摘　　要： 中国东西部地区之间不仅存在着城市化水平的差异,还存在着城市规模分布演进趋势不一致的特点。文章率先关注到这一特点,并从城市初始规模的视角入手,探讨和检验了国际贸易和区域内城市间运输成本对城市规模分布的影响。基于1998-2013年中国23个省区的DMSP/OLS夜间灯光数据等面板数据,文章发现国际贸易更有利于大城市发挥其规模经济的优势,获取更强的规模增长动力,从而推动城市规模分布趋于集中。进一步研究还发现省区内城市间的运输水平会影响国际贸易对城市规模分布的影响,在运输成本较高的省区,贸易开放会促使城市规模集中,而在运输成本较低的省区,贸易开放则会令城市规模分布趋于分散。在中国全面开放的背景下,改善交通基础设施有助于运输成本较高的区域避免大城市的过度集聚,实现大城市和中小城市的协调发展。 This study,for the first time,tries to explain the phenomenon that there exists difference in the city size distributions among the regions of China from the view point of cities＇ original scale. The paper examines how international trade and intercity transportation cost affect the city size distributions in China. With a panel data including the DM SP/OLS night time light data of 23 provinces in China from 1998 to 2013,this study finds that international trade has more positive effect on large cities and make city size distributions more concentrated. That is because large cities have more scale economics.M oreover,the paper finds that the international trade concentrates the city size distributions in the provinces w ith higher intercity transportation costs w hile it makes the provinces w ith low er intercity transportation costs more even. As China becomes fully open up,the improvement of transportation infrastructure among cities in provinces w ith higher intercity transportation cost w ill help to avoid over-agglomeration in large cities and realize coordinated development among cities.
