Evaluación del comportamiento de los indicadores de productividad y rentabilidad financiera del sector petróleo y gas en Colombia mediante el análisis discriminante

Abstract

This research paper presents the results of the behavior of productivity and profitability indicators in the oil and gas sector in Colombia in the years 2008 and 2010 by means of discriminant analysis. Initially there is an analysis of the sector and a theoretical review of the financial management assessment, strategic leverage, stakeholders, agency theory, productivity and profitability indicators and basic concepts of discriminant analysis. In the methodology used, productivity and profitability indicators were calculated for 116 companies in the oil and gas sector from the financial statements in the periods of study. Then, the discriminant analysis technique was used to explain the belonging and discrimination of the indicators studied. From the discriminant function and the means obtained it can be concluded that the analyzed indicators do not present significant differences, which shows a period of stagnation in the periods studied. With the research work it was concluded, by discriminant analysis, that there is a significant difference just for the indicator gross margin. The discriminant function model allows an effective classification of 57.3%.
