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

摘要： 研究经济发展、科技创新与生态环境系统之间的耦合协调关系,对推进陕西省经济高质量发展具有重要的现实意义。在阐述“三元系统”耦合协调机制基础上,构建了评价指标体系。综合运用灰色关联理论和熵权法建立了综合评价模型,基于耦合协调度模型研究了“三元系统”之间的耦合协调关系。研究发现:创新驱动成为引领陕西省经济高质量发展的第一动力,各系统综合发展水平和耦合协调度稳步上升,但系统之间依然存在发展不同步、不协调问题,生态环境系统成为制约高质量发展的短板。
