The characteristics are as follows:

1. The United States has a great advantage in the innovation base of technology, technological capabilities, and the influence of technology. China is in the application of landing, application innovation has a unique advantage, such as brush face payment, is China's first.

2. Today's AI technology includes three elements: data, algorithms, and computing power. China has an advantage in data, because of the huge size of the population, China is much ahead of the United States in collecting data from all parties and statistics.

Algorithms, the gap between China and the United States is not very large, although the United States tends to put forward innovative technology, but China is able to quickly keep up with it, although the technological innovation leadership is a little weaker, but the gap between the actual application is not large.

The main gap is in the basic computing equipment. Because whether to do training or detection, hardware equipment is necessary, these devices are not limited to artificial intelligence itself, but also involves the hardware chip GPU. training of artificial intelligence, deep learning algorithms often need a graphics card, GPU is now monopolized by Nvidia a global, the other necessary hardware is the CPU, in the field of CPU, Intel a dominant.

There are also sensors, training artificial intelligence, first of all to perceive the surrounding environment. Sensors include radar, which is very important in the application of autonomous driving, and these hardware devices are almost all monopolized by U.S. companies. So, it creates a not-so-small gap in hardware.

3, the lack of breakthrough leading innovative technology, many Chinese companies are more oriented to the application, favoring the business model of the application of innovation. Every time the United States to come out of the new technology, China can also immediately follow up, but in the leading, breakthrough may still have a certain gap.

4, the United States from the earliest sprouted in 1991, 1998 into the development period, 2005 after the beginning of the high-speed growth period, 2013 after the development of stabilization. While Chinese AI companies were born in 1996, the industry entered the development period in 2003, and reached its peak in 2015 after entering a stable period. Artificial intelligence is mainly divided into technology layer, application layer and foundation layer.

The U.S. AI industry has accumulated a strong technological innovation advantage in the foundation layer, technology layer and application layer, especially in the core areas of the industry such as algorithms, chips and data, and the number of enterprises in each layer is comprehensively ahead of China.

From the point of view of the number of enterprises in the foundation layer (mainly processors/chips), China has 14 and the United States 33, with China being only 42% of the United States; in the technology layer (natural language processing/computer vision and image/technology platform), China has 273 and the United States has 586, with China being 46% of the United States.

Application layer (machine learning applications/intelligent drones/intelligent robots/autonomous driving assistance/speech recognition), China has 304, the United States has 488, China is the United States 62.3%.

It can be seen that, compared with the U.S. characteristics of the whole industry layout, China is mainly focused on the application side, in addition to the technology layer and the basic layer is only a local breakthrough.

In summary, at present, in the field of artificial intelligence, China in general, although there is a certain gap with the United States, but is still in a relatively good development trend.
