中国区际贸易:数据获取与数据库构建

China's Interregional Trade: Data Acquisition and Database Construction

与中国国内区际贸易蓬勃发展相比,相关研究较为滞后,这种滞后在很大程度上源自国内区际贸易数据的可得性。在总结和厘清"金税工程"信息系统、铁路货运量数据、投入产出表以及估算法这四种现有数据获取途径的基础之上,甄选出一种能够更为系统全面地获取国内区际贸易数据的方法,即辅之以投入产出表的"引力模型加单一点估算法",并运用此方法尝试构建了一个包含1987、1992、1997、2002、2007和2012年28个省份36个产业的中国区际贸易数据库,从而为进一步的区际贸易研究提供了新的思路。

The domestic interregional trade of China has been developing prosperously; however, the related study is quite lagging behind, which is to a large extent due to the availability of the do- mestic interregional trade data. On the basis of summarizing and clarifying the four existing ways of data acquisition, i.e., the ＂Golden Tax Project＂ information system, the railway freight volume data, the input-output tables, and the estimation method, this paper picks out one method which can ac- quire domestic interregional trade data more systematically and comprehensively, that is, the method of ＂gravity model plus single-point estimation＂ supplemented by the input-output table. By applying this method, it tries to construct a China interregional trade database, which includes 36 industries in 28 provinces and in the years of 1987, 1992, 1997, 2002, 2007 and 2012, so as to provide a new idea for further studies on interregional trade.
