## 3 Results  
The first results of this research refer to descriptive statistics for each company and each variable from the study. Table 3 presents the descriptive statistics (presented as mean \(\pm\) standard deviation (minimum value \(-\) maximum value) in Romanian lei current prices) for the economic performance indicators, including the yield indicators for each company. Since there are some differences between the companies, as shown in Tables 1 and 2, we calculated the efficiency per employee, which is shown in Table 3, to obtain a better comparison of each company's performance. The differences are obvious. The turnover of company A is under the value of Company B per employee, and the net profit per employee is superior. In addition, debts per employee for Company A is lower than that for Company B. In Figure 2a-f, the evolutions and trends of the main economic indicators of the researched companies are comparatively described. \begin{table}

Table 3: Descriptive statistics for the economic performance indicators (in lei current prices). It can be seen that the evolutions of the companies are different during the five years, except for two indicators, i.e., own capital (with a steep trend for Company B and a smooth trend for Company A) and the number of employees, both with an ascending trend. For example, the turnover for Company B has a descending trend compared with that of Company A, which has an ascending trend. More interestingly, the evolution of net profit has a positive trend for Company A and a negative trend for Company B, while debts and fixed assets have opposite evolutions, i.e., for Company B debts and fixed assets increase, while for Company A they decrease with positive significance, of course, for Company A by maintaining the good evolution for this company. Starting with the above-mentioned results, we applied an ANOVA test to compare if the means were statistically different between the companies; the results are presented in Table 4.  
Figure 2: The evolutions and trends of the main economic indicators of the researched companies. The results of the ANOVA test indicate statistical differences between means (\(p\)-value <0.05) for the following: turnover, own capital, number of employees, debts, and fixed assets.
