An interesting question - and difficult to answer. We probably have to think about definition first, and then about ways to measure.
Suppose there exists a copy of our world, but without digital economy. Some products can be sold in shops and some online. I do not think that we buy a lot of food online. But yes, we have to buy air tickets today mostly online. Do we travel more because of that? I doubt. It is always more convenient? Not, because stupid computer can block your card while your can always set a deal in travel agency with a person. So we can compare the total values in both worlds as some "sums of individual utilities". The difference between those aggregate values can show the value added to our world by digitization.
There is also some products that exist only virtually, including online games, etc. Some value added is created in networks. But how to count this all and to convert in USD? And some value may exist even in a cloud, with unknown country location.
The term 'Digital Economy' was coined in Don Tapscott's 1995 best-seller The Digital Economy: Promise and Peril in the Age of Networked Intelligence, one of first books to show how the Internet would change the way we did business.
“Origin of Life” in the Internet, we are perhaps just at the beginnings of an evolutionary curve whose ultimate trajectory remains unknown. Today, half the world's population is online, a third are on a social network, 53% are mobile, and they span all ages, races, geographies and attitudes across the planet.
Digital economy refers to an economy that is based on digital computing technologies. The digital economy is also sometimes called the Internet Economy, the New Economy, or Web Economy. Increasingly, the "digital economy" is intertwined with the traditional economy making a clear delineation harder."
The term 'Digital Economy' was first mentioned in Japan by a Japanese professor and research economist in the midst of Japan's recession of the 1990s. In the west the term followed and was coined in Don Tapscott's 1995 book The Digital Economy : Promise and Peril in the Age of Networked Intelligence. The Digital Economy was among the first books to consider how the Internet would change the way we did business.
Very difficult to answer. Still no country wide list available. It is often said world is global village. So you may get answer in future. Good topic for international research.
I think so many priceless results can be considerd for this issue. The main advantages of digital economy is help to environment protection! If money eliminates from commen trads, the cost of produce and maintenance of money and related form of it decline obviously
The digital economy is good for large countries, while for small ones it is disastrous. If digitization was realized with a human approach, then that's ok, however, digitization guided by the motives of profit and control is not good.
I am very skeptical about the digital economy, despite the fact that this area is now heavily advertised. There is a well-known saying "If the stars are lit, it means that someone needs it". I am not an economist and I reason as an amateur, but after reading the text from https://oko-planet.su/finances/financescrisis/396235-cifrovaya-ekonomika-preimuschestva-i-riski-v-sistemnom-podhode-mnenie.html (in Russian) I saw a huge danger and even a tragedy of the digital economy for the world. If now mankind is in an active stage of mental degradation in all spheres of life, then what to expect after the digital economy that will be actively used. In my understanding, this will be a disaster for people. However, people do not understand this and will never understand until it happens. Although even this will happen, there will still be no understanding, it will be too late. Here's an elementary example. Now in most stores sellers use computers to sell goods. And then a failure occurred and the computer stopped working, which resulted in the sale of goods stopped and a huge queue formed. There are a lot of such examples. That is, the digital world depends on the availability of energy and can not live without this factor. However, there is no guarantee that the energy will always be, since there are always possible accidents and other negative factors. Question: What to do when this happens? Could we go back to the traditional life without computers? However, the tragedy is that people will no longer be able to live without computers and this factor will make most people unhappy ones with the tragical consequences. The Digital Economy can lead to a complete loss of the sovereignty of the country, and this is already a pure policy in the era of Globalization. Maybe it is for this reason that the Stars of the Digital Economy try to lit? Who tries to lit - maybe the so-called Global Elite, which chooses and appoints presidents of countries, and people approves this choice in so-called democratic elections. Only one important thing is that democratic elections will never use electronic voting, since presidents are already were appointed from above.
