协调度理论已成为研究区域经济发展与环境保护耦合程度的重要理论.本文在阐述其理论的基础上,建立了经济环境协调度的指标体系、模型和计算方法.通过对辽宁省14市10年各项指标数据的技术处理和分析:辽宁省1996-2005年经济环境协调度整体处于调和阶段,在空间分布上,协调度值高的城市大都分布在南部沿海地区,协调度值低的大部分在辽宁省东部和西部;1996年以来辽宁省经济环境协调度的发展趋势呈“V”型变化,“九五”向“十五”过渡阶段协调度最低;经济环境协调度与经济发展阶段符合“U”型曲线,工业化初中期即第二经济发展阶段的协调度最低;1996-2005年期间14个市的经济环境协调度呈现出不均衡发展,其中大连市的协调度值较高.最后,本文认为应以大连市为龙头,与其他协调度值较低的城市实施区域合作战略,从而达到全省各市的经济发展与环境保护协调同步.

The theory of the coordination degree has been viewed as an important way to research the degree of coupling between the regional economic development and environmental protection. Many studies about the coordination degree between economy and environment effectively identified whether the relationship between economy and environment was in the state of coordination. Although some researchers have done lots of studies, it is still a disputable question how to make a rational assessment of the degree of coupling between economy and environment.Based on the theory, this paper established an indicator system, a model and a calculating method for the coordination degree. Through technological treatment and analysis of ten-years′ data of the 14 cities in Liaoning Province, the article made an attempt to assess the coordination degree between the economic growth and the conservation of environment. Many conclusions were obtained as follows: the coordination degree between economy and environment in Liaoning Province was generally situated in the stage of reconciliation from 1996 to 2005, while in the spatial distribution, the cities with the higher value of the coordination degree mainly were located in the southern coastal areas and those with the lower value of the coordination degree were mostly in the eastern and western parts of Liaoning Province. The evolutional trend of the coordination degree between economy and environment in Liaoning Province was a "V-shaped" curve since 1996, and the coordination degree had the lowest value of the transitional stage from the ninth five-year plan to the tenth. The relationship between the economic development and coordination degree was in line with a "U-shaped" curve, and the lowest value of the coordination degree value occurred in the Ⅱ stage of the economic development which was the initial and middle periods of industrialization. The coordination degrees of the 14 cities presented an unbalanced development from 1996 to 2005, and among these cities Dalian held a higher value of coordination degree. These conclusions will help the government to understand and forecast the developing trend in the coordination of each city in Liaoning Province, so as to adjust it on time and to avoid the economic growth relying on the deterioration of resources and environment. Finally, this paper suggested that, taking Dalian as a "cock", it should carry out regional cooperation strategies with the other cities which had far lower values of coordination degree, in order to reach the state of coordination for each city of Liaoning Province between the economic development and the environmental protection. The detailed measures included technological support about the conservation of environment, the assistance of the economic and environmental professors, and the funds offered to develop the regional economy and protect the ecological environment.
