中国国家价值链的空间格局及其动态演进

Spatial Pattern and Dynamic Evolution of China’s National Value Chain

利用2002年、2007年、2010年和2012年中国30省份区域间投入产出表,从国家价值链NVC参与度、NVC复杂度、NVC合作度、NVC地位及参与NVC的增加值收益率5个维度系统考察中国国家价值链的空间格局及其演变态势。结果表明:(1)NVC地位较高的东部地区省份主要参与全球价值链(GVC)分工,地位较低的中西部地区省份主要参与NVC分工。与南部沿海和京津区域省份相比,中部、东部沿海与北部沿海区域省份的NVC合作度相对较高。此外,大部分省份的NVC参与度、NVC地位及NVC合作度均呈现不同幅度的上升态势。(2)基于投入与产出的NVC复杂度总体较高且持续深化发展,但位居NVC相对下游环节的省份逐步向NVC上游环节攀升,而位居NVC相对上游环节的省份却逐步向NVC下游环节下落。(3)中国各省份参与NVC的增加值收益率呈现出“中部地区较高、西部地区居中、东部地区经济发达省份较低”的空间格局,大部分省份参与NVC的增加值收益率趋于提升,具体呈现出先下降后上升的“U”形变动轨迹。

This article uses inter-regional input-output tables of China’s 30 provinces in 2002,2007,2010 and 2012,from five dimensions of national value chain(NVC)participation,NVC complexity,NVC cooperation,NVC status,and added value benefits of participating in NVC comprehensively and systematically examine the spatial pattern and evolution of China’s national value chain.The results show that:(1)The eastern provinces with higher NVC status mainly participate in the division of labor in the global value chain(GVC),and the central and western provinces with lower NVC status mainly participate in the division of NVC.Compared with the southern coastal provinces and the Beijing-Tianjin regional provinces,the central,eastern,and northern coastal provinces have a relatively high degree of NVC cooperation.In addition,NVC participation,NVC status,and NVC cooperation in most provinces have shown rising trends in varying degrees.(2)The complexity of NVC based on input and output is generally high and shows a trend of continuous deepening.However,provinces located in the relatively downstream link of NVC gradually climb to the upstream link of NVC,while provinces located in the relatively upstream link of NVC gradually landing to the downstream link of NVC.(3)The value-added return rate of China’s provinces participating in NVC shows a spatial pattern of“higher in the central region,middle in thewestern region,and lower in the economically developed provinces in eastern region”.The value-added return rate of most provinces participating in NVC tends to increase.Specifically,it shows a“U”-shaped trajectory that first drops and then rises.
