Coordinated development is an important part of the new development concept. Continuously enhancing the integrity of development is also an inherent requirement for high-quality development. Coordinated development itself has very rich connotations. By decomposing coordinated development into regional coordination，urban-rural coordination，material civilization and spiritual civilization，economic development and social development，economic construction and ecological construction，this report has established the coordinated development of China’s economy. Evaluation index system. It is estimated that China’s coordinated economic development index will reach 67.05 in 2020，an increase of 17.45 from 49.60 in 2001. In terms of different fields，the regional coordination index in 2020 is 28.20，the urban-rural coordination index is 20.07，the material civilization and spiritual civilization coordination index is 3.08，the economic development and social development coordination index is 5.19，and the economic construction and ecological construction coordination index is 10.51. The coordination index has been improved to varying degrees in the past 20 years. In terms of subregions，in 2020，the level of coordinated development of various regions across the country will have relatively small gaps. The level of coordinated development of developed regions has weak advantages over underdeveloped regions. The performance of various regions on the secondary indicators of coordinated development is clearly differentiated. The level of coordinated development of Underdeveloped regions in the past 20 years has been improved more than that of developed regions. Based on the above analysis and conclusions，this report proposes that to further improve the coordinated development of China’s economy，we should continue to promote the coordinated development of regional，economic and ecological construction，and at the same time，we must focus more on promoting the coordinated development of urban and rural areas，and the coordinated development of economy and society. As soon as possible to make up for the shortcomings of the coordinated development of material civilization and spiritual civilization. It is necessary to comprehensively deepen reforms to remove institutional and institutional obstacles that hinder coordinated development. It is necessary to promote the development of developed regions to improve the integrity and balance of internal development，and at the same time promote the development of underdeveloped regions to accelerate the cultivation of growth poles with strong linkages.
