WASHINGTON (BLOOMBERG) - South Korea returned to first place in the latest Bloomberg Innovation Index, while the US dropped out of a top 10 that features a cluster of European countries.
South Korea regained the crown from Germany, which dropped to fourth place. The Asian nation has now topped the index for seven of the nine years that it has been published.
Singapore and Switzerland each moved up one spot to rank second and third.
The Bloomberg index analyses dozens of criteria using seven equally weighted metrics, including research and development (R&D) spending, manufacturing capability and concentration of high-tech public companies.
The 2021 rankings reflect a world where the fight against Covid-19 has brought innovation to the fore - from government efforts to contain the pandemic to the digital infrastructure that has allowed economies to work through it, and the race to develop vaccines that can end it.
"In the year of Covid-19 and facing the urgency of climate change, the importance of innovation fundamentals only increases," said Citigroup global chief economist Catherine Mann.
"Innovation is often measured by new ideas, new products and new services," she said, but it is their "diffusion and adoption" that is the real metric of success.
Much of the Bloomberg data comes from before the virus crisis. Still, it is notable that many countries high on the index - like South Korea, Germany and Israel - have been world leaders in some areas of fighting the pandemic, whether it is contact tracing or speedy vaccination. American names like Zoom Video Communications or vaccine-maker Pfizer are among the past year's emblems of innovation, reflecting the United States' top ranking for density of high-tech firms.
The pandemic has also spotlighted a different kind of breakthrough, one that has more to do with policy and organisation than technology or research, according to Nobel Prize-winning economist Paul Romer.
"We should recognise that the available metrics miss important dimensions of innovation," said Dr Romer, a professor at New York University's Stern School of Business. "Officials in Wuhan showed for the first time that in a couple of weeks, it is feasible to test 10 million residents of a city for the coronavirus. This was a very important public health innovation."
'Have a future'
South Korea's return to the top spot is mainly due to an increase in patent activity, where it ranks top, alongside a strong performance in R&D and manufacturing.
There is near-total agreement in South Korea that "R&D is essential" to having a future, said business management professor Lee Kyung-mook of Seoul National University.
"It's sandwiched between more developed nations, which still outperform... in technology, and China that is catching up fast, relying on lower labour costs."
Second-placed Singapore, which has been allocating Budget funds to help workers and companies transition to a digital economy, also scores high for manufacturing - and its globally competitive universities put it top of the tertiary education gauge.
Switzerland, a leader in financial and biological technology, ranks near the top in both of the index's research categories.
Germany's loss of the crown follows a warning two years ago by Bayerische Landesbank chief economist Juergen Michels, who said the country lacked skilled workers and a proper strategy for next-generation technology.
As the two biggest economies, the US and China account for much of the world's innovation. But both saw their rankings decline this year.
'Will take time'
The US, which topped the first Bloomberg Innovation Index in 2013, dropped two places to 11th. In a report last year, the National Science Board found that "where once the US was the uncontested leader in science and engineering, we are now playing a less dominant role".
The country scores badly in higher education, even though US universities are world-famous. That underperformance was likely made worse by obstacles to foreign students, who are usually prominent in science and technology classes - first due to the Trump administration's visa policies, and later to the pandemic.
President Joe Biden ran on a promise to reinvigorate US manufacturing with a US$300 billion (S$399 billion) investment in R&D and breakthrough technologies, a policy he labelled "Innovate in America".
Mr Sung Won Sohn, an economist at Loyola Marymount University in Los Angeles, says the US is still in the vanguard - but nowadays, its innovations tend to come from smaller companies, and take longer to reach the consumer.
"There are a lot of new ideas from many start-ups," he said. "It will take time for the ideas to be translated into marketable products."
China, which fell one place to 16th in the 2021 index, is locked in a battle with the US over key aspects of innovation policy.
The Chinese economy has gained ground on rivals with a faster recovery from the coronavirus slump. But its slippage in the index reflects longer-term issues such as the erosion of value-added manufacturing - where regional competitors like Vietnam and Bangladesh have gained ground.
Other gainers in this year's index include India, which climbed back into the top 50 for the first time since 2016, and Uruguay, which qualified for the first time. Algeria and Argentina were among the countries that fell furthest.
The ranking process began with more than 200 economies, scored on a scale of 0 to 100 in seven equally weighted categories. Nations that did not report data for at least six categories were eliminated, trimming the total list to 111. Bloomberg publishes the top 60 economies.
