信息化是否促进了中国工业转型升级?——基于省际和门限特征的实证分析

Does Informatization Promote Industrial Transformation and Upgrading in China?Based on Inter-provincial and Threshold Characteristics

重点关注信息化发展对工业转型升级的影响这一现实问题。基于2003—2017年中国省际面板数据,实证检验了信息化对中国工业转型升级的影响强度以及可能存在的非线性约束机制。研究发现:信息化显著促进了中国工业转型升级,但存在区域差异,其中对中部地区的促进作用最大,东部地区次之,西部地区最弱;信息化对工业转型升级的促进作用呈现显著的边际效应递增的非线性特征,且在充分考虑市场化程度、两化融合水平和企业技术吸收能力的调节下,促进效果会进一步得到强化。研究结论为中国推进信息化与工业化深度融合、深入实施网络强国和制造强国战略奠定了理论与事实基础。

This paper focuses on practical issue of the impact of informatization development on industrial transformation and upgrading.Based on panel data from 2003 to 2017,the paper empirically tests the impact intensity of informatization on China's industrial transformation and upgrading and the possible nonlinear constraint mechanism.Studies suggests that informatization has significantly promoted China's industrial transformation and upgrading,yet regional differences existed.Among them,the promotion effect is most prominent in the central region,followed by the eastern region,and the western region at the bottom.The promotion effect of informatization on industrial transformation and upgrading presents a significant nonlinear characteristic of increasing“marginal effect”,and the effect is further strengthened under the adjustment of marketization degree,integration level of informatization and industrialization,and enterprise technology absorption capacity.The above research conclusions have laid a theoretical and factual foundation for China to implement the strategy of in-depth integration of informatization and industrialization and build a cyber power and manufacturing power.
