国内价值链构建、产品密度深化与制造业升级

Construction of Native Value Chains,Deepening of Product Density and Upgrading of Manufacturing

基于中国区域间投入产出表及工业企业数据,融合价值链和产品空间分析方法,实证国内价值链嵌入度提升对制造业升级的助推作用,分工地位低端化会给此过程带来一定阻滞效应。产品密度与制造业升级显著正相关,能够通过质的提升强化国内价值链对于产业升级的正向效应。运用门限回归方法证明劳动密集型、资本密集型和技术密集型制造业在产品密度门限值前后,国内价值链对产业升级分别呈现“分化效应”“收敛效应”和“加速效应”三种不同影响。我国制造业升级整体上要以优化产品空间结构为基础,将提升国内价值链分工地位为抓手,形成顶层设计与能力构建的良性互动。考虑到地区一产业异质性,应实行非均衡性发展策略,推动国内高端化“中心一外围”格局的形成。

Based on China’s interregional input-output tables and industrial enterprise data,the paper integrates the value chain analysis system and product space to prove embedding of the domestic value chain can promote upgrading of the manufacturing industry.Product density is positively correlated with the upgrading of manufacturing industries.Using the threshold regression method to prove labor-intensive,capital-intensive and technology-intensive manufacturing industries have differentiation effect,convergence effect and accelerating effect on industrial upgrading.The overall upgrading of China s manufacture industry should be based on optimizing the spatial structure of products,taking the promotion of the division of labor in the domestic value chain as a starting point,and forming a benign interaction between top-level design and capacity building.Considering the regional-industry heterogeneity,the non-equilibrium development strategy should be implemented to promote the formation of high-end"center-periphery"pattern in China.
