经济与环境协调发展是促进地区经济快速发展的重要保障。本文首先通过计算各地区经济与环境综合指数,测算了各地区过去10年经济与环境发展协调度。结果表明,我国大部分地区都处于弱协调和比较不协调状态,东部地区协调性最高,中部地区协调性变化较平稳,西部地区协调性变化起伏较大,特别是近几年协调性没有明显好转。其次,将协调度作为输入约束,分别测算了各地区经济系统和环境系统发展综合效率。从全国平均来看,两系统综合效率比较接近,说明两系统基本是耦合同向发展。从各地区分布来看:东部沿海经济区、长江中游经济区、南部沿海经济区两系统效率较高,但处于效率前沿面的地区太少;西北经济区、西南经济区经济系统效率较低;西北经济区、黄河中游经济区、东北经济区环境效率很低;另外,环境系统的效率水平分布不均匀,环境治理的溢出效应有待进一步提升。 The coordinated development of economy and environment is an important guarantee to promote the rapid economic development in the region. In this paper, first, by calculating the comprehensive index of economy and environment in each region, we calculate the coordination of economic and environmental development in each region in the past 10 years. The results show that most of China’s regions are in a state of weak coordination and uncoordination, the coordination of the eastern region is the highest, the coordination in the central region changes more smoothly, and the coordination of the western region has a great fluctuation. In particular, there is no obvious improvement in coordination in recent years . Secondly, using the coordination as the input constraint, the comprehensive efficiency of the economic system and environmental system in each region are calculated separately. From a national average point of view, the overall efficiency of the two systems is relatively close, indicating that the two systems are basically coupled and co-developed. According to the distribution of different regions, the eastern coastal economic zone, the middle reaches of the Yangtze River and the southern coastal economic zone are more efficient, but the areas at the front of efficiency are too few; the economic systems in the northwest economic zone and the southwest economic zone are inefficient; Northwest Economic Zone, the Yellow River Economic Zone, Northeast Economic Zone, the environmental efficiency is very low; In addition, the efficiency of the environmental system is unevenly distributed, environmental management spillover effects need to be further improved.
