How does the $US12.8 trillion mobile transaction value square with China's GDP of presumably $US12.0 trillion (last year)? :confused:

In its simplest form, GDP measures the value of all the goods and services purchased/consumed by the final users within the economy.

Think of a very basic product like a hammer. That hammer is made of a steel head and a wooden handle. GDP only count the value of this hammer when some buys it.

What isn’t counted in GDP, but which might be countered in the sum total of mobile transactions, could be things like what the maker of the hammer:

- paid his suppliers for the wood, steel and packaging for the finished product
- the labour cost of his employees turning those raw materials into the finished product
- the advertising costs of finding customers for his hammer
- the transportation costs of getting that hammer to the customer

Now supposed his employees and suppliers takes the money they earned from this trade and buy raw materials and/or services themselves. So on and so forth.

Every time someone makes a mobile transaction, it gets counted and added to the sum total of transactions. So you can see how many times the same money could get multiplied within the total transactions count from something as simple as a hammer. The whole point of GDP is to strip out all the double counting.

In essence, GDP growth is a count of value added. If everyone in the economy are all pricing their products at cost and add zero profit margin, all that happens is the same amount of money goes round and round, but the economy will only have the same sum total amount of money no matter how many times money chances hands.

It’s only when you have value added that the economy grows, and that increase is what is expressed by GDP growth.

On the whole, you gave a good explanation of how GDP is generated.

Just want to comment that, other than the labour cost, wood, steel (and other raw materials), packaging and advertising are included in the GDP accounting as under some category of products and services. In regard to labour cost, I believe employee monetary matter are normally handled through bank accounts.

China speeds up research, commercialization of space shuttles

China will accelerate research and commercial use of rocket upper stages, a carrier rocket official said on Friday.

"The Yuanzheng rocket upper stage family will have a new member, Yuanzheng-1S, this year, serving launches for low and medium Earth orbit satellites," said Wang Mingzhe, an upper stage architect of the China Academy of Launch Vehicle Technology (CALT).

Upper stages are independent aircraft installed on the carrier rocket that are capable of restarting their engines multiple times in space to allow them to send different payloads to varying orbits.

Earlier this month, China's Yuanzheng-1 rocket upper stage helped send two satellites into orbit on a single carrier rocket for its domestic BeiDou Navigation Satellite System in Xichang in southwest China's Sichuan Province.

China began to develop upper stage spacecraft in the 1980s, according to a report released by CALT. The first mission took place in March 2015 involving the Yuanzheng-1, which can perform two ignitions and operate for 6.5 hours.

Over the past three years, the Yuanzheng upper stage family has gained two members, Yuanzheng-1A and Yuanzheng-2, which are capable of up to 20 engine restarts and multiple spacecraft separation events.

"In addition to putting satellites into position, the Yuanzheng upper stage family is also able to monitor the space environment and send data back to Earth, which can help gain experience for future aircraft design," said Ye Chengmin, the vice chief architect for upper stages with CALT.

An upper stage is designed to operate at high altitude. Currently, China's three Yuanzheng upper stages all feature medium- and high-orbit missions.

Wang Mingzhe said there is growing demand for putting upper stages into commercial use, such as using them as launch vehicles to send small payloads into low and medium orbits. The new model Yuanzheng-1S will be a simplified version to cater to these needs.

"Compared with the long flight time of three other models, Yuanzheng-1S needs to finish its mission within one hour. This takes a lot of upgrading, such as streamlining systems to make this version more economical and efficient," said Wang.

Yuanzheng-1S is scheduled to be used for launches to Sun-synchronous orbits atop a Long March 2C carrier rocket in 2018.

Wang said that upper stages are expected to play a huge role in future moon and Mars exploration as well as orbital transfer and the clearing of space debris.

In the race to win the 5G market, China’s Huawei took another step forward today when it announced what it claims is the first commercially available 5G chipset.

Called the Balong 5G01, the company says it is compliant with the recent standards that were locked down last December by industry group 3GPP. While 5G is expected to eventually able network speed of 20 Gbps, this first chipset from Huawei offers up to 2.3 Gbps.

There was no pricing information. But Richard Yu, CEO of Huawei’s Consumer Business Group, said the chip was just the latest example of how Huawei is aggressively pushing forward with 5G.

He also demonstrated the

Yu was speaking a day before the official opening of Mobile World Congress in Barcelona, the telecom industry’s largest annual gathering where 5G is expected to be the main theme.

Alibaba Cloud on Friday launched the world’s second-most powerful quantum computing service on the cloud after IBM in association with the Chinese Academy of Sciences.

While Alibaba Cloud’s quantum computer is capable of processing 11 quantum bits (qubits), IBM launched a 20-qubit computer last November.

Shi Yaoyun, chief quantum technology scientist at Alibaba Cloud, said that the launch of the quantum computing service will make it easier for the team to experiment with processors and better understand the hardware required, as well as develop quantum tools and software.

As the kinds of processes and calculations get more complex to compute, quantum computers are often seen as a solution that can help process such calculations much quicker than classical computers.

For example, cracking a complex password via brute force could take a classical computer years, but with a quantum computer, it could just take a few seconds.

While bits in classical computers are binary and can only process the values of 0 or 1 at any one time, qubits are able to hold both values at the same time – otherwise known as a superposition state. This means that at any one time a single qubit can participate in millions of processes. The larger the number of qubits a quantum computer has, the more powerful the computer is.

The launch of the quantum computing service comes after Alibaba Group Holding pledged to invest US$15 billion into next-generation technology last October, including artificial intelligence and quantum computing, as it aims to keep up with global players like Amazon and Google in so-called “moonshot” technologies that could potentially change the technology landscape.

Its ‘Damo’ academy is looking to hire 100 researchers to work on fields like AI, quantum computing and fintech, with plans to launch eight research bases in countries including the US, Israel and Singapore.

Alibaba owns the South China Morning Post.

Via Martian from Pakdef. Slowly they are chipping away at western chip technology monopoly.

China has reached a milestone. Xi'an UnilC Semi is selling its own designs of DDR4 DRAM chips and modules.

"DDR4 SDRAM is the abbreviation for 'double data rate fourth generation synchronous dynamic random-access memory,' the latest variant of memory in computing. DDR4 is able to achieve higher speed and efficiency thanks to increased transfer rates and decreased voltage."

In simple English: DDR4 is the fastest computer memory available.

"DDR4 memory technology is up to twice as fast and delivers 50% more bandwidth and 40% more energy efficiency than DDR3 technology when it was introduced."

"Xi’an UniIC Semiconductors, a memory producer based in China, has started to sell DDR4 DRAM chips and modules that were developed and made in-house. This is the first time when a China-based company develops its own DDR4 memory chips.
...
Xi’an UniIC’s DDR4 lineup includes 4 GB and 8 GB SO-DIMMs, 4 GB and 8 GB UDIMMs as well as a 4 GB UDIMM with ECC, all rated for data transfer rate of 2133 MT/s with CL15 15-15 timings at 1.2 V (according to Xi’an UniIC’s DDR4 product decoder). All the DIMMs are based on Xi’an UniIC’s own DDR4 memory chips featuring 4 Gb capacity. The modules and the chips are not meant to offer breakthrough performance levels and are probably aimed at various inexpensive PCs, most of which will be sold in China."
