China's science and technology sector has seen profound changes over the past decade, characterized by more original breakthroughs in core technologies, higher academic output in both quantity and quality, and assuming a larger role in supporting the national economy, officials said.

The country's ranking in the Global Innovation Index rose from 34th in 2012 to 11th in 2022, according to the World Intellectual Property Organization.

Meanwhile, the National Bureau of Statistics said the nation's gross domestic research and development spending grew from 1.03 trillion yuan ($147.1 billion) in 2012 to more than 2.79 trillion yuan last year, when the R&D budget for basic research reached a record 181.7 billion yuan, 3.4 times higher than that in 2012.

According to the Ministry of Science and Technology, China also boasts the world's largest research workforce, with around 5.62 million full-time personnel last year, a rise of 1.7 times compared with 2012.

Speaking at a news briefing in June, Wang Zhigang, the minister of science and technology, said these scientific indicators show that China has become an innovative country. However, Wang noted that China still has many shortcomings in making original breakthroughs, training high-quality talent and obtaining key and core technologies.

As a result, the country will need to improve basic research, strengthen the role of private companies as pillars of innovation and create new engines for high-quality development through scientific and technological breakthroughs, he added.

As of this year, there are 173 national high-tech industrial development zones in China, 84 more than in 2012, according to the Ministry of Science and Technology.

Li Youping, deputy director of the ministry's Torch High Technology Industry Development Center, said that these zones are the vanguard of China's innovation-driven development strategy as they hold much of the nation's research resources and have contributed greatly to the national economy.

National high-tech zones are home to 84 percent of State Key Laboratories and 78 percent of national technological innovation centers, in addition to more than 4,400 research institutions.

The gross industrial output of these high-tech development zones grew from 5.4 trillion yuan in 2012 to 15.3 trillion yuan last year, and they contributed to 13.4 percent of China's GDP, while only using 2.5 percent of the land available for construction.

The number of high-tech companies in national high-tech zones also rose from less than 20,000 in 2012 to 115,000 last year, Li said.

With these resources, high-tech zones have made numerous breakthroughs in quantum technologies, high-speed rail, the Beidou Navigation Satellite System, the C919 passenger jet, 5G telecommunications and other fields of strategic significance, he added.

Meanwhile, China's first artificial intelligence chip, first quantum communication satellite, first vaccines for COVID-19 and many other breakthroughs were achieved by scientists and companies working in high-tech zones.

With regard to academic output, China overtook the United States as the world leader in both the quantity and quality of scientific papers published from 2018 to 2020, according to an annual report published last month by the National Institute of Science and Technology Policy in Japan.

Chinese research accounted for 27.2 percent, or 4,744 papers, of the world's top 1 percent of highly cited papers from 2018 to 2020. The US accounted for 24.9 percent, or 4,330 papers. It was the first time that China had surpassed the US in this prestigious category, the report noted.

These highly cited papers are studies that outperformed 99 percent of their peers based on the number of citations received. The number of citations is a commonly used measurement of a study's quality and influence.

TIMELINE

2012: The manned submersible Jiaolong sets a national diving record of 7,062 meters in the Marianas Trench on June 27. The feat cements China's position as one of the world's leaders in deep-sea exploration.

2013: The Chang'e-3 lunar probe successfully performs a soft landing on the moon on Dec 14 and deployed China's first lunar rover, Yutu. It is the first time that a Chinese rover has landed on an extraterrestrial object.

2014: Agronomist Yuan Longping and his team set an international record of yielding over 15 metric tons of rice per hectare on Sept 24. It is the first time Yuan's hybrid rice has reached this milestone.

2015: China launches the first completed prototype of the homemade C919 passenger jet on Nov 2. The aircraft makes its maiden flight in 2017.

2016: The five-hundred-meter Aperture Spherical Telescope, the world's largest single-dish radio telescope is completed on Sept 25. It becomes fully operational in 2020.

2017: On Aug 30, China launches the Beijing-Shanghai Backbone Network, the world's first long-distance quantum communication highway. With a length of more than 2,000 kilometers, it connects the cities of Beijing and Shanghai.

2018: In January, the journal Cell announces that Chinese scientists have created the world's first macaques using somatic cell nuclear transfer, the same technique that yielded the famous clone Dolly the Sheep.

2019: On Jan 3, the Chang'e-4 lunar probe, carrying the Yutu 2 rover, makes the first-ever soft landing on the far side of the moon.

2020: On June 23, China launches the last satellite for the Beidou Navigation Satellite System, marking the completion of the deployment of the nation's global navigation system.

2021: On Sept 24, the journal Science reports that Chinese scientists have synthesized starch from carbon dioxide for the first time, a breakthrough that may revolutionize agriculture if the technology becomes economically viable.
