Abstract

The main objective of this research is to try to improve the
competitiveness and increase export efficiency of Egyptian grapes exports
during the period (0222-0248). To achieve this objective, the following subobjectives were studied: 4- Studying the relative importance of grape exports
for fruit exports, agricultural exports, 0 - The study of the development of the
quantity, value and export prices of grape exports, 5 - Measuring the indicators
of the export efficiency of Egyptian exports of grapes, (Efficiency of the
performance of export operations - The degree of economic openness - The
coefficient of comparative advantage phenomenon - Instability coefficient -
Gini coefficient of quantity and value of exports to (1) Estimating the external
demand for Egyptian grape exports using the market participation model. The
research relied on the published and unpublished secondary data issued by the
Central Agency for Public Mobilization and Statistics, the computer database
of the system, Agriculture, the Food and Agriculture Organization of the
United Nations (FAO), foreign trade publications, and some previous studies
in this field. To achieve the objectives of the research, statistical, economic
and statistical methods of analysis were used by estimating general trend
patterns Linear model for each of the cultivated area, production and
productivity, quantity and value and export prices, and adopted economic
analysis at the expense of some indicators which the most important of the
instability coefficient, the calculation of the concentration geographical
coefficient (Gini) coefficient, was used as a form of market participation to
estimate the demand for grape exports function.
The main findings of the study were: The percentage of Egypt's
exports of grapes from fruit exports continued to rise. The relative importance
of this period reached about 402031. The lowest value of the relative
importance in 0224 was 22091. The percentage of Egypt's exports of grapes
for agricultural exports increased continuously. The relative importance of this
period was about 12901. The relative importance of this year was 22081. The
relative importance in 0229 was 402811. Also, the percentage of Egypt's
exports of grapes for total exports in Irvine The relative importance of this
period was about 2191. The lowest value for the relative importance in 0224
was 22251 and the relative importance of 0248 was 424981. The estimation of
export efficiency indicators for grapes during the study period shows that the
degree of economic openness The efficiency of export operations for grapes
was estimated at 22231 for the average period, and the maximum efficiency rate in 0228 was estimated at about 2242821, while the percentage of the
grapes was 2228791 for the average period, reaching a maximum of 2204901
in 0228, While the lowest rate of efficiency in 0222 was estimated at about
2222401, and it turned out that Mato The coefficient of competitiveness of
Egyptian exports of grapes during the study period was 1245 and its value
ranged between a minimum of 0241 in 0240 and a maximum of 0248 in 0248.
The results of the estimation of the demand function using the market
participation model showed that the value of the regression coefficient The
estimated model for the State of Kuwait and Italy of the UAE was -42425, -
22491, -22405. This confirms an inverse relationship between the relative price
of imports and the market share of grapes. This is consistent with the
economic theory. The price elasticity of the same countries is -2254, -2241,
2248 (Inelastic demand), ie, the higher the relative price of exports, the lower
the In the market share of grape exports. This means that there is a possibility
of increasing the export price of Kuwait, Italy and the UAE, thus increasing
the export yield of grapes, while the results in the same table showed that the
regression coefficient in the estimated model for the UK and Belgium was
22421, 22103 This confirms the existence of a positive relationship between
the relative price of imports and the market share of grapes, which may be due
to the non-saturation of the markets of the grapes and the increase in domestic
demand
