Is China Winning the Innovation Race?
Over the past two millennia, Chinese ingenuity has spawned some of humanity's most consequential inventions. Without gunpowder, guns, bombs, and rockets; without paper, printing, and money printed on paper; and without the compass, which enabled ships to navigate the open ocean, modern civilization might never have been born.
Today, a specter is haunting the developed world: Chinese innovation dominance. And the results have been so spectacular that the United States feels its preeminence threatened.
Yet China lapsed into cultural and technological stagnation during the Qing dynasty, just as the Scientific Revolution was transforming Europe. Western colonial incursions and a series of failed rebellions further sapped the Celestial Empire's capacity for innovation. By the mid-20th century, when the Communist triumph led to a devastating famine and years of bloody political turmoil, practically the only intellectual property China could offer for export was Mao's Little Red Book.
After Deng Xiaoping took power in 1978, launching a transition from a rigidly planned economy to a semi-capitalist one, China's factories began pumping out goods for foreign consumption. Still, originality remained a low priority. The phrase "Made in China" came to be synonymous with "cheap knockoff."
Today, however, a specter is haunting the developed world: Chinese innovation dominance. It first wafted into view in 2006, when the government announced an "indigenous innovation" campaign, dedicated to establishing China as a technology powerhouse by 2020—and a global leader by 2050—as part of its Medium- and Long-Term National Plan for Science and Technology Development. Since then, an array of initiatives have sought to unleash what pundits often call the Chinese "tech dragon," whether in individual industries, such as semiconductors or artificial intelligence, or across the board (as with the Made in China 2025 project, inaugurated in 2015). These efforts draw on a well-stocked bureaucratic arsenal: state-directed financing; strategic mergers and acquisitions; competition policies designed to boost domestic companies and hobble foreign rivals; buy-Chinese procurement policies; cash incentives for companies to file patents; subsidies for academic researchers in favored fields.
The results have been spectacular—so much so that the United States feels its preeminence threatened. Voices across the political spectrum are calling for emergency measures, including a clampdown on technology transfers, capital investment, and Chinese students' ability to study abroad. But are the fears driving such proposals justified?
"We've flipped from thinking China is incapable of anything but imitation to thinking China is about to eat our lunch," says Kaiser Kuo, host of the Sinica podcast at supchina.com, who recently returned to the U.S after 20 years in Beijing—the last six as director of international communications for the tech giant Baidu. Like some other veteran China-watchers, Kuo believes neither extreme reflects reality. "We're in as much danger now of overestimating China's innovative capacity," he warns, "as we were a few years ago of underestimating it."
A Lab and Tech-Business Bonanza
By many measures, China's innovation renaissance is mind-boggling. Spending on research and development as a percentage of gross domestic product nearly quadrupled between 1996 and 2016, from .56 percent to 2.1 percent; during the same period, spending in the United States rose by just .3 percentage points, from 2.44 to 2.79 percent of GDP. China is now second only to the U.S. in total R&D spending, accounting for 21 percent of the global total of $2 trillion, according to a report released in January by the National Science Foundation. In 2016, the number of scientific publications from China exceeded those from the U.S. for the first time, by 426,000 to 409,000. Chinese researchers are blazing new trails on the frontiers of cloning, stem cell medicine, gene editing, and quantum computing. Chinese patent applications have soared from 170,000 to nearly 3 million since 2000; the country now files almost as many international patents as the U.S. and Japan, and more than Germany and South Korea. Between 2008 and 2017, two Chinese tech firms—Huawei and ZTE—traded places as the world's top patent filer in six out of nine years.
"China is still in its Star Trek phase, while we're in our Black Mirror phase." Yet there are formidable barriers to China beating America in the innovation race—or even catching up anytime soon.
