商品市场分割对我国增加值出口的影响——基于我国制造行业2001-2014年面板数据的分析

The Impact of Commodity Market Segmentation on China's Value-added Export:An Analysis based on China's Manufacturing Panel Data from 2001 to 2014

国内市场的分割现象是我国经济发展面临的现实问题,商品市场分割的存在阻碍了国内市场整合,在嵌入全球价值链的分工环境下限制自身比较优势降低了我国的出口潜力。通过引入距离因素,本文在修正我国商品市场分割指数计算方法的基础上,利用2001-2014年的行业面板数据,运用随机效应模型计量方法检验商品市场分割对我国增加值出口的影响,发现商品市场分割对我国的增加值出口具有抑制作用,这种抑制作用随着行业内国有企业比重的增加而更加明显。为了使我国在国际分工中更好地发挥整体比较优势,必须加快推进我国国内市场一体化进程与国有企业改革的步伐,并加大对全球价值链数据库数据更新及增加值核算体系研究的支持。

Domestic market segmentation is a real problem in China＇s economic development. In the context of the division of labor embedded in the global value chain,commodity market segmentation hinders the integration of the domestic market,limits its comparative advantages and reduces China＇s export potential. By introducing the distance factors,and on the basis of revising the calculation method of the index of domestic market segmentation,this paper uses the industry panel data from 2001 to 2014 and the random effects model to examine the influence of commodity market segmentation on China＇s value-added export,finding that the commodity market segmentation had a restraining effect on China＇s value-added export and was more obvious as the proportion of state-owned enterprises in the industry increased. In order to give full play to China＇ s overall comparative advantages in the international division of labor,we must accelerate the process of domestic market integration and the reform of state-owned enterprises,and increase the support to the global value chain database data update and value-added accounting system research.
