摘要
新一轮科技革命和产业变革下的工业高质量发展不仅取决于双循环新发展格局背景下的研发溢出,同时在很大程度上还受到全球价值链攀升的影响.本文构建了一个两溢出、两部门和三要素的2×2×3 开放经济模型,利用2000-2019 年中国工业动态面板数据估计了双循环新发展格局背景下的研发溢出对工业全要素生产率的影响效应.在控制研发效率等变量的影响后发现:随着创新的高质量转型,研发国际溢出的所有权优势引致的"市场攫取"提高了全球价值链攀升的成本,弱化了知识产品在邻近空间集群的空间关联性,对工业全要素生产率的改善作用不显著.全球价值链攀升有助于研发国际溢出的持续释放,在一定程度上强化了研发国内溢出的有效吸收,提高了研发溢出的内外关联性优势,对工业全要素生产率的改善具有显著的正向效应.上述结论具有深刻的政策含义:提高工业的高质量发展能力,除进一步化解研发国内国际溢出的制度性堵点外,更大程度上还取决于通过构建研发国内国际溢出空间协同联动的新发展格局,提升研发国内国际溢出在全球价值链攀升中对工业全要素生产率的空间引领作用.
Abstract
The high-quality development of industry in the new round of technological revolution and industrial transformation is not only dependent on R&D spillovers in the backdrop of dual circulation,but also largely influenced by the rise of the global value chain.This paper constructs a 2×2×3 open economy model which has two spillovers,two sectors and three elements,and uses China's industrial dynamic panel data from 2000 to 2019 to estimate the effect of R&D spillovers on industrial total factor productivity in the backdrop of dual cycle.After controlling the effect of variables such as R&D efficiency and so on,it is found that with the high-quality transformation of innovation,the ownership advantage of international R&D spillovers leads to"market grabbing",which increases the cost of global value chain upgrading,weakens the spatial correlation of knowledge products in adjacent spatial clusters,and has an insignificant im-provement effect on industrial total factor productivity.The global value chain upgrading contributes to the sustained release of interna-tional R&D spillovers,strengthens the effective absorption of domestic R&D spillovers to a certain extent,enhances the internal and ex-ternal correlation advantages of R&D spillovers,and has a significant positive effect on the improvement of industrial total factor produc-tivity.The above conclusions have profound policy implications:in order to improve the high-quality development capability of industry,it is required not only to further resolve the institutional barriers of domestic and international R&D spillovers,but more importantly,to build a new development pattern of spatial synergy and linkage between domestic and international R&D spillovers,and enhance the spa-tial leading role of domestic and international R&D spillovers on industrial total factor productivity in the global value chain upgrading.
