In empirical literature GDP is also one of the valid determinants, as many studies found positive and significant impact of this variable on exports e.g. Ekanayake (1999), but there are studies which found insignificant impact of GDP growth rate on exports as Agasha (2007) in Uganda found insignificant impact of GDP on export. The result of the present study for this variable (GDP) is also significant with positive sign. High level of production can be utilized at domestic and international level at the same time. Majority of developing countries including Pakistan have relative advantages for agriculture goods. They can exhaust benefits of lower cost production by export growth policies. Moreover, large size of GDP creates environments for investment decisions. However, two important variables have been found statistically insignificant but shows expected positive relationship.
