladesh has been found to be associated with greater commodity diversification of exports. Bangladesh tends to maintain its greater share of world exports when the international demand changes towards commodity composition.
