Analysis has shown that as domestic companies introduce artificial intelligence (AI), the proportion of low-skilled workforce is decreasing and the proportion of high-skilled workforce is increasing. However, there are concerns that the gap by company size may widen as the introduction of AI is focused on businesses with large financial and technological investment capacity, especially large corporations and the public sector. According to the ‘Exploratory analysis of the status and impact of AI adoption in businesses’ report published by the Korea Labor Institute on the 25th, the AI ​​adoption rate of domestic companies with 30 or more employees was 5% as of the end of 2023. Considering that it was only 0.03% in 2015 and 1.5% in 2022, the speed of adoption has accelerated since the spread of generative AI. The larger the company, the higher the adoption rate. The AI ​​adoption rate for businesses with 30 to 99 employees was 3.5%, but for businesses with 100 to 299 employees, it was 8.7%, for those with 300 to 499 employees, it was 12.4%, and for those with 500 or more employees, it was 16.9%. By financial size, the average assets of companies that adopted AI were 2 trillion won, which was 3.1 times that of companies that did not adopt AI (677.9 billion won). By corporate affiliation, there are corporate groups with mutual investment restrictions (assets of 10 trillion won)
