制造业投入数字化与国内生产网络关联

The Association between Manufacturing Digitalization and Domestic Production Networks

打通制约国内经济循环的堵点,释放国内生产体系动能,对建设全国统一大市场、构建“双循环”新发展格局的重要性不言而喻。本文基于2016版WIOD投入产出表数据,从制造业投入数字化视角研究国内生产网络关联问题。研究发现:第一,制造业投入数字化通过降低交易成本、延长生产长度和释放消费潜力三条途径显著提高了国内生产网络关联水平。第二,异质性分析表明,制造业投入数字化对国内生产网络关联的促进作用不仅仅局限在制造业内部,还对制造业外部生产网络关联产生了更强的促进作用,而且数字领域立法强化了制造业投入数字化对国内生产网络关联的促进作用。第三,进一步分析发现,人均国民收入在制造业投入数字化影响国内生产网络关联的过程中存在门槛效应。根据研究结论得到的政策启示,我国应加快推进制造业数字化进程,提高居民收入,完善制度性供给,打通上下游生产分工堵点,扩大制造业生产辐射网络,加速形成全国各产业协同发展和联动发展的新局面。

Removing the bottlenecks that hinder the domestic economic cycle and unleashing the potential of the domestic production system are undeniably important for building a unified national market and establishing a new"dual circulation"development pattern.This paper,based on the 2016 version of the WIOD input-output table data,investigates the relationship between manufacturing digitalization and domestic production networks.The study reveals the following findings.First,manufacturing digitalization significantly enhances the level of domestic production network connectivity through three pathways:reducing transaction costs,extending production length,and unleashing consumption potential.Second,heterogeneity analysis indicates that the promoting effect of manufacturing digitalization on domestic production network connectivity is not limited to within the manufacturing sectors,but also has a stronger impact on external production network connectivity.Moreover,legislative reinforcement in the digital domain strengthens the promoting effect of manufacturing digitalization on domestic production network connectivity.Third,further analysis uncovers a threshold effect of per capita national income in the process of how manufacturing digitalization influences domestic production network connectivity.Based on the policy implications derived from the researches,China should accelerate the process of manufacturing digitalization,raise household income,improve institutional supply,remove bottlenecks in upstream and downstream production division,expand the radiation network of manufacturing production,and expedite the formation of a new situation of collaborative and interconnected development among various industries nationwide.
