Formation of Sustainable Competitiveness of Enterprises on Soils of Different Quality

Abstract

The objective of this paper is to highlight the results of assessing the impact of soil quality on the sustainable competitiveness of agricultural enterprises in Ukraine. The general hypothesis of the research is based on the assumption of available positive relations between soil quality and sustainable competitiveness of enterprises. The average content of humus is taken as an integral index of soil quality. The authors used correlation analysis (for determine the relationship density between content of humus and subindexes of sustainable competitiveness), econometric modeling (for study of the dependence between content of humus and subindexes of sustainable competitiveness), economic-statistical (for evaluation and analysis of the impact of content of humus on the sustainable competitiveness), abstract-and-logical (for theoretical generalization and analysis of the research results), and graphical (for the visual representation of the revealed dependencies). To receive the results, the statistical software package STATISTICA is used. The obtained results prove the hypothesis of a positive relationship between content of humus and sustainable competitiveness only in the area of sufficient moisture. For example, the research reveals a high direct correlation relation (r = 0.735) between the subindexes of competitiveness by the yield of cereals and content of humus in soil in Chernihiv region. For the first time, one- and two-factor linear and quadratic econometric models were developed, which made it possible to carry out quantitative estimation of the impact of content of humus on the formation of sustainable competitiveness.
