Trade openness and export promotion policies such as export expansion grants are the furthermost competent yardstick for measuring growth and development, approved by various countries since 1970s. Looking at the Nigeria economy whose depends almost largely on external trade is inclusive. Therefore, this analysis explores the effects of trade openness and export expansion grants on Nigerian economy using annual data from 1986-2019. This analysis makes use of coefficient covariance metrics, stability leverage plots and pairwise granger causality and quantile regression to portray the impact of trade openness and export expansion grants on Nigerian economic growth. The outcomes confirm that, there was a positive relationship between trade openness (TOPN) and economic growth (GDPR) in the first and last quantiles (seventh) quantile while the remaining quantiles has negative effect on GDP growth rate of Nigeria and were statistically insignificant during the study era. While the coefficients of export expansion grants (EEXG) have positive effect on GDP growth rate of Nigeria in all quantiles but statistically significant only in sixth as well seventh quantile. Also, the result of pairwise granger causality showed strong bi-directional causality between trade openness and GDPR at 5% level of significance as well as uni-directional causality running from GDPR to export expansion grants. Therefore, it recommended that, Nigerian government should adjust the structure of its trade through concentrating on high value-added products instead of exporting semi-finished goods as well by given more support to domestic industries (such as subsidies, tax holiday, more export expansion grants) to compete internationally. Also, government should maintain stable exchange rate as well policies through effective monetary policies that would reduce inflation rate in the economy in order to attain Nigeria's Economic Recovery and Growth Plan which is in line with SDGs goal of 2023 in Nigeria.
