Research on Industrial Agglomeration and Isomorphism of Manufacturing Industry in Pearl River Delta

As a national strategy, the construction of Guangdong-Hong Kong-Macao Greater Bay Area is of great significance. The Pearl River Delta is one of the core regions of the Guangdong-Hong Kong-Macao Greater Bay Area and important for the upgrading of innovative manufacturing industries. It is important to enhance the competitiveness of those areas and optimize industrial structure by promoting the division of labor between cities. The quantitative research on the industrial agglomeration and industrial isomorphism of the manufacturing industry in nine cities in the Pearl River Delta shows that each city has formed its specialized manufacturing industry, and the phenomenon of industrial isomorphism has been improved by the unified planning of the manufacturing industry in the Pearl River Delta.
