中国的贸易比较偏好

Comparative Bias of China's Trade

本文以中国5个年份30个省份的投入产出表为主,建立了包括省内贸易、省际贸易与国际贸易等指标的数据库,随后构建了贸易比较偏好指数进行测算。研究发现在1987-2007年间,中国的贸易比较偏好表现出如下趋势:第一,从全国范围看,各省对国际贸易的比较偏好程度大于对国内贸易(省内贸易和省际贸易)的比较偏好程度。第二,从不同区域来看,内陆省份更偏好国内贸易,沿海省份更偏好国际贸易。第三,从工业整体来看,各行业对国际贸易的比较偏好程度大于对国内贸易的比较偏好程度。第四,中间品行业更偏好国际贸易和省际贸易,而不是省内贸易;最终品行业存在着如下的比较偏好次序:国际贸易、省内贸易、省际贸易。

Mainly in the input-output table of 30 provinces of China＇s in five years, this paper first builds a sub- provinces and sub-industries database including intra-provincial trade, inter-provincial trade and international trade, and then find the trend of the evolution of trade comparative bias in China based on this database from 1987 to 2007, China~ trade prefer to show the following trends： First, Nationally, the comparative bias of the provinces on international trade is greater than the degree of comparative bias for domestic trade. Second, the inland provinces more prefer to domestic trade, the coastal provinces more prefer to international trade. Third, the comparative bias of various sectors of international trade is greater than the degree of comparative bias to domestic trade. Fourth, for trade in intermediate goods sectors, more prefer to international trade and inter-provincial trade. To some extent, the current division of labor in China is a nation-wide division of labor and world-wide division of labor. Fifth, for trade in final goods sectors, there is the following high to low order of comparative bias： international trade, intra-provincial trade, inter-provincial trade. This paper concludes that China~ trade comparative bias has the ＂befriending the distant and attacking the nearby＂ characteristic.
