Research on Coordinated Development of Jiaodong Urban Agglomeration

Regional coordinated development has always been an essential strategic deployment in China. Since the 18th National Congress of the Communist Party of China, the Party Central Committee has placed regional coordinated development in a more crucial position and included it in the national five-year development plans multiple times. The Jiaodong Economic Circle is the most dynamic region for economic development and opening-up in Shandong, representing the province's strategic planning for deepening the transformation of old and new driving forces and promoting high-quality development in the Yellow River Basin in the new era. This paper employs various methodologies, such as the Gini coefficient, market integration index, gravity model, and the degree of specialization in marine industries, to examine the level of coordinated development among the five cities in the Jiaodong region, and offers corresponding suggestions.
