COORDINATION DEGREE OF ECONOMIC AND ENVIRONMENTAL SYSTEMS' DEVELOPMENT IN CHINA
构建了评价环境与经济综合协调发展的指标体系，测度了中国东中西部地区的环境与经济协调发展度，为区域经济可持续发展及相关政策实施提供科学依据。
Because the development degree's coordination of regional environment and economic systems has a high degree of complexity, uncertainty, and the multilevel nature, it is difficult to quantify, so it has become a hot issue of current research. In this paper, summing up the results of existing research, the index system is built to evaluate the environmental and economic comprehensive and coordinated development. And the coordinated development degree of the environment and economy in China's eastern, central and western regions is comprehensively measured, which provide a scientific basis for spatial and temporal comparison with regional economic sustainable development and the implementation of the related policies.
