What is an integrated economy?

This is a concept put forward in the book Economics of Necessity. Its basic connotation refers to the increasingly close relationship between global economies in 2 1 century. This close relationship not only produces huge economic energy like nuclear fusion, but also makes the world economic problems more complicated. In this case, no country can solve these problems alone, and it must rely on the full cooperation of all countries in the world to ensure the stability and sustainable development of the world economy.