Accompanying this lab-based ferment is a tech-business bonanza. China's three biggest internet companies, Baidu, Alibaba Group and Tencent Holdings (known collectively as BAT), have become global titans of search, e-commerce, mobile payments, gaming, and social media. Da-Jiang Innovations in Science and Technology (DJI) controls more than 70 percent of the world's commercial drone market. Of the planet's 262 "unicorns" (startups worth more than a billion dollars), about one-third are Chinese. The country attracted $77 billion in venture capital investment between 2014 and 2016, according to Fortune, and is now among the top three markets for VC in emerging technologies including AI, virtual reality, autonomous vehicles, and 3D printing.
These developments have fueled a buoyant techno-optimism in China that contrasts sharply with the darker view increasingly prevalent in the West—in part, perhaps, because China's historic limits on civil liberties have inured the populace to the intrusive implications of, say, facial recognition technology or social-credit software, which are already being used to tighten government control. "China is still in its Star Trek phase, while we're in our Black Mirror phase," Kuo observes. By contrast with Americans' ambivalent attitudes toward Facebook founder Mark Zuckerberg or Amazon's Jeff Bezos, he adds, most Chinese regard tech entrepreneurs like Baidu's Robin Li and Alibaba's Jack Ma as "flat-out heroes."
Yet there are formidable barriers to China beating America in the innovation race—or even catching up anytime soon. Many are catalogued in The Fat Tech Dragon, a 2017 monograph by Scott Kennedy, deputy director of the Freeman Chair in China Studies and director of the Project on Chinese Business and Political Economy at the Center for Strategic and International Studies. Among the obstacles, Kennedy writes, are "an education system that encourages deference to authority and does not prepare students to be creative and take risks, a financial system that disproportionately funnels funds to undeserving state-owned enterprises… and a market structure where profits can be made through a low-margin, high-volume strategy or through political connections."
China's R&D money, Kennedy points out, is mostly showered on the "D": of the $209 billion spent in 2015, only 5 percent went toward basic research, 10.8 percent toward applied research, and a massive 84.2 percent toward development. While fully half of venture capital in the States goes to early-stage startups, the figure for China is under 20 percent; true "angel" investors are scarce. Likewise, only 21 percent of Chinese patents are for original inventions, as opposed to tweaks of existing technologies. Most problematic, the domestic value of patents in China is strikingly low. In 2015, the country's patent licensing generated revenues of just $1.75 billion, compared to $115 billion for IP licensing in the U.S. in 2012 (the most recent year for which data is available). In short, Kennedy concludes, "China may now be a 'large' IP country, but it is still a 'weak' one."
"[The Chinese] are trying very hard to keep the economy from crashing, but it'll happen eventually. Then there will be a major, major contraction."
Anne Stevenson-Yang, co-founder and research director of J Capital Research, and a leading China analyst, sees another potential stumbling block: the government's obsession with neck-snapping GDP growth. "What China does is to determine, 'Our GDP growth will be X,' and then it generates enough investment to create X," Stevenson-Yang explains. To meet those quotas, officials pour money into gigantic construction projects, creating the empty "ghost cities" that litter the countryside, or subsidize industrial production far beyond realistic demand. "It's the ultimate Ponzi-scheme economy," she says, citing as examples the Chinese cellphone and solar industries, which ballooned on state funding, flooded global markets with dirt-cheap products, thrived just long enough to kill off most of their overseas competitors, and then largely collapsed. Such ventures, Stevenson-Yang notes, have driven China's debt load perilously high. "They're trying very hard to keep the economy from crashing, but it'll happen eventually," she predicts. "Then there will be a major, major contraction."
"An Intensifying Race Toward Techno-Nationalism"
The greatest vulnerability of the Chinese innovation boom may be that it still depends heavily on imported IP. "Over the last few years, China has placed its bets on a combination of global knowledge sourcing and indigenous technology development," says Dieter Ernst, a senior fellow at the Centre for International Governance Innovation in Waterloo, Canada, and the East-West Center in Honolulu, who has served as an Asia advisor for the U.N. and the World Bank. Aside from international journals (and, occasionally, industrial espionage), Chinese labs and corporations obtain non-indigenous knowledge in a number of ways: by paying licensing fees; recruiting Chinese scientists and engineers who've studied or worked abroad; hiring professionals from other countries; or acquiring foreign companies. And though enforcement of IP laws has improved markedly in recent years, foreign businesses are often pressured to provide technology transfers in exchange for access to markets.
