Abstract: From the five aspects of ecological protection, environmental governance, innovation driven, economic development and people's livelihood improvement, the paper constructed a high quality development index system of Inner Mongolia autonomous region, and used entropy weight method to measure and analyze the high quality development of Inner Mongolia autonomous region from 2009 to 2018. The results show that, in terms of ecological environment, although there is fluctuation in Inner Mongolia, the overall trend is good. In terms of innovation driven, although Inner Mongolia has been fluctuating, its innovation ability is still insufficient.In terms of economic and people's livelihood, Inner Mongolia shows a trend of fluctuating growth, and its development trend continues to be good. In general, the high quality development level of Inner Mongolia autonomous region is fluctuating upward. Inner Mongolia autonomous region should fully grasp its own advantages, strengthen regional innovation and development, and fully exploit regional development potential.

Key words: high quality development level, measurement, entropy weight method, Inner Mongolia autonomous region
