Abstract

The research subject is the analysis of the impact of the value of realized investments in new fixed assets on the gross domestic product (GDP) of Serbia in the period from 2012 to 2021. The research was conducted with the aim of determining which economic activity, according to the value of realized investments, contributes the most to the creation of the value of Serbia’s GDP. The defined goal was realized by applying the multiple regression method, and the starting model contained the value of realized investments in four activities, which are: manufacturing; electricity, gas, steam and air conditioning supply; transportation and storage; agriculture, forestry and fishing. The occurrence of multicollinearity between independent variables was checked by the tolerance coefficient, VIF coefficients and Eigen values, and their values indicate the presence of weak multicollinearity, which is a consequence of the impact of realized investments in agriculture, forestry and fishing. The result of the set regression model shows that the greatest contribution to the creation of Serbia’s GDP is made by the realized investment value in the electricity, gas, steam and air conditioning supply (Standardized Beta Coefficients 0.687, Sig. = 0.012).
新固定资产已实现投资对塞尔维亚国内生产总值的影响
研究课题是分析2012 - 2021年塞尔维亚新增固定资产已实现投资价值对国内生产总值(GDP)的影响。进行这项研究的目的是,根据已实现投资的价值,确定哪些经济活动对创造塞尔维亚国内总产值的价值贡献最大。运用多元回归方法实现了所定义的目标,初始模型包含四个活动的已实现投资价值,这四个活动是:制造;电力、燃气、蒸汽和空调供应;运输和储存;农业、林业和渔业。通过容差系数、VIF系数和特征值检验自变量之间是否存在多重共线性,它们的值表明存在弱多重共线性,这是农业、林业和渔业实现投资影响的结果。集合回归模型的结果表明,塞尔维亚在电力、燃气、蒸汽和空调供应方面实现的投资价值对创造GDP的贡献最大(标准化贝塔系数0.687,Sig. = 0.012)。
