Regression Analysis of the Automobile Road Construction Efficiency in Pripyatsky Polesie (Republic of Belarus)
The article describes the expediency stages of investing in construction, including highways, provides a characteristic of the main indicators for a comparative assessment of design options. The components of investment efficiency and indicators that ensure the reduction of transport costs are presented. The factors that normalize the rate of return are presented, such as: the average real deposit or lending rate; alternative rate of return on other potentially possible forms of investment; rates of return for current production activities; inflation rate; risk reward, etc. The calculation of the investment construction efficiency of a technical category road to replace the existing unpaved road of the V category in Pripyat Polesie, the need for which is associated with the construction of a mining and processing complex for the production of potassium chloride in the area of Petrikov, where development began in 2014 - running of the Petrikovskoye field, which is an important raw material base for supporting and increasing the production capacity of JSC ,,Belaruskali“ and for the Republic of Belarus. Calculations have shown that the construction of the highway is effective, since the capital investment will pay off in 6 years. To identify the real influence of factors on obtaining the final result, a regression analysis was performed using elements of statistics, which determined indicators that have a significant impact on the efficiency of construction, which include: socio-economic effect (3t), reduction of losses in social sphere (AC;"0), the effect of reducing the time spent on the way of passengers (AC^).
