Abstract: Based on import and export trade data and commodity data, this paper has studied the manufacturing trade network and its production process in east Asia since 2003. According to the import and export trade network, whether it is labor intensive or capital (technology) intensive products, China's participation is higher than those South-east countries. With the development of southeast Asia countries, they have gradually become involved in the division of labor, and trade links have gradually increased. From the production process of the product, it is obvious that the early "triangle trade" phenomenon is obvious, especially the high technical content of land transportation; Second, southeast Asian countries have strong dependence on big countries, especially capital (technology) intensive products; The last, small area of the region is gradually strengthened, especially in emerging countries such as Thailand and Malaysia. Not only are the results verify the trend of product network, but also can provide theoretical services for the industrial upgrading of some East Asia countries.
