Using new improved entropy Right-TOPSIS（technique for order preference by similarity to ideal solution）model, Chinese manufacturing high quality development level from 2012 to 2020 was evaluated, the dimensions were analyzed, and the timing evolution characteristics of manufacturing development of high quality were summarized. Spatial analysis method was used to study the spatial distribution characteristics and evolution trend, and with the help of the Thiel index and its decomposition method, the development of the manufacturing high quality regional gap was studied. The results show that the overall level of high-quality development of China's manufacturing industry is increasing, in the region, from the stability of the central region, the western region and the eastern region，from the spatial evolution analysis, there is some spatial agglomeration，from the regional gap, the overall gap of the manufacturing industry is increasing and then decreasing, and the regional difference is the main source of regional differences, and the eastern region is the main contributing region of the regional difference.
