区域经济增长差异一直是学者们关注的焦点问题。本文利用信息熵和塞尔指数对京津冀都市圈1993～2003年区域经济增长差异进行量化分析，结果表明京津冀都市圈区域经济增长差距呈先缩小后扩大的趋势，在空间上主要表现为西北张承地区与京津唐地区之间的差距。引起京津冀都市圈区域经济增长差距的因素主要有自然条件、固定资产投资、外商直接投资和劳动效率等。

Regional economic growth disparity is the focus of scholars. In this paper，Family of Generalized Entropy measures and Theil Index are used to measure regional economic growth disparity in Beijing-Tianjin-Hebei Metropolitan Region from 1993 to 2003. Some conclusions are drown as follows： Firstly，When calculating economic disparity, different spatial unit gets different result in the same years and the same measure indices. At the same time, with different time to calculate economy disparity, the result is different in same measure indices. Secondly，from time sequence，the trend of regional economic growth disparity is earlier decrease then enlargement，and the spatial disparity represents between north-west Zhangjiakou-Chengde region and Beijing- Tianjin-Tangshan. Thirdly，the reasons contribute to regional economic disparity include natural condition, total investment in fixed assets, foreign direct investment and labor efficiency.
