It is of great practical significance to measure the level of high-quality economic development and make regional research on it for realizing the new pattern of development under the background of common prosperity. Based on this, First, this paper takes the data of East China from 2014 to 2019 as the research object, and considers the five development concepts of innovation, coordination, green, open and sharing to construct the index system of high-quality economic development of East China, then use the Critic and Comprehensive Index Law to measure the high -quality economic development level of East China. In addition, this paper uses the Theil index, coefficient of convergence and coefficient of variation have performed the level of time and space to analyze the level of high-quality economic development. The empirical results show that the quality of green development and the quality of open development have contributed the greatest increase in the level of high-quality development in East China. At the same time, the comprehensive index of high-quality development of the provinces in various provinces has shown an upward trend, the coordinated development between provinces and the pace is gradually consistent, but the differences in the same dimension in different provinces are large. Based on the conclusion of the appeal, relevant countermeasures and suggestions are put forward for realizing the high-quality economic development in East China under the new pattern.
