5.1 Evaluation of the GFG implementation
In the Loess Plateau of China, the primary goal of GFG is to curb the increasingly severe soil erosion, thereby reducing the sediment content in the Yellow River. As an ecological policy, the GFG has had a positive and far-reaching impact on the ecological environment in relevant regions over the past 20 years. Yan’an is considered to be one of the cities with the most serious soil erosion in the Loess Plateau. The vegetation restoration brought by GFG has significantly controlled soil erosion in the city. However, the research in this paper shows that although the GFG plays an obvious role in soil conservation, there are problems of policy dislocation and low efficiency in the specific implementation process. In some areas, the implementation of GFG has cost a lot, but the SCE is very limited. This not only exposes the external manifestation of local government’s one-sided pursuit of vegetation restoration effect in the process of policy implementation but also reflects the failure of the superior government to make sufficient analysis and judgment on the key implementation regions of GFG in the process of macro-control. The result is an imbalance in input and output, and a waste of resources and capital. These problems need to be adjusted and changed in the future. It also shows that the implementation of GFG in the future still has great significance.
