Abstract: A unified domestic market plays an important role in regional specialization and contributes to scale effect. This paper uses price method to calculate the degree of commodity market segmentation for each city from 2001 to 2015. This paper finds that: (1) Except for shortterm increase of commodity market segmentation in 2008—2009, the degree
of commodity market segmentation has declined during 2001—2015. (2) There is a clear gap in the process of commodity market integration among regions. The level of commodity market integration in the southeastern region is higher than that in the western region. The level of commodity market segmentation at national level is greater than that at the local level. (3) Interregional competition encourages local governments to intervene in market, and thus aggravates commodity market segmentation; while better economic development conditions and market size expansion reduces vicious competition between regions and promotes regional commodity market integration. (4) Commodity market segmentation at city level shows a certain pattern due to the influence of administrative divisions: provincial boundaries hinder trade between cities and incur commodity market segmentation.

摘要: 统一的国内大市场对区域专业化分工和发挥规模效应起着重要作用。本文采用价格法系统测算了2001—2015年间各城市的商品市场分割程度,并考察了影响商品市场分割的地区因素。研究发现:(1)除2008—2009年商品市场分割短暂加剧以外,2001—2015年间商品市场分割程度整体呈现下降态势。(2)各地区在市场一体化进程方面存在明显差距,东南部地区的市场整合程度高于西部地区。全国层面的商品市场分割程度大于局部地区层面的市场分割程度。(3)地区间竞争会促使地方政府干预市场,加剧商品市场分割;而较好的经济发展条件和市场规模的扩大会减轻地区间恶性竞争,促进区域市场一体化。(4)城市层面的商品市场分割受行政区划的影响表现出一定的规律性:省界会阻碍城市之间的贸易往来,加剧商品市场分割。
