Achieving high-quality economic development under the background of the new era is the key to building a beautiful China. Based on the panel data of 108 cities in the Yangtze River Economic Belt from 2003 to 2016,the ML index and the Dagum Gini coefficient method were used to measure and analyze spatial-temporal evolution and regional disparity of economic quality,efficiency change and technological change. The results show that the economic quality,efficiency changes and technological changes are growing at an average annual rate of 2.48%,-0.53%,and 3.03%,technological progress is the driving force for the optimization of economic quality. The economic quality of the upper,middle and lower reaches shows periodic fluctuations over time,the average economic quality of the downstream is the highest,followed by the upstream and the lowest in the midstream. The spatial distribution pattern of high-value areas of economic quality has evolved from upper and lower areas to middle and lower reaches,the high-value area of efficiency change is a spatial agglomeration pattern of the middle reaches of the Yangtze River and the Yangtze River Delta urban agglomeration,high-value areas of technological change are distributed in the middle and upper reaches. The overall regional disparity in economic quality,efficiency change,and technological change has expanded,and the inter-regional gap is the main cause of the overall regional disparity.
