英文摘要：
We extend the exploration regarding dynamical approach of macroeconomic variables by tackling systematically expenditure using Statistical Physics models (for the first time to the best of our knowledge). Also, using polynomial distribution which characterizes the behavior of dynamical systems in certain situations, we extend also our analysis to mean income data from the UK that span for a time interval of 35 years. We find that most of the values for coefficient of determination obtained from fitting the data from consecutive years analysis to be above 80%. We used for our analysis first degree polynomial, but higher degree polynomials and longer time intervals between the years considered can dramatically increase goodness of the fit. As this methodology was applied successfully to income and wealth, we can conclude that macroeconomic systems can be treated similarly to dynamic systems from Physics. Subsequently, the analysis could be extended to other macroeconomic indicators.

中文摘要：
我们通过使用统计物理模型系统地解决支出问题（据我们所知，这是第一次），扩展了关于宏观经济变量动态方法的探索。此外，我们还利用多项式分布来表征动力系统在某些情况下的行为，将我们的分析扩展到英国35年的平均收入数据。我们发现，通过拟合连续几年的分析数据得出的大多数确定系数值都在80%以上。我们在分析中使用了一次多项式，但高次多项式和考虑的年份之间的较长时间间隔可以显著提高拟合优度。随着这一方法成功地应用于收入和财富，我们可以得出结论，宏观经济系统可以类似于物理学中的动态系统。随后，该分析可以扩展到其他宏观经济指标。
