摘  要
 经济全球化已经成为一种不可逆转的趋势，正在将世界各国卷入其中，复杂激烈的竞争成为当前及未来时代的基本特征。决定竞争胜负的因素由几个单一的要素变为一个复杂的要素体系，并且起决定作用的要素正在发生着根本性的变化。城市在全球化经济中处于突出而无可替代的位置。因此，在全球化背景下讨论城市竞争力具有广泛的理论和现实意义。正确认识和评价辽宁省城市竞争力，有助于我们正确认识自身处境，认识竞争对手、合作伙伴的优劣势，并制定正确的竞争与区域合作战略，从而有助于城市合理有序的竞争、充分积极的合作，有利于推动区域经济的合理发展。它能使我们更清楚所面临的情况，加快振兴步伐。
 本文首先从城市竞争力理论基础谈起，追溯城市竞争力的研究起源，并在总结前人研究的基础上，给出城市竞争力的定义，同时对城市竞争力的内涵及其影响因素进行了分析；然后分析辽宁省各城市的发展状况，结合前述的影响因素，建立了评价模型和指标体系；之后分析各评价方法的优劣，得出主观评价方法指标权重的确定主观性较强，而客观评价方法大部分无法对冗余指标进行删除的结论，并因此引入粗糙集理论，对城市竞争力评价中的连续属性进行离散化，运用粗糙集理论对指标体系进行简化，并对简化后指标体系中的指标权重进行计算，最后得出综合评价结果；最后根据分析结果并结合实际，分析出目前阻碍城市发展所存在的问题，并针对各城市的具体情况提出提升辽宁省各城市竞争力饿政策建议。

Abstract
 The globalization which is a trend cannot be reversed, is effecting every country in the world, and the competition has become the character of the world. The factor that determines the success or failure of competition is turning from several simple elements into a complicated system of elements, and the factor in the decisive role is changing fundamentally. City has become important in the globalization. Developing country can become strong as one segment of global production chain if she enter into global city net,or she will be abandoned out of the net bearing backward economy, large wealth gap, bad environment, unstable society. Therefore it makes a great sense to discuss urban competitiveness in the background of globalization. Correctly understanding the urban competitiveness helps the cities to exactly know their own situation, the strong points and weaknesses of their competitors and partners so that they can reasonably draw up the competitive and cooperrative strategy, which helps to compete for each other, to positively cooperate and to promote rational development. At the same time, it can help us to clarify the situation we face up .
 This paper starts from the foundation of urban competitiveness theory. After summarizing the predecessors' study, we give the definition of urban competitiveness, meanwhile, we analyse the intention and influence of urban competitiveness. Then considering the present economic situation of Liaoning province and according with the influence of urban competitiveness, we establish the evaluative index system and the study modal. After that, we analyse the advantage and disadvantage of different evaluation methods and find that subjective evaluation method is too subjective to determine the indicators' weights. Therefore we apply Rough Set theory. Using this theory we can reduce the scale of indicators system and calculate the indicators' weights. In the end, we can find out the things that prevent the city from developing and summarize some suggestions on developing the cities in Liaoning province according with our analysis results and the practical situation.
