流通活动、市场分割与国内价值链分工深度

Distribution Activities,Market Segmentation and Depth of Production Fragmentation in Domestic Value Chain

在发挥地区优势的基础上深化国内价值链分工,是提升"中国制造"整体竞争力的重要途径,而流通活动、市场分割对这一过程有着重要影响。本文测算了中国各大区域的产业分工深度,并对其影响因素和作用机制加以考察。结果表明:中国的区域间分工深度整体呈上升趋势,但在"入世"及"次贷危机"之后出现了下降。商流活动能够支撑地区间分工链条的延伸;物流基础设施促进分工的作用既有可能体现在地区间,也有可能仅限于本地区。市场分割会干扰跨地区经济活动的开展,其表现在于妨碍促进地区间分工的因素发挥作用,并强化不利因素的阻碍效应。未来应在基础设施建设中更加注重跨地区运输的要求,同时发展中间商环节、消除行政性壁垒,以统一、整合的中间品流通市场支撑现代化的分工生产方式。

Deepening the division of labor in domestic value chain on the basis of regional advantages is an important way to improve the overall competitiveness of“manufacturing in China”,and the distribution activities and market segmentation can have important impact on this process.This paper estimates the depth of production fragmentation in major regions of China,and studies the influencing factors and mechanism.The results show that the depth of inter-regional production fragmentation in China is rising on the whole,but has declined after China s entry into WTO and the sub-prime mortgage crisis.Activities related to business flow can support the extension of the inter-regional production fragmentation;in some cases,the construction of logistics infrastructure may promote the division of labor between regions,but the effect may also be limited to the local area.Market segmentation will hamper the inter-regional economic activities,preventing the role of factors in promoting inter regional production fragmentation and strengthening the hindrance effect of adverse factors.In the future,more attention should be paid to the requirements of trans-regional transportation in infrastructure construction,and at the same time efforts should be made to develop middle-man based business links and eliminate administrative barriers,with a view of supporting the modern production fragmentation with a unified and integrated intermediate goods market.
