Financial risks of the COVID-19 pandemic and corporate social responsibility for sustainable development in the post-COVID economy

The source of data for the study is the Numbeo quality of life statistics (2021):
Numbeo. 2021. Quality of life index, by country: 2012-2021 (mid-year). URL: https://www.numbeo.com/quality-of-life/rankings_by_country.jsp?title=2021-mid

File 1 contains statistics of Numbeo (2021) for 2012-2021. (mid-year):
- Purchasing power index (x1) 4
- Cost of living index (x2);
- property price to income ratio (x3);
- Safety index (y1);
- Health care index (y2);
- Traffic commute time index (y3);
- Pollution index (y4);
- Climate index (y5).
The growth of indicators is also estimated: 2019/2018, 2020/2019, 2021/2020.

In file 2, the competitiveness of indicators is determined, the arithmetic mean, standard deviation in 2021 is calculated and forecasts of changes in indicators (based on arithmetic means and standard deviations) are made, histograms of their normal distribution are constructed.

In file 3, the dependence of each of the indicators y on the set of indicators x was determined by the method of regression analysis.

本研究的数据来源为Numbeo 2021年生活质量统计数据集：

文件1收录了2012-2021年（年中时段）的Numbeo 2021年统计指标，具体包括：
- 购买力指数（x₁）4
- 生活成本指数（x₂）；
- 房价收入比（x₃）；
- 安全指数（y₁）；
- 医疗保健指数（y₂）；
- 通勤时间指数（y₃）；
- 污染指数（y₄）；
- 气候指数（y₅）。
此外，本文件还估算了各指标的同比增长率：2019年相较2018年、2020年相较2019年、2021年相较2020年。

文件2中，我们对各指标的竞争力进行了测算，计算了2021年各指标的算术平均值与标准差，并基于上述均值和标准差完成了指标变化预测，同时绘制了各指标正态分布的直方图。

文件3通过回归分析法，确立了各y类指标相对于x类指标集合的依存关系。
