Why is China's e-commerce index predicting Trump's election?

Not long ago, there must have been many people who have followed the US election. The result of this election is a drop in the glasses. Because all the media think that Hillary will win before the election, they think that Trump is a weak party, but the result is Very different.

In fact, as early as three months ago, we Chinese people already have some data that can predict this result.

Before Alibaba, Alibaba compared the propaganda materials purchased by the fans of the US presidential candidates. The red line is Trump's. His fans bought hats, masks, slogans, etc.; blue is Hillary, you will The enthusiasm of the two groups of supporters was found to be different.

In this US election, only 55% of the legitimate voters voted. The key factor for Trump's victory is that the people who support him are more fanatical than those who support Hillary, and they all vote.

Alibaba's data can be seen three months ago, and finally Trump won, so the data can tell us a lot of wisdom. The amount of data today is already very large. In terms of bytes, it has surpassed the sum of all the atoms in the solar system. If we can use these big data well, we can give us a lot of new information and knowledge. .

This is an image drawn by an American scientist comparing the per capita income and average lifespan of many countries from 1800 onwards. Each dot above corresponds to the average national income and average life of a country for one year. The yellow dots represent the United States and the red dots represent China. The US data began in 1802. In fact, the starting point of the United States is very similar to that of the Chinese. It has been stagnant for many years. From this picture, it can be seen that while its national income continues to grow, it The average life expectancy of the nation has not changed much, it has been flat.
