World Intellectual Prop Org: Rise of China as World's Largest IP Powerhouse

No. 5 Guangdong province, 15.5

Martin Jetpack, the world's first practical and commercial jetpack, which is developed by KuangChi Science, an innovative high-tech startup in Shenzhen, Guangdong province.[Provided to China Daily]

My cousin works for the company here in New Zealand that actually developed and owns the Martin Jetpack. A clue to the origins of this invention are in the name, it was entirely developed by New Zealander Glenn Neal Martin over a period of more than 30 years.

https://en.wikipedia.org/wiki/Martin_Jetpack

It wasn't developed by KuangChi Science, they are an investor with a non controlling 22.7% share. Controlling interest remains with a consortium of New Zealand businessmen including founder Glenn Martin. It is an ASX listed company.

Martin aircraft company issued a statement correcting the press releases from KuangChi, which wrongly stated that production of the Martin jet-pack would be moved to Guangzhou. Only the production of jet packs intended for sale in China will be produced there.

Many falling characteristics of the Japanese economy mentioned in the thread is true, such as the decreasing and aging population and the dropping of Japanese companies in the electronic industry. Naturally, the nuclear industry took a major hit as well. Toshiba has lost major profits and Sharp has been bought by Foxconn.

But there are positives about the Japanese economy as well. As mentioned already, cars remain strong. Shinkansen seems to be doing well too. Sony turned around and is in profits right now. Japanese entertainment of course continues to do very well with video games, music, and anime. There's been a general increase, although slow, in Japanese aerospace. While there have been many delays with the Mitsubishi Regional Jet, it appears that it will eventual make sales as some contracts for it have been secured. Japanese jet engine technology continues to grow, with the latest implementation of Japanese jet engines in the P1 Maritime aircraft. Also Pratt & Whitney will jointly develop a new generation of engines with IHI, Kawasaki, and Mitsubishi.

The the usual case is that it is neither great optimism nor is it great depression. But some where in the middle. But in seems to be slightly positive rather than completely stagnant as it was before.

It should be considered that Japan's economy is performing as it is right now with the great majority of its nuclear power plants still offline. Some are slowly coming back online. As these come back online, then the Japanese economy will be able to operate under less price pressure and the nuclear industry will be able to make a mild recovery, but of course, probably will never return to the level of health prior to 2011.

There are of course many ways to measure GDP. English news articles always present the GDP in US dollars. GDP in US dollars, while a valid point to consider, still gives just one part of the picture. But of course the Japanese economy runs on Yen, not dollars, and in Japanese Yen, the Japanese economy is larger than it has ever been. Naturally there has not been major inflation of Yen. The Yen is not so weak right now, at about 1USD=112 Yen, stronger than what it was in 2015.

Nominal GDP in USD

Nominal GDP in yen (achieved historical high in 2016. This year will be a little more)

PPP GDP in USD

Real GDP in yen (influence from price fluctuations removed)

Common sense is not always accurate. Try comparing say Japan and China qualitatively. Which will be qualitatively better? Clearly Japan does not produce nuclear submarine or fighter jet engines or radars right now. Will you say Japan's economy is qualitatively weaker than china?

Of course Japan is weaker than China economically on a qualitative basis.

Have you been living under a rock?

Who builds the world's fastest supercomputer? China

Who builds the world's fastest high-speed-rail? China, which is 100km/hr faster than the Japanese.

Who is ahead in semiconductors? China (SMIC is moving to 14nm). Japan's last fab was Fujitsu that dropped out after 28nm.

Who has the world's largest telecom company? China. Huawei is crushing Ericsson. Japan is a no-show in telecom carrier manufacturing.

Who is huge in online sales? China. Alibaba is a monster. Japan has nothing comparable.

China is also starting to dominate the new industries. DJI is valued at about $10 billion in the consumer drone business. Japan is a no-show in consumer drones.

China is strong in many high-tech industries and earns a huge trade surplus of about $560 billion per year from its high-margin items.

China is expanding into sales of military drones, submarines, and civilian aircraft. China keeps powering ahead and Japan is a no-show in critical industries. Hence, Japan barely breaks even in trade.

