中国区域贸易增加值的特征与启示

Characteristics and Enlightenment of China’s Regional Trade Value Added

研究目标:刻画区域贸易增加值分配特征,分析区域分工"本地偏好"现象的可能成因。研究方法:编制区域嵌入国际的异质性投入产出表,构建区域层面的贸易增加值核算模型,计算分解区域参与复杂分工体系的增加值来源。研究发现:我国区域分工存在显著的"本地偏好"现象,双重价值链混合分工占比较低,国内区域间贸易发育尚不完善。进一步探索发现,区域外相对技术水平和贸易成本是"本地偏好"的可能成因。研究创新:将国家层面的贸易增加值分解细化到区域层面,为完整刻画区域增加值分配路径提供理论框架,从技术和成本角度再诠释"本地偏好"之谜。研究价值:为经济新发展格局下,畅通国民经济循环、解决瓶颈问题提供实证依据和决策参考。

Research Objectives:Characterize the distribution of regional trade value added,and analyze the possible causes of“home-bias”.Research Methods:Connect the Chinese regional input-output table and the world input-output table,and construct a regional trade value-added production accounting model.Research Findings:Chinese regional division of production strongly performs“home-bias”,the dual value chain division accounts for a relatively low proportion,and the development of domestic inter-regional trade is not yet perfect.The relative technical level and trade costs outside the region are possible causes of“home-bias”.Research Innovations:The decomposition of trade value added is firstly refined to the regional level,providing a theoretical framework for the distribution path of value added,and reinterpreting“home-bias”from the perspective of technology and cost.Research Value:Provides empirical evidence and decision-making reference to strengthen the national economic cycle under the new economic development pattern.
