أثر الاستثمار في التعليم الزراعي على نمو الإنتاجية الكلية للعوامل بالقطاع الزراعي المصري (باستخدام نموذج تصحيح الخطأ)‎

الملخص EN

The research aims to study the impact of investment in agricultural education on the growth of the total factor productivity (TFP) in the Egyptian agricultural sector in the short and long term during the period of 1995-2021.

the research was based on the unit root test, the cointegration test, and the error correction model (ECM).

the study model included the TFP in the Egyptian agricultural sector as a dependent variable, while the independent variables were total fixed capital formation as an indicator of technological development, total spending on agricultural education as an indicator of investment in agricultural education, numbers of graduates of agricultural colleges and institutes, and numbers of graduates of agricultural schools, both as an indicator for agricultural education.

the results of ADF test indicated that the time series for all variables are not stationary at their level, but they are all stationary at their first differences.

the results of the co-integration test also indicated that there is co-integration between the set of variables under study, which indicates the existence of a linear combination between those variables, and this result confirms the possibility of a long-term equilibrium relationship between these variables.

it was also found that the model does not suffer from the autocorrelation problem or the difference of variance problem.

the results of ECM indicated that the value of the error correction limit coefficient (ECMt-1) amounted to 0.311, meaning that about 31.1% of this imbalance is modified in the next period, and this means that the period of adjustment of the TFP towards the equilibrium on the long-term is about 3.22 years, which is somewhat slow, as shown by the elasticity of the independent variables, the importance of investment in agricultural education) in affecting the TFP in the Egyptian agricultural sector, as it is clear that the number of agricultural school graduates has a greater impact than the numbers of graduates of agricultural colleges.
