(JW Insights) Apr 17 -- The private investment gap between China and the US in the artificial intelligence(AI) field widened in 2022, with the US leading the world, according to the recently released Stanford University 2023 AI Index Report. 

The $47.4 billion invested in the US was roughly 3.5 times the amount invested in the next highest country, China ($13.4 billion). Compared with 3.05 times in 2021 and 2.38 times in 2020, the gap has further widened.

The report provides a panoramic review of the progress in the field of AI in 2022, covering hot topics such as AI research, ethical challenges, policy, public opinion, and business.

In terms of the publication of papers and patent applications, China’s academic and industrial circles performed strongly.

The report also said that Chinese citizens are among those who feel the most positively about AI products and services. In a survey, 78% of Chinese respondents (the highest proportion of surveyed countries) agreed with the statement that products and services using AI have more benefits than drawbacks.

The report also shows that the global investment in AI in 2022 totaled about $189 billion. The VC investment in start-ups in the field reached $91 billion, both are the second highest level in history, only less than the scale in 2021.
