The characteristics and countermeasures of coupled and coordinated development between technological innovation and ecological environment in China’s Gansu province

The investigation of the coupling and coordination association between scientific and technological innovation and the eco-environmental system is of vital practical significance for promoting the high-quality economic development of China’s Gansu province. The evaluation index system is constructed based on the explanation of the coupling and coordination mechanism of a “Binary system”. Subsequently, a comprehensive evaluation model is developed using the entropy method, whereas the coupling coordination relationship between “Binary systems” is analyzed in the context of the coupling coordination degree model. The study findings indicate that the innovation drive has become the primary driving force that leads the high-quality economic development in Gansu province. Furthermore, the comprehensive development level and coupling and coordination degree of all systems in Gansu province demonstrate a sound trend of steadily rising. Additionally, there is an issue of uncoordinated development between scientific and technological innovation and eco-environment systems in Gansu province. Thus, this research study proposes certain policy suggestions, such as optimizing the environment of Sci-tech innovation, insisting on the priority of ecology, increasing the input of Sci-tech innovation, and building up a contingent of talents.