Many of China's top tech entrepreneurs—including Ma, Li, and Alibaba's Joseph Tsai—are alumni of U.S. universities, and, as Kuo puts it, "big fans of all things American." Unfortunately, however, Americans are ever less likely to be fans of China, thanks largely to that country's sometimes predatory trade practices—and also to what Ernst calls "an intensifying race toward techno-nationalism." With varying degrees of bellicosity and consistency, leaders of both U.S. parties embrace elements of the trend, as do politicians (and voters) across much of Europe. "There's a growing consensus that China is poised to overtake us," says Ernst, "and that we need to design policies to obstruct its rise."
One of the foremost liberal analysts supporting this view is Lee Branstetter, a professor of economics and public policy at Carnegie Mellon University and former senior economist on President Barack Obama's Council of Economic Advisors. "Over the decades, in a systematic and premeditated fashion, the Chinese government and its state-owned enterprises have worked to extract valuable technology from foreign multinationals, with an explicit goal of eventually displacing those leading multinationals with successful Chinese firms in global markets," Branstetter wrote in a 2017 report to the United States Trade Representative. To combat such "forced transfers," he suggested, laws could be passed empowering foreign governments to investigate coercive requests and block any deemed inappropriate—not just those involving military-related or crucial infrastructure technology, which current statutes cover. Branstetter also called for "sharply" curtailing Chinese students' access to Western graduate programs, as a way to "get policymakers' attention in Beijing" and induce them to play fair.
Similar sentiments are taking hold in Congress, where the Foreign Investment Risk Review Modernization Act—aimed at strengthening the process by which the Committee on Foreign Investment in the United States reviews Chinese acquisition of American technologies—is expected to pass with bipartisan support, though its harsher provisions were softened due to objections from Silicon Valley. The Trump Administration announced in May that it would soon take executive action to curb Chinese investments in U.S. tech firms and otherwise limit access to intellectual property. The State Department, meanwhile, imposed a one-year limit on visas for Chinese grad students in high-tech fields.
Ernst argues that such measures are motivated largely by exaggerated notions of China's ability to reach its ambitious goals, and by the political advantages that fearmongering confers. "If you look at AI, chip design and fabrication, robotics, pharmaceuticals, the gap with the U.S. is huge," he says. "Reducing it will take at least 10 or 15 years."
Cracking down on U.S. tech transfers to Chinese companies, Ernst cautions, will deprive U.S. firms of vital investment capital and spur China to retaliate, cutting off access to the nation's gargantuan markets; it will also push China to forge IP deals with more compliant nations, or revert to outright piracy. And restricting student visas, besides harming U.S. universities that depend on Chinese scholars' billions in tuition, will have a "chilling effect on America's ability to attract to researchers and engineers from all countries."
"It's not a zero-sum game. I don't think China is going to eat our lunch. We can sit down and enjoy lunch together."
America's own science and technology community, Ernst adds, considers it crucial to swap ideas with China's fast-growing pool of talent. The 2017 annual meeting of the Palo Alto-based Association for Advancement of Artificial Intelligence, he notes, featured a nearly equal number of papers by researchers in China and the U.S. Organizers postponed the meeting after discovering that the original date coincided with the Chinese New Year.
China's rising influence on the tech world carries upsides as well as downsides, Scott Kennedy observes. The country's successes in e-commerce, he says, "haven't damaged the global internet sector, but have actually been a spur to additional innovation and progress. By contrast, China's success in solar and wind has decimated the global sectors," due to state-mandated overcapacity. "When Chinese firms win through open competition, the outcome is constructive; when they win through industrial policy and protectionism, the outcome is destructive."
