摘要
国内产品市场一体化水平如何?本文利用中国区域间投入产出表的制造业贸易数据,在引力模型的基础上,以区域间贸易的边界效应作为国内产品市场非一体化水平的衡量指标,对国内产品市场一体化水平进行评估,并估计了产品同质性与投资的地方保护对边界效应的贡献。本文发现,区域间贸易的边界效应仅为7.31—7.61倍,略高于美国在1993年各州之间的边界效应,但远低于欧盟内部各国之间的边界效应;产品同质性对边界效应的贡献仅为12%—14%,而投资的地方保护成为边界效应的主要贡献者。上述发现意味着,国内产品市场没有处于严重的分割状态,通过消除外生的贸易壁垒,还能进一步提高国内产品市场一体化水平。
How about the integration of domestic market in China? Based on the trade gravid model, using the regionalinput-output table and taking the border effect as the index of regional non-integration, this paper estimates the level of the integration of domestic market and the share of product' s homogeneity and local protection which contributed to trade border effect. This paper finds that: the border effect is only about 7.31--7.61 between regions, which being slightly above the ones existing between the states of U. S. A in 1993 and being far below the ones within the E. U, the share of product' s homogeneity contributed to border effect is about 12--14% , and other shares of border effect is originated in the local protection of investment. These results indicate that there doesn' t exist the serious fragment in the domestic product market and there is the room of improving the level of the integration of domestic market through removing the trade barrier between regions.