Supercomputers are about many factors, not just speed. They need to be designed to be easy to program for various complex and specific tasks, other wise it'll take a long time to prepare code for a single task. The longer it takes to carrying out a tasks, the less tasks that can be done. If all tasks were just basic arithmetic, then speed is a dominant feature. But calculating the effects of earthquakes, supernova, weather, and so on are not simple calculations. Thus the ability to program the supercomputer is also vital.

Chinese highest speed trains are based off of the Siemens Velaro trains and much of the technology is imported by China and they just assemble the trains. Not genuine Chinese tech. If the components imports stopped, then China can no longer make the trains.

Japan did drop down in semiconductors. One valid point out of 3 so far.

Largest telecom company and huge online sales is by virture of a large population. This is not a demonstration of advance tech. But in Telecomm, Japan does have two very large companies, NTT and SoftBank.

Drones looks like another fair point. 2 out of 6.

As for military equipment, Japan has only relaxed laws that enable to sale military equipment about just 1 year ago. China has been in the defense market for decades. I almost feel stupid in having to point out the advance weapons that Japan has produced.. Type 10 tank, Type 16 maneuver combat vehicle, joint-development with the US with SM3 BlockIIA 1500km range missile defense, Soryu sub, P1 maritime aircraft, C-2 cargo aircraft, and so on.

Everyone knows that Japan has high tech. I think you are trolling.

I am absolutely right on every point.

China builds its own chips and interconnect software. Japan buys American chips. China's supercomputer is 100% indigenous. Japan's supercomputer was based on American hardware technology.

The "China Star" was a completely indigenous Chinese high-speed-train with a top speed of 270km/hr (168 mph) that debuted in 2002. It is unclear the degree that German technology influenced China's current high-speed trains. However, China clearly possessed the full gamut of technologies for a high-speed train without any foreign assistance.
China owns about 1,000 patents for its upgraded 350km/hr high-speed-trains. Japan's bullet train is based on old technology and is slower by 100km/hr.

Huawei built the world's first gigabit switches and was a pioneer in software-defined-networks (SDN). Japan does not build hardware for telecommunication carriers. Ericsson and Nokia compete against Huawei, but there's no Japanese competitor. Japan's NTT and SoftBank are mere buyers of telecom technology from Huawei, Ericsson, and/or Nokia. A consumer of technology (Japan's NTT and SoftBank) is not the same as a supplier of technology (China's Huawei).

Japanese military technology is based on licensed American technology. Japan does not build turbofan jet engines. All of the assembly equipment and single-bladed nickel-superalloy crystals for the turbofan engine fan-blades are purchased from the US. In contrast, China developed its own nickel-titanium superalloys (DD3 and DD6) that are used in China's indigenous WS-10A turbofan jet engines.

In conclusion, China is clearly far superior to Japan in almost every aspect of high technology. One last example, China's Long-March rockets are indigenous and have the world's best safety record over decades. However, Japan's H-1 rockets are based on American Delta rockets. Japan is a mere licensee of American technology. Japan's indigenous H-2 rocket program was a failure and it was canceled.
----------

Japanese Rockets | Historic Spacecraft

"The H-1 rocket first stage was a license-built version of an American Delta rocket first stage. The upper stages were of Japanese design."

----------

I will mention a few more examples, because China is clearly superior to Japan in technology.

1. China builds fifth-generation J-20 heavyweight and J-31 medium-weight stealth fighters. Japan begs the US to buy 42 F-35s.

2. China builds Type 093 nuclear attack submarines. This is high-technology, because a compact nuclear reactor is very difficult. Japan doesn't build nuclear submarines, because it doesn't have the technology.

3. China builds GBI (ie. ground-based interceptors) that have successfully shot MRBMs or ICBMs out of the sky. Japan is waiting to buy American technology.

4. China put a man into space about a decade ago. Japan has no such capability.

5. China built a hypersonic glide vehicle (HGV). Japan has no such capability.

6. China built its own Beidou GPS system. Japan begs the US for access to the American GPS network.

7. China's Type 052C/D "Chinese Aegis" destroyers are indigenous and operate on Chinese software. In contrast, Japan pays the US to install "downgraded" Aegis software and capability on Japanese Kongo-class ships (for reference, read GlobalSecurity article). One example of the inferiority of downgraded Japanese destroyers is the lack of Tomahawk cruise missiles, which the US refuses to sell to Japan due to the offensive nature of Tomahawk cruise missiles.

