As a special policy area under China's new normal economic background, the National New District plays a key role in the realization of economic and social development and green growth. This paper constructs an evaluation index system for green growth capacity from five aspects: government support capabilities, corporate green capabilities, NGO supervision and guidance, public participation capabilities, and park output benefits. Various methods are used to measure green growth capacities of these four National New Districts including the Jinpu, Pudong, Binhai, and Nansha. The results show that government support capability has the greatest impact on the green growth capacity of the state-level new district and Pudong has the largest green growth capacity, followed by Binhai, Nansha and Jinpu.
