Abstract. The article is devoted to modeling mechanism for evaluation the labor contribution of Russian employees of public and private enterprises in the construction sector based on an analysis of current problems in the remuneration of the government. There was also taken into account the state of motivation system and job satisfaction of human resources in the executive authorities in the subject of Russian Federation (on an example of the Yamalo-Nenets Autonomous Okrug -YaNAO). The survey was dedicated to revealing preferences of civil servants in matters of career growth, professional development. On the basis of the quota survey of civil servants using absentee (dispenser) survey, conducted in July-September 2015 in Yamalo-Nenets, the following conclusions were formulated. The study has found that enrollment in the personnel reserve is not an effective measure to motivate public servants since it functions mostly just formally. Of particular importance are such working conditions as "remuneration dependence on the actual results" and "Personal responsibility for specific areas of activity", which is directly linked with the possibility to receive appropriate remuneration. Authors propose an integral indicator for assessing labor contribution of an employee of public and private enterprises of the construction sector in order to improve financial motivation and increase the level of interest, which is based on the principles of economic and mathematical modeling.