The list goes on. This is not a close comparison.

Chipset makers do not control the computer market. Software is more important, along with its programming. It is a globalized world, Japan buys foreign chipsets, and programs better functional supercomputer. Software holds more influence in the computer industry ever since Microsoft made some sort of deal with IBM in the late 1980s. So being a chipset maker is not as big of a point as you think. This point applies to the telecomm companies. The original point was size of the company, the presence it has in the market, NTT is a huge company with massive earnings.

China made the "China Star" but trains afterwards were foreign based.
CRH2 <=== Kawasaki
CRH3 <=== Siemens
CRH380B <=== Siemens
CRH380CL <=== Hitachi
CRH380D <=== Bombardier

On the military, Type 10 tank use Japanese technology, not AMerican. The gun is a new Japanese L44 120mm cannon, not the Rheinmetall based 120mm gun. The 120mm APFSDS is also new Japanese design, not a German based munition. The suspension is Japanese. It is the first tank in the world to use continuously variable transmission. 105mm cannon and its ammo is also Japanese made, not foreign based. The jet engines in the P1 maritime aircraft are IHI F7 Turbo fan engines at about 6.1 tons of thrust. The jet engines in the X-2 stealth demonstrator are also Japanese, at 5 tons of thrust. They are currently doing studies into a 15 ton class fighter jet engine. Many missiles, be it land based, air based, or ship based, are domestically developed. And an air-to-ship anti-ship missile is also being developed that will have speeds of mach 3 called the XASM-3.


About the space rockets, H2 is no longer used. Japan has been using the H2A rocket (32 out of 33 success) rocket and the H2B rocket (6 out of 6 success). They are developing a new rocket, the H3, which will cut launch cost by as much as 50%.

About the list of things that China achieves where Japan relays on the US.. that is part of being an ally and sharing the same international order. Japan does not oppose it so it does not need to recreate all the tactical and strategic elements for itself. So it just cooperates with the US. But let's take a look at some of the things you listed anyway..

F-35 will be used by many partner countries. So it will increase interoperability. The Australians, the British, the Americans, by using the same aircraft, it blends their capabilities together and thus joint-operations is easier. Same logistic chain for everyone. Why develop a new separate supply chain?

Japan has a sort of allergy towards nuclear power, so they restrict the use, for better or for worse. Soryu subs are still quite capable and the last models of the Soryu-class will use a full LIB set. Nuclear sure has its advantages, oh well. Japan and the US are jointly working together on the new SM3-IIA missile. It is a partnership. All these partnerships ultimately mean that when China calculates what it takes to beat the US, they have to pile Japan on top of the US in their estimates.

Link has all sort of Japanese missiles and radars.
http://www.mod.go.jp/j/approach/agenda/meeting/seisan/sonota/pdf/05/001.pdf

Speaking of radars, Japan has 28 Japanese-made radar stations such as FPS-5.

Japan has the "Kibou" module attached to the International Space Station that all partners can benefit. It is the only module that has an airlock and robotic arm that enables astronauts to remain inside the station while putting experiments out side on a platform. Chinese space station has no such feature for putting experiments outside. They would have to do a time consuming spacewalk just to set outside even a tiny 1kg experiment outside the station. Japanese astronauts are able to go on long duration missions at the space station, currently during 6 month long missions. Chinese are trying to do everything by themselves. Technically speaking, Japanese astronauts have far more in-space experience than Chinese.

HGV? Japan can leave it to the Americans to compete in that regard.

GPS, another dependency on the US I guess. Japan is launching their on satellites that will improve the performance of GPS for them. SDF is also launching their own communication and spy satellites as well.

Completely ignored my post. What a troll.

You didn't say anything that disagreed with my list.

Has Japan built a stealth fighter? Nope. Japan does not possess advanced stealth technology to evade radar.

Has Japan built a nuclear submarine with a compact nuclear reactor? Nope. Japan does not possess incredible engineering technology.

Has Japan built its own nickel-titanium superalloy single-crystal turbofan-engine fan blade? Nope. Japan does not possess that incredible level of material science.

