Abstract: The idea of coordinated development has a long history. Development refers to the system from disorder to order, small to large, weak to strong, and low to high. Coordination refers to the interaction of various forces to achieve a positive linkage. Based on the economy, social technology, resources and ecology comprehensive evaluation index system and the coordinated development degree model to measure the coordinated development of 31 provinces in China, the study finds that the current development of China provinces has problems such as a large gap in regional coordinated development, the low level of four-dimensional system construction, and inconsistency between coordination and development. In order to achieve long-term stable development in China, we must take measures such as promoting close cooperation between regions, further strengthening the construction of the four-dimensional system, and achieving a healthy symbiosis of coordination and development.
