Study on the Measurement of Regional Economic Connection in the Pearl River Delta

摘要

The process of regional economic development is a process in which regional economic connections are continuously strengthened. This paper uses gravity model to measure the economic connection strength and total strength of cities in the Pearl River Delta from 2000 to 2017, and then calculates the economic connection strength within the region, and analyzes the historical trajectory of economic connections in the Pearl River Delta. The results show that the total strength of economic connections between the cities in the Pearl River Delta keeps going up, forming the Guangzhou-Foshan-Shenzhen area with the strongest total strength of connections, Dongguan-Zhongshan-Jiangmen area with strong total strength and Huizhou-Zhuhai-Zhaoqing area with weak total strength. The economic connection difference between the east and west sides of the Pearl River Estuary have been gradually widened, and the situation of strong east and weak west is constantly strengthened.