Has Japan put a person into space? Nope. Japan does not possess incredibly-reliable life-support technology to operate in the cold vacuum of space.

You get the drift. My analysis is right on target. It's China 12 and Japan 0.

That is cherry picking (assuming those are accurate).

There some fields that China still need to close gap with Japan, such as: robotic, automation, steel making, auto industry, shipbuilding, engines, etc.

 

[Martian2]

There some fields that China still need to close gap with Japan, such as: robotic, automation, steel making, auto industry, shipbuilding, engines, etc.

No. That's not cherry-picking. It's widely acknowledged high-technology.

China's stealth fighters and manned space flights receive worldwide media coverage. Everyone around the world knows its high-technology and only two countries are capable of building true fifth-generation fighters. Only three countries have ever achieved manned space flight.

Steel making is old technology. Autos are no big deal. Many countries make autos. China builds robots, ships, etc.

The question is what incredible feats of technology that one country can build that others can't.

The 12 benchmarks on my list are fair. Japan is not capable of most of them (with the exception of slower high speed trains).

China's high-technology isn't just bragging rights. It translates into power. Chinese stealth fighters will rule Asian skies soon (due to the start of mass manufacturing of J-20 stealth fighters). Japan will cede the skies to China.
----------

Shipbuilding, robotics, etc. are benchmarks as to whether Japan is an industrialized country. There is no question that Japan is industrialized. However, in this thread, we are not discussing whether Japan is industrialized.

We are asking the question as to whether China possesses more advanced technology than Japan.

Unquestionably, the answer is yes. China is far more advanced technologically than Japan. China can build nuclear submarines. Japan has never built a nuclear submarine. Nuclear submarines have virtually unlimited range (with the only limitation of on-board food supply). Countries would build nuclear submarines if they had the technology. Since Japan can't build a nuclear submarine, Japan places lower than China on the advanced technology ladder.

Similarly, after evaluating the 12 benchmarks (where very few countries are capable of producing the advanced technology), China comes out ahead of Japan in all 12 benchmarks. It's a slam dunk.

 

[Shotgunner51]

Has Japan built its own nickel-titanium superalloy single-crystal turbofan-engine fan blade?

Yes they do. While CMSX-10 now used in F119/135 (for F-22, F-35 etc) is 3rd generation SC (Single Crystal) superalloy is considered apex of SC tech, NIMS Japan has already advanced to 5th gen SC superalloy TMS-162, as well as TMS-192/196 in due course.

http://www.tandfonline.com/doi/pdf/10.1179/174892407X205254
http://www.tms.org/superalloys/10.7449/2008/Superalloys_2008_131_138.pdf​

In fact Japan leads the world in steel/metallurgy and materials. Toray, Toho Tenax and Mistsubishi Rayon dictate synthetic/carbon fibers. Since 1990's Nichia Corporation already leads GaAs tech which is core for AESA, say APG77 of F22 as well as APG81 of F35, and Nicha has further advanced to GaN tech. On steel best known are Nippon Steel, JFE and many world-class special steel (SS) firms, JSW alone accounts for 80% of world's reactor pressure shells and heavy forged components.

There are numerous other examples (see Global Top 100 Patent Filers, 46 corporations are from Japan), generally speaking Japan leads the world in advanced materials, optics, precision manufacturing, robotics/automation, precision tool and CNC machinery.

However since Japan has limited public expenditure (constitutional budget limit to 1% of GDP) for defence-related tech, can't export assembled defence systems (constitutional export ban), Japanese tech firms primarily focus on civilian businesses (commercial), or export to foreign defence contractors in form of processed materials, components, machinery, or tools.

That's my top 12 list. It's China 12 and Japan 0 in high-technology.

Similarly, after evaluating the 12 benchmarks (where very few countries are capable of producing the advanced technology), China comes out ahead of Japan in all 12 benchmarks.

Yes, China is constraint-free on defence budget (well, there is self-discipline) nor export ban (again, self-imposed is another story e.g. supercomputers, MALE UAV), few nations can afford to build SSBN or can export ballistic missiles, so I believe China does have advantages on defence-driven techs. Also, absolute size of public budgets are bigger, so China has advantages on natural-science-related techs (non-commercial), for example supercomputing, space exploration and such.
