The US is still out in front of global competitors when it comes to innovation (革新), but American universities—where new ideas often spread—have reason to look over their shoulders．
That's especially true for technologies like 5G phone networks and artificial intelligence.In President Donald Trump's opinion, they're exactly the fields where the US has to lead—and also the ones where Asia, especially China, is catching up.Universities from China get more patents than their US peers in wireless communications, according to rearch firm GreyB Services.In AI, 17 of the top 20 universities and public rearch organizations are in China, with the Chine Academy of Sciences topping the list, says the World Intellectual Property Organization in Geneva.
There's a special place for universities in the development of science.Universities educate future scientists and can be incubators (孵化器) for pieinthesky ideas, some of which turn out to be gamechangers.The list ranges from Google's arch engine to DNA technology that's behind a whole industry of genemanipulating (基因编辑) treatments.
However, government aids to universities haven't been growing for more than a decade, meaning they've declined in real terms and as a share of the economy, leading to the cost increa for universities and meanwhile somehow discouraging the teaching staff from putting all their hearts into their scientific rearch.
“If you look at the federal dollars, they've not really changed considerably，” says Stephen Susalka, head of AUTM, a technology transfer association who members include 800 universities.“Other countries are catching up.We can't be satisfied with what we have achieved.”
