摘要
在经济高质量发展的背景下,轨道交通产业也应从高速发展转向高质量发展,需对其高质量发展水平构建指标体系.利用灰色粗糙集理论对成都市轨道交通产业高质量发展评价初选指标体系进行约简,从"创新、协调、绿色、开放、共享"五大方面构建了成都市轨道交通产业高质量发展评价指标体系.结果表明,运用灰色粗糙集理论可以对成都市轨道交通产业高质量发展评价指标进行有效的筛选.
In the context of high-quality economic development,rail transit industry should also shift from high-speed development to high-quality development,so it is necessary to con-struct an index system for its high-quality development level.Gray-rough set theoryis used to reduce the primary evaluation index system of high-quality development of Chengdu rail transit industry.The evaluation index system of high-quality development of rail transit in-dustry is constructed from five aspects of"innovative development,coordinated development,green development,open development and shared development".The results show that the gray-rough set theory can be used to reduce the indexes effectively.
