| Abstract | ||||
| The research aims to estimate the supply response functions for the sugar beet crop in Egypt by studying the variables associated with estimating the supply response for the sugar beet crop, which include the cultivated area, productivity, total production, agricultural price, and net return for this crop. It also aims to identify the most important explanatory variables that affect the area. cultivated with the crop under study and the extent of the farmer’s response to expansion or contraction in its cultivation. Derivation of short-run and long-run elasticities is considered a good indicator when making production decisions at the level of both farmers and agricultural policy. To estimate some of the criteria for measuring its economic efficiency, the research relied on descriptive and quantitative analysis methods, where the simple linear regression method was used to estimate the general time trends of some productive and economic phenomena associated with the sugar tree crop in Egypt, in addition to applying Mark Nerloff’s dynamic model to estimate the supply response function. To determine the most important variables affecting the area cultivated with sugar beet crops in Egypt, using multiple regression methods, the research relied on secondary data published from various sources, such as the Agricultural Statistics Bulletin issued by the Central Administration of Agricultural Economics at the Ministry of Agriculture. The results indicated a high amount of annual increase. The consumption of sugar is higher than its counterpart in production, and although production is increasing at an annual growth rate greater than its counterpart in consumption, the average amount of consumption exceeds its counterpart in production, as previous results showed a high growth rate of Egyptian sugar exports, despite the existence of a food gap in sugar and thus. It would have been better to prevent exports to reduce this gap, as it was found that Egypt imports about 41.78% of its sugar consumption from abroad, which is considered food exposure to the outside world. This exposure and dependency on an important commodity such as sugar must be reduced and local alternatives such as increasing crop productivity must be found. Sugar production and raising the efficiency of factories producing sugar and others. It also cleared that the rate of self-sufficiency in sugar increases annually by about 0.97%. Despite this, the percentage of dependence on foreign countries to meet Egypt’s sugar needs increases annually by about 0.32%. This is due to the increasing food gap in sugar, which reached annually, about 2.92%, and it turns out that the farmer is more responsive to the net per-acre return of beets towards expanding the area cultivated with beets, according to the high value of the modified coefficient of determination. | ||||
