新发展格局背景下国内国际价值链嵌入测度

Research on the Embedding Measurement of Domestic and International Value Chains in the Context of New Development Pattern

为完善新发展格局背景下国内国际价值链的统计测度和评价体系,使用矩阵转换法、混频动态因子模型测算全球与国内投入产出表,并运用增加值分解法构建指标体系,以依存度、嵌入度、嵌入位置测度新发展格局进程。研究表明:(1)中国在加入WTO后,对国外的依存度提升;(2)扩大内需战略成效显著,国内大循环主体地位逐步形成;(3)新发展格局促使中国向中高端加工环节转移,区域间专业化分工格局逐渐形成。国家须充分发挥市场在资源配置中的决定性作用,运用区域资源优势,提升生产专业化水平,畅通国内国际双循环。

In order to improve the statistical measurement and evaluation system of domestic and international value chains in the context of new development pattern,the paper adopted the matrix transformation method and the mixed frequency dynamic factor model to predict the global and domestic input-output tables.Meanwhile,the paper used the value-added decomposition method to construct the indicator system,and measured the process of building a new development pattern from the perspectives of dependency,embedding degree and embedding position.The results indicated that:(1)after joining in the WTO,China’s dependence on foreign countries has increased.(2)The strategy of expanding domestic demand has achieved significant results,and the main position of domestic circulation started to take shape.(3)The new development pattern has urged China to shift towards mid-and-high-end processing links.Besides,interregional specialized division of labor has also been gradually formed.Therefore,China needs to fully get the market to work,appropriately allocating resources and utilizing regional resource advantages,so as to raise the level of production specialization,and smoothly process domestic and international circulations.
