中文摘要：

西北地区五省是我国西部大开发战略的重点发展省份,作为欠发达地区,城镇居民的贫困问题阻碍了城镇功能的充分发挥,成为制约地方发展的重要因素。通过对西北五省FGT贫困指数的测算发现,陕西贫困状况改善最为明显;甘肃和宁夏也有比较明显的减贫效果;青海成为目前西北五省中贫困问题最严重的省份;新疆贫困控制效果差,贫困问题突出。与全国相比,西北地区仍然是城镇贫困问题较严重的地区。实证分析的结果显示,经济增长和财政支出能够有效地降低城镇贫困,收入分配不均却加重了贫困程度。对西北地区而言,减贫不仅要追求经济效应,更应关注社会公平。

The Northwest region is very important area in China but underdevelopment.In this area,the problem of urban residents＇ poverty has hindered urbanization and become an important factor in local development.Through measuring FGT poverty index of five provinces in the Northwest,we found that： Shanxi poverty is the most obvious improvement;Gansu and Ningxia also got good results;Qinghai becomes the most serious area of poverty problem now;Urban poverty of Xinjiang becomes more prominent.The Northwest of China is still the area that urban poverty is more serious compared to the whole nation.Empirical analysis shows that economic growth can reduce urban poverty efficiently,but income distribution inequality has increased poverty levels.To the Northwest of China,the poverty reduction should depend on not only economic growth but also social equity.Based on the results,we propose some policy recommendations.
