Abstract:Three optimization paths for innovation and entrepreneurship based on the “double innovation” ecosystem were proposed. This study selects the development status of innovation and entrepreneurship environment about some provinces in the top 15 of China's Regional Innovation Capability Evaluation Report 2018, and builds a seven-dimensional indicator system including economic development and government support, industrial development,and etc. On this basis, two methods of fuzzy-set qualitative comparison analysis and coupling analysis are introduced. The results prove that there are three environmental optimization paths of “industry-led”, “culture-driven” and “environmentally coupled” in the construction of “double-creative” ecosystem. Taking the optimization of “double creation” environment in Shaanxi province as an example, this study analyzes the current status and existing deficiencies of the “double innovation” environment, and explores the optimization path and mode of innovation and entrepreneurship environment in Shaanxi province based on the “double creation” ecosystem construction, which can provide reference for the promotion of the “double innovation” upgrade.
