Quantitative Analysis of Regional Economic Balance and Sustainable Development in Yangtze River Delta and Pearl River Delta

This paper selects the per capita gross national product (GDP) and per capita marine product (PGDP) of the Pearl River Delta and the Yangtze River Delta from 2011 to 2016 as economic indicators, and analyzes the quantitative analysis of regional economic balance and sustainable development. Taking the water quality area proportion as the pollution index, combined with the possibility and form of the existence of the Marine Environment Kuznets curve (EKC), through quantitative analysis, it is found that there is no uniqueness between the balance of economic development and the aggravation of marine pollution. The contradiction between marine pollution control and regional economic development is not prominent. The active control of marine pollution has become the premise of the balanced economic development of the Yangtze River Delta and the Pearl River Delta.
