“大北京”规划设想的提出已近二年,理论界对环渤海、京津冀一体化的研究已有十几年。然而由于诸多方面的原因,这一地区经济发展仍不理想,与长三角、珠三角的经济实力存在较大差距。近期国家发展改革委领导提出“十一五”期间京津冀经济圈的区域规划,“大北京”将面临新的发展? The proposal of “Greater Beijing” has been put forward for nearly two years. The theoretical circle has been studying the integration of the Bohai Sea, Beijing, Tianjin and Hebei Province for more than ten years. However, due to many reasons, the economic development in this area is still not satisfactory and there is a big gap between the economic strength of the Yangtze River Delta and Pearl River Delta. Recently, the leaders of the National Development and Reform Commission proposed the regional planning of the Beijing-Tianjin-Hebei Economic Circle during the “Eleventh Five-year Plan”, and will “Big Beijing” face new developments?
