China has made rapid progress in quality development since the implementation of the "Quality Development Outline (2011-2020)". To evaluate the efficiency of quality development, a Quality Development Efficiency Index (QDEI) was constructed based on the data of two international institutions, the World Economic Forum and the International Institute for Management Development. The index includes 4 target indicators, i.e., product quality, service quality, engineering quality, and environmental quality, and 12 process indicators with close relationships with "Quality Development Outline". Some conclusions can be summarized based on the index analysis. Firstly, in the last decade, China's quality development can be summarized within three phases, i.e., a stationary phase, a promotion phase, and an acceleration phase. Secondly, the engineering quality and the product quality have developed and attained a higher level in the world, but the overall development of the four kinds of quality is not balanced and has not achieved simultaneous improvement. Thirdly, there is much difference in the implementation performance of different policies on quality. Especially, it is significant to make effort in technological innovation and the construction of multiple remedies for quality safety. Based on the research results, some suggestions were proposed for future work on quality development in China.
