As we can see, there is a significant correlation between the branch of industry including energy and total production, whereas the evolution of this industry depends on the final result of the production. Therefore, these two factors can be related. Between industry, including energy and total production there is a direct and linear in shape.

The third BRANCH is represented by the field of constructions. As we can see from the table in front, the field of constructions has known an important incresse after 200. The reference year, in which the correlation between the two factors is the most high, is 2008, when the total value of production is 458535.5.The evolution of BRANCH 3 Constructions in Romania during 1990-2012 is graphicaly represented as:

Another important branch in corelation with the total production is represented by trade, repair of motor vehicles and motorcycles; transport and storage; hotels and restaurants; information and communications. The period analised is 1990-2012, and we can observe that the correlation between the two indicators is significant for 2008 and 2009, because the BRANCH evolution depends on the total production.The evolution of BRANCH 4 trade, repair of motor vehicles and motorcycles; transport and storage; hotels and restaurants; information and communications in Romania during 1990-2012

BRANCH 5 - financial intermediation and insurance; real estate has an important role in influencing the total production. Between the two indicators there is a direct and linear in shape. As we can see from the table above, the evolution of financial intermediation and insurance; real estate is more considerable starting with 2010 until 2012. The financial intermediation and insurance; real estate field recorded values on rise during this period, who caused the increased of total production.The evolution of BRANCH 5 financial intermediation and insurance; real estate in Romania, during 1990-2012

The correlation between BRANCH 6 other activities and services and the total production highlights that the evolution of two indicators can be related. And from the analysis using software Eviews we can establish that the correlation is significant for the period 2008-2012 when as other activities and services register values increasing to establish and increase the total production.The evolution of BRANCH 6 (other services and services) in Romania during 1990-2012
