"Guangzhou-Shenzhen" Urban Linkage and Cooperation Study

As important cities in the Guangdong-Hong Kong-Macao Greater Bay Area, the development of Shenzhen and Guangzhou is of great significance for achieving resource complementarity and promoting industrial synergy in the region. Based on data from 2002 to 2022, this paper uses the Euclidean distance measurement algorithm to calculate the gravitational strength between the two cities, and assesses their competitive and complementary relationships through the geographical affinity strength. Combining these relationships, this paper analyzes the directions in which the two cities can achieve complementary development in the future three industries, and proposes suggestions for optimizing their industrial structures and improving government policies.
