Research on the construction of independent innovation capability in China based on grey comprehensive evaluation

The study aims to research the effecting factors of the level of independent innovation ability in China, constructing innovation environment by the grey clustering model and build the national innovation capability evaluation index system, including the innovation input, innovation output and innovation potential of 4 indexes and 17 level two indexes. The related data of 26 countries was collected as sample and the center point of improved hybrid triangle whiten the function was used to divide area to four regions from the perspective of independent innovation ability based on the construction. This method provides the basis for the localization of independent innovation ability level of China, and finally finds out the reasons of China's independent innovation capacity development and puts forward relevant suggestions.
