Countries are at different stages of development. Global cooperation on production capacity will match supply with demand effectively, and generate more demands through innovation on the supply side. As developing countries accelerate industrialization and urbanization, they now have a strong demand for applicable technologies, equipment and infrastructure. Many middle-income countries and developed countries also need to upgrade their equipment and infrastructure. However, constrained by funding shortage, some demands have been repressed. Talking about comparative strengths, developed countries have advanced key technologies and equipment, but the demand for their products and equipment is limited due to high prices. Developing countries may enjoy rich natural resources and low labor costs, yet most of their industries and products are at the low end.
