The main objective of this paper is to identify the features and the development of Libyan foreign agricultural trade by addressing the following objectives: (1) studying and analyzing of the Libyan foreign agricultural trade structure, (2) calculate the efficiency of Libyan foreign agricultural trade standards. Descriptive and theoretical statistical analysis has been used to achieve the objectives of this paper and to access to the results that serve the objectives of the study. A review of the features and the evolution of Libyan foreign agricultural trade showed increasing the gap value of the Libyan agricultural trade balance from approximately 360.4 million dinars in 1991 to about 2757 million dinars in 2010 with an annual growth rate of about 13% at 0.01 level of significance. A review of the results of indicators of Libyan foreign agricultural trade efficiency showed decreasing of these indicators during the second period (2001- 2010) compared with the first period (1991- 2000). These indicators consisted in the following: average per capita from the Libyan foreign agricultural trade, the rate of Libyan agricultural exports coverage to Libyan agricultural imports, rate the performance of Libyan foreign agricultural trade sector and finally average propensity to agricultural import medium and the tendency for agricultural export. But for the indicator of the rate of Libyan agricultural economic dependency to the outside world, it shows increasing this indicator during the second period (2001- 2010) compared with the first period (1991- 2000) .It also turns out that the Libyan economy is subject to the phenomenon of instability in foreign agricultural trade, which could lead to a negative signal to the values ​​of the tendency emergence of marginal agricultural export and marginal propensity to agricultural import for some years, and then there will be difficulty to calculate geometric mean of the values ​​of this tendency, is to overcome this phenomenon in this study by the marginal propensity account to find the relationship of simple regression between each of the national agricultural income as an independent variable and value of foreign agricultural trade (or the value of Libyan agricultural exports or imports) as dependent variable in the model of double logarithm, which indicate that decreasing value of agricultural export coefficient during the second period (2001-2010) compare with the first period (1991-2000), this result explains that Libyan economy direction to raise agricultural imports during second period (2001-2010) compare with the first period (1991-2000).
