On September 8, 2026, the World Intellectual Property Organization (WIPO) announced the world’s top 100 innovation clusters in the 2026 Global Innovation Index (GII).
Shenzhen–Hong Kong–Guangzhou ranked first for the second consecutive year. Tokyo–Yokohama came in second, followed by San Jose–San Francisco in third, Seoul in fourth, and Beijing in fifth. Shanghai–Suzhou also placed sixth, meaning that three Chinese clusters ranked among the global top 10.
By country, China had the largest number of clusters in the top 100, with 25, surpassing the United States with 20. Germany followed with seven, while India and the United Kingdom each had four. China and the United States alone now account for nearly half of the world’s top 100 innovation clusters.
At first glance, this might look like another sign that China has overtaken Japan in innovation capacity.
A closer look at the rankings, however, reveals a much more complicated picture.
What deserves greater attention is the fact that global innovation competition is gradually shifting away from a contest over “who files the most patents” toward a contest over “who can create the strongest regional cycle connecting research, patents, and capital.”
This Is Not a “Patent Ranking”
The first point to understand is what WIPO’s innovation cluster ranking actually measures.
The current ranking is based primarily on three types of data: the locations of inventors named in PCT international patent applications, the affiliations of authors of scientific publications, and the locations of companies that have raised venture capital.
In other words, it does not measure corporate R&D alone. It evaluates regional innovation activity more broadly, incorporating academic research conducted by universities and research institutions as well as investment in startups.
This distinction is extremely important.
Outstanding research does not automatically translate into economic innovation if it is never commercialized. Conversely, even a vibrant startup investment environment cannot be sustained if the underlying technologies are not being created.
The ranking therefore seeks to identify places where researchers, inventors, companies capable of commercialization, and investors providing capital are geographically concentrated and able to interact with one another.
For that reason, it is more accurate to view this ranking not simply as a measure of technological strength, but as a ranking of the concentration and strength of innovation ecosystems.
Why Shenzhen–Hong Kong–Guangzhou Surpassed Tokyo–Yokohama
One particularly interesting point is that Tokyo–Yokohama remains exceptionally strong in patents.
According to WIPO’s 2026 PCT Yearly Review, among PCT applications published between 2021 and 2025, Tokyo–Yokohama accounted for 132,669 applications, or 10.1% of the global total, making it the world’s largest geographic cluster by this measure. Shenzhen–Hong Kong–Guangzhou followed with a 9.2% share.
In other words, it would be inaccurate to interpret Tokyo–Yokohama’s second-place finish as evidence that Shenzhen has overtaken it in patent competitiveness.
The change in ranking is partly the result of a change in methodology.
Until 2024, Tokyo–Yokohama ranked first globally, while Shenzhen–Hong Kong–Guangzhou ranked second. Beginning in 2025, however, venture capital transactions were incorporated more substantially into the assessment. Because Shenzhen–Hong Kong–Guangzhou outperformed Tokyo–Yokohama in VC activity, it moved into first place overall. WIPO itself explained that the introduction of the VC indicator affected the change in ranking in 2025.
That order was maintained in 2026.
Rather than showing a decline in Japan’s technological capabilities, this seems to symbolize a broader change in what counts as innovation: the scope of evaluation has expanded from “invention” to “invention + research + commercialization capital.”
China’s Real Strength Lies Not in “No. 1,” but in “25 Hubs”
The number that stands out most to me in this year’s ranking is not “No. 1,” but “25.”
China now has 25 clusters in the global top 100, more than any other country and ahead of the United States with 20.
If Shenzhen–Hong Kong–Guangzhou were the only extraordinarily strong Chinese cluster, it might be possible to describe China’s innovation system as highly concentrated in one region. But that is not the case.
Beijing ranks fifth, Shanghai–Suzhou sixth, and many other Chinese cities also appear in the global top 100.
Moreover, these regions are not all strong in the same way.
According to WIPO’s analysis, Beijing and Shanghai–Suzhou are particularly strong in scientific publications, while Shenzhen–Hong Kong–Guangzhou ranks highly not only in PCT applications but also in venture capital activity. In the United States, meanwhile, clusters such as San Jose–San Francisco and New York have an overwhelming presence in VC activity.
In other words, the world’s leading innovation clusters are not becoming strong through a single common model.
Some are built around universities and research institutions. Others are centered on major technology companies, manufacturing industries, or startup and venture capital ecosystems.
What distinguishes China is that it is beginning to develop several of these different types of clusters within the same country.
Ningde’s Rapid Rise Reveals Another Chinese Model
Another symbolic example is Ningde in Fujian Province.
Ningde climbed 24 places, from 99th in 2025 to 75th in 2026, the largest rise among all clusters in the top 100. According to WIPO, its PCT applications increased by 38.7%, scientific publications by 24.7%, and venture capital activity by 50.0%. In terms of innovation “intensity” adjusted for population size, Ningde ranks third in the world.
