Abstract: The COVID-19 spread rapidly to the whole country, which had a great impact on our economic and social development. Digital economy investment plays a key role in the development of economy because of its obvious effects of driving economic growth in a short period. In the short run, the COVID-19 will make an impact on the whole digital economy investment, industrial digital transformation investment, private investment and foreign direct investment. In the long run, the impact of the COVID-19 on digital economy investment is not sustainable. Once the COVID-19 is brought under control, the scale of digital economy investment will continue to expand, and new models and new forms of business, industrial digital transformation and digital governance will become the hot areas of investment. So the government should help enterprises to tide over the difficulties which are greatly affected by the COVID-19 using its financial measures. In the long run, we should strengthen investment guidance in the digital economy, activate private investment in the digital economy, and optimize the investment environment in the digital economy.

Key words: COVID-19, digital economy investment, short-term effects, long-term effects
