The above table presents data that has been analyzed in this paper to determine the profitability of companies on the Sci-Tech Innovation Board during the COVID-19 pandemic. The findings indicate that the profitability of these companies has significantly decreased, with the net profit margin even becoming negative in 2020 when the pandemic was at its worst.

Despite this, the study also shows that the profitability of companies on the Sci-Tech Innovation Board is relatively stable in the long-term. Excluding the 2020 data, which was heavily impacted by the pandemic, the four major profitability indicators of these companies are consistent, indicating that they are not adequately equipped to deal with force majeure risks. Therefore, it is necessary for these companies to adjust their development strategies and improve their risk coping ability.

Furthermore, the study found that the return on net assets index is consistently higher than the return on total assets index, indicating that the total input-output efficiency of these companies is not optimal. As such, companies on the Science and Technology Innovation Board should focus on revitalizing non-performing and idle assets to enhance their profit potential.

In conclusion, this paper highlights the need for companies on the Sci-Tech Innovation Board to adapt to the challenges presented by the COVID-19 pandemic and improve their overall profitability. This can be achieved by developing effective risk management strategies and optimizing their use of assets to maximize returns
