Abstract: It is of great significance to study the coupling relationship between economic development, technological innovation and ecological environment systems to promote high-quality development. On the basis of expounding the coupling coordination mechanism of ternary system, the system evaluation index system is constructed. A comprehensive evaluation model is proposed by using grey correlation theory and entropy method. Coupling degree and coupling coordination degree model are introduced to study the coupling coordination relationship among economic development, technological innovation and ecological environment system. This paper empirically analyzes the comprehensive development level, grey correlation characteristics and coupling coordination degree of the ternary system in Shaanxi Province. The results show that: innovation driven became the first power to lead the high-quality development of Shaanxi Province. The comprehensive development level and coupling coordination degree of each system have risen steadily, but there are still problems of unsynchronized and uncoordinated development among the systems.

Key words: economic development, technological innovation, ecological environment, coupling coordination degree
