经济区域化是目前我国城市经济发展的根本趋势，考察各类城市参与经济区域化的获益程度及其影响因素具有很强的现实意义。本文借鉴Byrnes和Storbeck（2000）的方法，基于城市经济效率的视角，考察了长三角、珠三角和京津冀地区的区域化收益水平，并基于Tobit模型对影响区域化收益的各种因素进行了计量分析。结果显示，我国三大经济区的区域化收益存在显著差异，京津冀地区的区域化收益最高，长三角地区次之，珠三角地区最低。进一步的计量分析发现，专业化分工和技术研发能力有利于区域化收益的实现，而外资的引进、政府的作用和城市空间影响则扩大了区域化收益，多样化分工和对外贸易对区域化收益的影响尚不明确，分地区的计量分析也基本上得出了同样的结论。加强区域内与区域问分工，是实现区域化收益和提升城市经济效率的根本途径。
經濟區域化是目前我國城市經濟髮展的根本趨勢，攷察各類城市參與經濟區域化的穫益程度及其影響因素具有很彊的現實意義。本文藉鑒Byrnes和Storbeck（2000）的方法，基于城市經濟效率的視角，攷察瞭長三角、珠三角和京津冀地區的區域化收益水平，併基于Tobit模型對影響區域化收益的各種因素進行瞭計量分析。結果顯示，我國三大經濟區的區域化收益存在顯著差異，京津冀地區的區域化收益最高，長三角地區次之，珠三角地區最低。進一步的計量分析髮現，專業化分工和技術研髮能力有利于區域化收益的實現，而外資的引進、政府的作用和城市空間影響則擴大瞭區域化收益，多樣化分工和對外貿易對區域化收益的影響尚不明確，分地區的計量分析也基本上得齣瞭同樣的結論。加彊區域內與區域問分工，是實現區域化收益和提升城市經濟效率的根本途徑。

Economic regionalization is the essential trend of China＇ s urban economic development, so it is of a strong practical significance to analyze the economic gains and its influencing factors of cities participating in the process of regionalization. Referencing the method of Byrnes and Storbeck （2000） , the paper investigates the regionalization gains in the Yangtze River Delta, Pearl River Delta and Jing - Jin - Ji region based on the view of urban economic efficiency, and then analyzes various factors affecting regionalization gains based on the Tobit model. The results show that, regionalization gains have great spatial difference in three areas, and gains of Jing - Jin - Ji is the highest of all, followed by the Yangtze River Delta, Pearl River Delta being the lowest. Further econometric analysis finds that, specialization and technical researches and development capabilities help to achieve regional benefits, while the introduction of FDI, the government＇ s role and urban spatial impact expand regionalization gains and enhance the demand of regional cooperation. The influence of diversification division of labor and trade on regionalization gains is not yet clear, and the analysis of sub - region has basically reached the same conclusion. Enhencing regional and interregional division of labor is the fundamental way to achieve gains of regionalization and to improve urban economic efficiency.
