Abstract：The ecological fragile zone of Loess Plateau is located in the intersection region between many different ecological regions where the ecological environment is vulnerable and will spend a very long time to recovery. For the particularities of ecological fragile zone， the cities situated in these regions will face more problems and questions on the way to follow the innovation development and high-quality development call. 24 cities from 7 provinces from 2012 to 2018 in the Loess Plateau ecological fragile zone are chosen as object， and the DEA-Tobit model is used as evaluate model to measure innovation efficiency and factors which might be important on innovation efficiency. The ArcGIS is utilized to visualize the spatio-temporal evolution pattern of efficiency change. It's concluded that the city innovation efficiency in the Loess Plateau ecological fragile zone shows an unbalanced development in space with significant spatial differences.The efficiency is growing by time， and some cities exhibit rapid growth tendency.It's found that 16 cities reached the optimal efficiency in 2018. For the influence factor evaluation model results， the education level and economy growth have positive effects on regional innovation efficiency， while unreasonable industrial structure and fiscal expenditure have negative effect on regional innovation efficiency. Finally the advice are as follows.1) The local government should ensure the implementation of policies related to scientific and technological innovation.2) The synergistic development of environmental protection and economic development should be effectively promoted.3) A long-term effective environmental protection and restoration mechanism should be established for ecological compensation. 4) Attention should be paid to the three major projects on the Loess Plateau， and innovative engineering technologies should be implemented to reduce the damage on environment. These suggestions will provide reference in sustainable development and high-quality development for environment fragile zone.