The solution, Kennedy and like-minded experts argue, is to discourage protectionism rather than engage in it, adjusting tech-transfer policy just enough to cope with evolving national-security concerns. Instead of trying to squelch China's innovation explosion, they say, the U.S. should seek ways to spread its potential benefits (as happened in previous eras with Japan and South Korea), and increase America's indigenous investments in tech-related research, education, and job training.
"It's not a zero-sum game," says Kaiser Kuo. "I don't think China is going to eat our lunch. We can sit down and enjoy lunch together."
Catching colds may help protect kids from Covid
A common cold virus causes the immune system to produce T cells that also provide protection against SARS-CoV-2, according to new research. The study, published last month in PNAS, shows that this effect is most pronounced in young children. The finding may help explain why most young people who have been exposed to the cold-causing coronavirus have not developed serious cases of COVID-19.
One curiosity stood out in the early days of the COVID-19 pandemic – why were so few kids getting sick. Generally young children and the elderly are the most vulnerable to disease outbreaks, particularly viral infections, either because their immune systems are not fully developed or they are starting to fail.
But solid information on the new infection was so scarce that many public health officials acted on the precautionary principle, assumed a worst-case scenario, and applied the broadest, most restrictive policies to all people to try to contain the coronavirus SARS-CoV-2.
One early thought was that lockdowns worked and kids (ages 6 months to 17 years) simply were not being exposed to the virus. So it was a shock when data started to come in showing that well over half of them carried antibodies to the virus, indicating exposure without getting sick. That trend grew over time and the latest tracking data from the CDC shows that 96.3 percent of kids in the U.S. now carry those antibodies.
Antibodies are relatively quick and easy to measure, but some scientists are exploring whether the reactions of T cells could serve as a more useful measure of immune protection.
But that couldn't be the whole story because antibody protection fades, sometimes as early as a month after exposure and usually within a year. Additionally, SARS-CoV-2 has been spewing out waves of different variants that were more resistant to antibodies generated by their predecessors. The resistance was so significant that over time the FDA withdrew its emergency use authorization for a handful of monoclonal antibodies with earlier approval to treat the infection because they no longer worked.
Antibodies got most of the attention early on because they are part of the first line response of the immune system. Antibodies can bind to viruses and neutralize them, preventing infection. They are relatively quick and easy to measure and even manufacture, but as SARS-CoV-2 showed us, often viruses can quickly evolve to become more resistant to them. Some scientists are exploring whether the reactions of T cells could serve as a more useful measure of immune protection.
Kids, colds and T cells
T cells are part of the immune system that deals with cells once they have become infected. But working with T cells is much more difficult, takes longer, and is more expensive than working with antibodies. So studies often lags behind on this part of the immune system.
A group of researchers led by Annika Karlsson at the Karolinska Institute in Sweden focuses on T cells targeting virus-infected cells and, unsurprisingly, saw that they can play a role in SARS-CoV-2 infection. Other labs have shown that vaccination and natural exposure to the virus generates different patterns of T cell responses.
The Swedes also looked at another member of the coronavirus family, OC43, which circulates widely and is one of several causes of the common cold. The molecular structure of OC43 is similar to its more deadly cousin SARS-CoV-2. Sometimes a T cell response to one virus can produce a cross-reactive response to a similar protein structure in another virus, meaning that T cells will identify and respond to the two viruses in much the same way. Karlsson looked to see if T cells for OC43 from a wide age range of patients were cross-reactive to SARS-CoV-2.
And that is what they found, as reported in the PNAS study last month; there was cross-reactive activity, but it depended on a person’s age. A subset of a certain type of T cells, called mCD4+,, that recognized various protein parts of the cold-causing virus, OC43, expressed on the surface of an infected cell – also recognized those same protein parts from SARS-CoV-2. The T cell response was lower than that generated by natural exposure to SARS-CoV-2, but it was functional and thus could help limit the severity of COVID-19.
