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."

The Toxic Effects of Noise and What We’re Not Doing About It
Erica Walker had a studio in her Brookline, Mass. apartment where she worked as a bookbinder and furniture maker. That was until a family with two rowdy children moved in above her.
The kids ran amuck, disrupting her sleep and work. Ear plugs weren’t enough to blot out the commotion. Aside from anger and a sense of lost control, the noise increased her heart rate and made her stomach feel like it was dropping, she says.
That’s when Walker realized that noise is a public health problem, not merely an annoyance. She set up her own “mini study” on how the clamor was affecting her. She monitored sound levels in her apartment and sent saliva samples to a lab to measure her stress levels.
Walker ultimately sold her craft equipment and returned to school to study public health. Today she is assistant professor of epidemiology and director of the Community Noise Lab at the Brown University School of Public Health. “We treat noise like a first world problem—like a sacrifice we should have to make for modern conveniences. But it’s a serious environmental stressor,” she asserts.
Our daily soundscape is a cacophony of earsplitting jets, motorcycles, crying babies, construction sites or gunshots if you’re in the military. Noise exposure is the primary cause of preventable hearing loss. Researchers have identified links between excessive noise and a heightened risk of heart disease, metabolic disorders, anxiety, depression, sleep disorders, and impaired cognition. Even wildlife suffers. Blasting oil drills and loud shipping vessels impede the breeding, feeding and migration of whales and dolphins.
At one time, the federal government had our back… and our ears. Congress passed the Noise Control Act in 1972. The Environmental Protection Agency set up the Office of Noise Abatement and Control (ONAC) to launch research, explore solutions and establish noise emission standards. But ONAC was defunded in 1981 amidst a swirl of antiregulatory sentiment.
Impossibly Loud and Unhealthy
Daniel Fink. a physician, WHO consultant, and board chair of The Quiet Coalition, a program of the nonprofit Quiet Communities, likens the effect of noise to the invisible but cumulative harm of second-hand smoke. About 1 in 4 adults in the U.S. who report excellent to good hearing already have some hearing loss. The injury can happen after one loud concert or from years with a blaring TV. Some people are more genetically susceptible to noise-related hearing loss than others.
“People say noise isn’t a big deal but it bothers your body whether you realize it or not,” says Ted Rueter, director of Noise Free America: A Coalition to Promote Quiet. Noise can chip away at your ears or cardiovascular system even while you’re sleeping. Rueter became a “quiet advocate” while a professor at UCLA two decades ago. He was plagued by headaches, fatigue and sleep deprivation caused by the hubbub of Los Angeles, he says.
The louder a sound is, and the longer you are exposed to it, the more likely it will cause nerve damage and harmful fluid buildup in your inner ear. Normal speech is 50-60 decibels (dBs). The EPA recommends that 24-hour exposure to noise should be no higher than 70 weighted decibels over 24 hours (weighted to approximate how the human ear perceives the sound) to prevent hearing loss but a 55 dB limit is recommended to protect against other harms from noise, too.
The decibel scale is logarithmic. That means 80 dB is 10 times louder than 70 dB. Trucks and motorcycles run 90 dBs. A gas-powered leaf blower, jackhammer or snow blower will cost you 100 dBs. A rock concert is in the 110 dB range. Aircraft takeoffs or sirens? 120 dBs.
Walker, the Brown professor, says that sound measurements often use misleading metrics, though, because they don’t include low frequency sound that disturb the body. The high frequency of a screeching bus will register in decibels but the sound that makes your chest reverberate is not accounted for, she explains. ‘How loud?’ is a superficial take when it comes to noise, Walker says.
After realizing the impact of noise on her own health, Erica Walker was inspired to change careers and become director of the Community Noise Lab at the Brown University School of Public Health.

Fink adds that the extent to which noise impairs hearing is underestimated. People assume hearing loss is due to age but it’s not inevitable, he says. He cites studies of older people living in quiet, isolated areas who maintain excellent hearing. Just like you can prevent wrinkles by using sunscreen, you can preserve hearing by using ear plugs when attending fireworks or hockey games.
You can enable push notifications on a Smart Watch to alert you at a bar exceeding healthy sound levels. Free apps like SoundPrint, iHEARu, or NoiseTube can do decibel checks, too, but you don’t need one, says Fink. “If you can’t carry a conversation at normal volume, it’s too loud and your auditory health is at risk,” he says.
About 40 million U.S. adults, ages 20-69, have noise-induced hearing loss. Fink is among them after experiencing tinnitus (ringing or buzzing in the ears) on leaving a raucous New Year’s Eve party in 2007. The condition is permanent and he wears earplugs now for protection.
