By constructing an evaluation system based on emergy analysis which included emergy flow, source of emergy index, social subsystem evaluation index, economic subsystem evaluation index, natural subsystem evaluation index and composite index, the development and sustainability of the eco-economic system of Liaoning Province between 2000 and 2010 were evaluated. The result showed that from 2000 to 2010, the total used emergy increased from 3440.12 x 10(20) sej to 7636.33 x 10(20) sej, among which the proportion of the nonrenewable emergy in 2010 occupied the most in the total by 68.6% , and the emergy per capita increased from 8.32 x 10(15) sej to 17.96 x 10(15) sej. The emergy self-support ratio in the system was generally higher, while it dropped from 91.1% in 2000 to 79.9% in 2010. The emergy loading ratio increased from 3.22 to 7.80, the emergy sustainable index dropped from 3.47 to 0.64, and the emergy index for sustainable development decreased from 6.73 to 1.56. It suggested the eco-economic system of Liaoning Province presented an unsustainable development trend. The development level of Liaoning in 2010 merely equaled to the level of Japan and America in the 1980s.
通过构建基于能值分析的评价体系，该体系包括能值流、能值来源指标、社会子系统评价指标、经济子系统评价指标、自然子系统评价指标和综合指标，对2000年至2010年辽宁省生态经济系统的发展与可持续性进行了评价。结果表明，2000年至2010年，总使用能值从3440.12×10²⁰sej增加到7636.33×10²⁰sej，其中2010年不可再生能值在总量中占比最大，为68.6%，人均能值从8.32×10¹⁵sej增加到17.96×10¹⁵sej。系统的能值自给率总体较高，但从2000年的91.1%降至2010年的79.9%。能值负载率从3.22增加到7.80，能值可持续指数从3.47降至0.64，可持续发展能值指数从6.73降至1.56。这表明辽宁省生态经济系统呈现出不可持续的发展趋势。2010年辽宁的发展水平仅相当于日本和美国20世纪80年代的水平。