Ningde is best known as the home of CATL, one of the world’s largest manufacturers of batteries for electric vehicles. According to WIPO data for 2025, CATL alone accounted for 82% of PCT applications originating from the region.
This represents a model of innovation cluster formation that is entirely different from Silicon Valley.
One model creates a vast ecosystem through the concentration of numerous startups. Another builds a cluster around a globally competitive anchor company, drawing R&D, talent, suppliers, and investment into the surrounding region.
Looking at the industries in which China has strengthened its competitiveness—electric vehicles, batteries, solar power, telecommunications equipment, and others—the latter model may become increasingly important in the years ahead.
What Tokyo–Yokohama’s No. 2 Ranking Reveals About Japan’s Strengths and Weaknesses
How, then, should Japan interpret these results?
There is little reason for pessimism.
Tokyo–Yokohama ranks second in the world and remains the largest geographic cluster globally in terms of PCT applications. In the 2026 ranking, Mitsubishi Electric is listed as a leading PCT applicant in the Tokyo–Yokohama cluster, while the University of Tokyo is identified as a leading institution for scientific publications. The top three clusters—Shenzhen–Hong Kong–Guangzhou, Tokyo–Yokohama, and San Jose–San Francisco—together account for more than one-fifth of all PCT applications worldwide.
It is reasonable to conclude that the technological depth generated by Japanese companies and universities remains among the strongest in the world.
At the same time, however, the rankings also highlight Japan’s challenges.
Tokyo–Yokohama is the global leader in patents, yet ranks second overall once venture capital and other indicators are included. By contrast, San Jose–San Francisco does not surpass Tokyo–Yokohama in PCT applications alone, but its overwhelming VC activity helps place it third overall.
This illustrates an important distinction: the ability to create technology and the ability to transform technology into new companies and industries are not the same thing.
Japan’s challenge, therefore, may not simply be to increase the number of patent applications.
What matters increasingly is whether Japan can create a self-reinforcing cycle in which university research produces startups, capital flows in from corporations and venture capital firms, successful companies attract further talent and R&D investment, and that in turn generates the next wave of inventions.
Global Innovation Competition Is Shifting from “Company vs. Company” to “Region vs. Region”
The WIPO ranking also reveals another major shift.
The unit of technological competition is increasingly becoming not only the company or the nation, but the metropolitan region.
Shenzhen–Hong Kong–Guangzhou is home to Huawei and many other companies. Tokyo–Yokohama contains a dense concentration of Japanese companies and universities. San Jose–San Francisco brings together technology companies such as Google, Stanford University, and one of the world’s largest venture capital markets.
WIPO similarly identifies Huawei, Mitsubishi Electric, and Google as leading PCT applicants in these respective clusters, and Sun Yat-sen University, the University of Tokyo, and Stanford University as leading institutions for scientific publications.
Comparing companies alone therefore makes it increasingly difficult to understand the full structure of technological competition.
Entire regions—including companies, universities, researchers, startups, investors, and labor markets—are competing as enormous integrated “innovation machines.”
Japan Should Also Pay Attention to the “25 vs. 3” Gap
From that perspective, what should concern Japan more than the difference between first and second place is the breadth of its innovation cluster base.
China has 25 clusters in the global top 100, giving it the broadest innovation cluster network in the world. Moreover, regional cities such as Ningde are rapidly climbing the rankings by building around specific industries.
Having a world-class mega-cluster such as Tokyo–Yokohama is an enormous asset for Japan.
But future competition may depend not only on the strength of a single dominant cluster, but also on whether multiple regions centered on different industries and technologies can each create their own cycles of research, patents, entrepreneurship, and investment.
Rather than concentrating everything in Tokyo, Japan will increasingly need to consider how to connect regional industrial strengths—in automobiles, semiconductors, robotics, advanced materials, biotechnology, batteries, and other sectors—with local universities, startups, and investment capital.
More Important Than the Ranking Is What Comes After the Invention
Looking only at the headline result—Shenzhen–Hong Kong–Guangzhou first and Tokyo–Yokohama second—it may be tempting to conclude that Chinese technological strength has overtaken Japan’s.
But a closer examination of WIPO’s data reveals a far more nuanced picture.
Tokyo–Yokohama remains one of the world’s largest centers for PCT applications. Shenzhen–Hong Kong–Guangzhou, meanwhile, ranks first as a more comprehensive innovation ecosystem that combines patents, scientific research, and venture capital. Across China as a whole, 25 clusters now rank in the global top 100, rapidly broadening the country’s innovation base.
The question this ranking poses to Japan is therefore not simply, “Should we file more patents?”
The deeper question is whether Japan can create regional cycles in which excellent research leads to inventions, those inventions are protected as intellectual property, capital is attracted, businesses grow, and the resulting profits are reinvested into further research and development.
In the next phase of global innovation competition, competitiveness will depend not only on the “number” of patents, but also on the “cycle” connecting the research and investment that come before and after them.
Seen from that perspective, the most important number in WIPO’s 2026 ranking may not be “China No. 1, Japan No. 2.”
It may be China’s “25 clusters.”
