China, Japan, the United States and other countries are all part of the international industrial supply chain. Especially, the closer the regional cooperation, the greater the connection in the supply chain. Vertically, China is an upstream and midstream industrial country, providing resources and labor in the upstream and manufacturing and equipping finished products in the midstream, while Japan and the United States are downstream industrial countries, mainly end-user countries. But this does not mean that China is the workshop of the world. In fact, China is only the world's processing factory. Processing technology, high-end equipment, important parts and so on need to be imported from Japan and the United States. And the most important processing standards are also formulated by Japan and the United States! China is just a wage earner! China relies on Japanese and American domestic markets! Japan and the United States have huge markets and strong purchasing power. Although China has a population of 65.438+0.3 billion, its market purchasing power is not as big as that of Japanese. In other words, China's domestic demand is insufficient, and China's domestic consumption cannot stimulate economic growth. Need exit pull. Moreover, this kind of export is not a high-end export from Japan and the United States, but a low-end export. To put it bluntly, China works for Japan and the United States.
