Abstract
Abstract The primary exports in general may expose to several problems in developing countries. One of these problems is the instability state in exports earnings, deteriorating the rates of commercial exchange, and slowdown external demand. Many views verified the effect of these problems in the economic growth. The current paper aims to study this effect on a sample of non-petroleum developing countries from 1985 – 2004. The study also hypothesized that the instability and deterioration of commercial exchange and slowdown external demand have negative impact on the economic growth. A metrical economic model has been proposed to estimate the variables. The paper consisted of three aspects: the first was theoretical to show the relation among these variables and economic growth. The second was to refer to the measurements used to measure these problems. The third one estimated the effect of problems of economic growth. The conclusions recorded very accurate results in all economic, metrical and statistical indicators - in that- the instability and deteriorating the economic growth, deteriorating the rates of commercial exchange, and slowdown external demand have negative effects on the economic growth. This result comes with the theoretical aspect and promoting the hypothesis. .