Fewer are aware of the link between noise pollution and heart disease. Piercing noise is stressful, raising blood pressure and heart rate. If you live near a freeway or constantly barking dog, the chronic sound stress can trigger systemic inflammation and the vascular changes associated with heart attacks and stroke.
Researchers at Rutgers University’s Robert Wood Johnson Medical School, working with data from the state’s Bureau of Transportation, determined that 1 in 20 heart attacks in New Jersey during 2018 were due to noise from highways, trains and air traffic. That’s 800 heart attack hospitalizations in the state that year.
Another study showed that incidence of hypertension and hardening arteries decreased during the Covid-19 air lockdown among Poles in Krakow routinely exposed to aircraft noise. The authors, comparing their pre-pandemic 2015 results to 2020 data, concluded it was no coincidence.
Mental health takes a hit, too. Chronic noise can provoke anxiety, depression and violence. Cognitively, there is ample evidence that noise disturbance lowers student achievement and worker productivity, and hearing loss among older people can speed up cognitive decline.
Noise also contributes to health disparities. People in neighborhoods with low socioeconomic status and a higher percentage of minority residents bear the brunt of noise. Affluent people have the means to live far from airports, factories, and honking traffic.
Out, Out, Damn Noise
Europe is ahead of the U.S. in tackling noise pollution. The World Health Organization developed policy guidelines used by the European Environment Agency to establish noise regulations and standards, and progress reports are issued.
Americans are relying too much on personal protective equipment (PPE) instead of eliminating or controlling noise. The Centers of Disease Control and Prevention rank PPE as the least useful response. Earplugs and muffs are effective, says Walker, but these devices are “a band-aid on a waterfall.”
Editing out noise during product design is the goal. Engineers have an arsenal of techniques and know-how for that. The problem is that these solutions aren’t being applied.
A better way to lower the volume is by maintaining or substituting equipment intended for common use. Piercing building alarms can be replaced with visual signals that flash alerts. Clanking chain and gear drives can be swapped out with belt drives. Acoustical barriers can wall off highway noise. Hospitals can soften beeping monitors and limit loudspeaker blasts. Double paned windows preserve quiet.
Editing out noise during product design is the goal. Engineers have an arsenal of techniques and know-how for that. The problem is that these solutions aren’t being applied, says Jim Thompson, an engineer and editor of the Noise Control Engineering Journal, published by the Institute of Noise Control Engineering of the USA
Engineers have materials to insulate, absorb, reflect, block, seal or diffuse noise. Building walls can be padded. Metal gears and parts can be replaced with plastic. Clattering equipment wheels can be rubberized. In recent years, building certifications such as LEED have put more emphasis on designs that minimize harmful noise.
Walker faults urban planners, too. A city’s narrow streets and taller buildings create a canyon effect which intensifies noise. City planners could use bypasses, rerouting, and other infrastructure strategies to pump down traffic volume. Sound-absorbing asphalt pavement exists, too.
Some municipalities are taking innovative measures on their own. Noise cameras have been installed in Knoxville, Miami and New York City this year and six California cities will join suit next year. If your muffler or audio system registers 86 dB or higher, you may receive a warning, fine or citation, similar to how a red-light camera works. Rueter predicts these cameras will become commonplace.
Based on understanding how metabolic processes affect noise-induced hearing loss in animal models, scientists are exploring whether pharmacological interventions might work to inhibit cellular damage or improve cellular defenses against noise.
Washington, DC, and the University of Southern California have banned gas-powered leaf blowers in lieu of quieter battery-powered models to reduce both noise and air pollution. California will be the first state to ban the sale of gas-powered lawn equipment starting 2024.
New York state legislators enacted the SLEEP (Stop Loud and Excessive Exhaust Pollution) Act in 2021. This measure increases enforcement and fines against motorists and repair shops that illegally modify mufflers and exhaust systems for effect.
“A lot more basic science and application research is needed [to control noise],” says Thompson, noting that funding for this largely dried up after the 1970s. Based on understanding how metabolic processes affect noise-induced hearing loss in animal models, scientists are exploring whether pharmacological interventions might work to inhibit cellular damage or improve cellular defenses against noise.
Studying biochemical or known genetic markers for noise risk could lead to other methods for preventing hearing loss. This would offer an opportunity to identify people with significant risk so those more susceptible to hearing loss could start taking precautions to avoid noise or protect their ears in childhood.
These efforts could become more pressing in the near future, with the anticipated onslaught of drones, rising needs for air conditioners, and urban sprawl boding poorly for the soundscape. This, as deforestation destroys natural carbon absorption reservoirs and removes sound-buffering trees.
“Local and state governments don’t have a plan to deal with [noise] now or in the future,” says Walker. “We need to think about this with intentionality.”
