Abstract: Abstract: On the background of regional economic integration and eco-environment developing being researched as a popular topic, how to coordinate the two systems includes the sustainable development of a country or region. Especially the coupling and harmonious development is a key issue in the sustainable development. On the basic of 20 indicators of the two systems and through employing models of coordination degrees and method of weighted entropy value, the paper evaluates the regional economic integration level and eco-environment level from 1991 to 2010 at the national level. The result shows that the process of regional economic integration has being speeding up in the recent 20 years, the level of ecology and environmental reveals a general fluctuation trend of “one up and one down and one up”. While the coupling and coordinated degree has achieved the stable and continuous improvement. In the provincial research scales, the paper analyzed the regional economic integration and eco-environment coupling and coordinated development in China’s 31 provinces in 1991, 2000, 2010 at the time-space dimensions. The results show that the levels of regional economic integration and eco-environment systems and the coupling degree exist obvious regional difference.

摘要： 摘要：在区域经济空间一体化和生态环境发展这两个问题日益成为研究热点的背景下，如何协调二者的关系涉及到一个国家或地区能否实现可持续发展，二者之间的耦合协调发展更是实现可持续发展的核心。本文基于两个系统20个指标构成的评价指标体系，通过耦合协调度模型和熵值法，首先从全国研究尺度上对于1991~2010年的区域经济空间一体化水平与生态环境水平进行评价，结果显示近20年中国区域经济空间一体化进程加快，生态环境水平总体上呈现出“先升后降”的变化趋势，二者的耦合协调程度实现了稳定和持续的提高。在省域研究尺度上，对1991年、2001年和2010年31个省级地区的区域经济空间一体化和生态环境耦合协调发展进行时序和空间两个维度的实证分析。结果表明，各省的区域经济空间一体化与生态环境水平以及二者交互作用的耦合协调度存在明显的区域差异。
