The Influence of Investments on the Technical-Economic Performance of the Agricultural Sector in Romania

The article presents the results of a quantitative analysis, of dynamic structural type, regarding the impact that the investments in the agricultural sector have on the performances of this sector. The numerical evaluation of the impact of investments on the performances of the agricultural sector was based on an econometric approach, respectively on the use of simple linear regression models. Within these econometric models, the explanatory variable was represented by the investments in the agricultural sector, and as dependent variables were considered, successively, three performance indicators specific to the agricultural sector: the gross domestic product, the added value and the number of machines. The data used in the analysis and for estimating the econometric models have as source the database of the National Institute of Statistics. The obtained results highlight the fact that the investments in the agricultural sector overwhelmingly influence the performances of the agricultural sector, measured through the three performance indicators. Indeed, the correlation coefficients between the investments and the three performance indicators have very high values, higher than 0.75. Also, in the case of all the three estimated econometric models, the multiple determination ratio has very high values, over 0.75, which means that over 75% of the variant of the three performance indicators are formed under the impact of investments.
