| 摘 要： | 科学地评价循环经济发展是进一步推进循环经济发展的决策依据。本文从辽宁省循环经济发展为例，运用能值分析方法从能值流量、资源投入产出、资源消耗、环境压力、综合指数五个方面构建了循环经济评价能值指标体系，详细分析了辽宁省1990年-2005年循环经济发展状况。结果表明：辽宁省经济发展主要依赖于本地资源，需要购买的能值总量较少，资源基础相对雄厚，总能值用量中74％以上来自不可更新资源消耗，且逐年上升。经济活动造成的环境污染越来越严重，虽然废弃物能值增长幅度滞后于总能值用量与GDP增长幅度，说明资源利用效率的提高和污染排放治理工作成效显著，但传统粗放型经济增长模式的惯性作用，使废弃物总量持续增加状况在一定时期内还将继续存在，系统可持续发展的能力不断下降。因此，辽宁省发展循环经济要立足于不可更新资源的合理使用，降低废弃物排放，加强资源的循环利用，促进人与自然的和谐发展。

| Abstract: | Scientific evaluation of the development of circular economy is the decision-making foundation to further promote circular economy. In this paper, Liaoning Province was selected as study area to draft the judgment model of regional circular economy. Using emergy analysis, the development of circular economy in Liaoning was evaluated from such five aspects as energy flux, resource input and output, resource consumption, environmental pressure and comprehensive index. The paper analyzed the development of circular economy in Liaoning from 1990 to 2005 in order to conduct background analysis and probe into the method and theory of circular economy. Results showed that: 1) The total energy input of nonrenewable resource in Liaoning province increased 2.38 times during the period of 1990 to 2005, occupying 74% of the total energy used. Obviously, the current rapid economic growth in Liaoning province was derived at the cost of vast nonrenewable resource consumption. At the same time, the increase rate of total wasted energy was lower than that of total energy, which implying the significant improvement of resource use efficiency and considerable achievements in circular economy; 2) The ratio of self-supplying energy decreased from 98.5% to 89.5%, which indicating that economic growth in Liaoning province primarily depended on local resource with a relatively strong resource foundation and a higher energy safety. Both the ratio of output per unit resource and the ratio of output per unit energy presented a decreased tendency, which implying that economic growth in Liaoning province consumed a great of nonrenewable resources; 3) The consumption of energy, electricity and water resources per ten-thousand-Yuan GDP also showed significant decreasing tendency, which implying the obvious progress made in cleaner production, construction of ecological industry chain and energy and resources recycling; 4) The index of Energy sustainability in Liaoning province decreased significantly, which indicating the rapid economic growth caused the great consumption of nonrenewable resource and continuous decrease of sustainable development capacity. Energy index of circular economy in Liaoning was lower than index of energy sustainability, which implying a gradual improvement in resource utilization and pollution reduction. |