“One of the most politicized aspects of our pandemic response was not accepting that children are so much less at risk for severe disease with COVID-19,” because usually young children are among the most vulnerable to pathogens, says Monica Gandhi, professor of medicine at the University of California San Francisco.
“The cross-reactivity peaked at age six when more than half the people tested have a cross-reactive immune response,” says Karlsson, though their sample is too small to say if this finding applies more broadly across the population. The vast majority of children as young as two years had OC43-specific mCD4+ T cell responses. In adulthood, the functionality of both the OC43-specific and the cross-reactive T cells wane significantly, especially with advanced age.
“Considering that the mortality rate in children is the lowest from ages five to nine, and higher in younger children, our results imply that cross-reactive mCD4+ T cells may have a role in the control of SARS-CoV-2 infection in children,” the authors wrote in their paper.
“One of the most politicized aspects of our pandemic response was not accepting that children are so much less at risk for severe disease with COVID-19,” because usually young children are among the most vulnerable to pathogens, says Monica Gandhi, professor of medicine at the University of California San Francisco and author of the book, Endemic: A Post-Pandemic Playbook, to be released by the Mayo Clinic Press this summer. The immune response of kids to SARS-CoV-2 stood our expectations on their head. “We just haven't seen this before, so knowing the mechanism of protection is really important.”
Why the T cell immune response can fade with age is largely unknown. With some viruses such as measles, a single vaccination or infection generates life-long protection. But respiratory tract infections, like SARS-CoV-2, cause a localized infection - specific to certain organs - and that response tends to be shorter lived than systemic infections that affect the entire body. Karlsson suspects the elderly might be exposed to these localized types of viruses less often. Also, frequent continued exposure to a virus that results in reactivation of the memory T cell pool might eventually result in “a kind of immunosenescence or immune exhaustion that is associated with aging,” Karlsson says. https://leaps.org/scientists-just-started-testing-a-new-class-of-drugs-to-slow-and-even-reverse-aging/particle-3 This fading protection is why older people need to be repeatedly vaccinated against SARS-CoV-2.
Policy implications
Following the numbers on COVID-19 infections and severity over the last three years have shown us that healthy young people without risk factors are not likely to develop serious disease. This latest study points to a mechanism that helps explain why. But the inertia of existing policies remains. How should we adjust policy recommendations based on what we know today?
The World Health Organization (WHO) updated their COVID-19 vaccination guidance on March 28. It calls for a focus on vaccinating and boosting those at risk for developing serious disease. The guidance basically shrugged its shoulders when it came to healthy children and young adults receiving vaccinations and boosters against COVID-19. It said the priority should be to administer the “traditional essential vaccines for children,” such as those that protect against measles, rubella, and mumps.
“As an immunologist and a mother, I think that catching a cold or two when you are a kid and otherwise healthy is not that bad for you. Children have a much lower risk of becoming severely ill with SARS-CoV-2,” says Karlsson. She has followed public health guidance in Sweden, which means that her young children have not been vaccinated, but being older, she has received the vaccine and boosters. Gandhi and her children have been vaccinated, but they do not plan on additional boosters.
The WHO got it right in “concentrating on what matters,” which is getting traditional childhood immunizations back on track after their dramatic decline over the last three years, says Gandhi. Nor is there a need for masking in schools, according to a study from the Catalonia region of Spain. It found “no difference in masking and spread in schools,” particularly since tracking data indicate that nearly all young people have been exposed to SARS-CoV-2.
Both researchers lament that public discussion has overemphasized the quickly fading antibody part of the immune response to SARS-CoV-2 compared with the more durable T cell component. They say developing an efficient measure of T cell response for doctors to use in the clinic would help to monitor immunity in people at risk for severe cases of COVID-19 compared with the current method of toting up potential risk factors.
