| 中文摘要: |
| 基于2017—2022年我国A股制造业上市公司数据，构建固定效应模型和门槛模型并实证分析数字化转型对制造业产业链韧性的影响。研究发现：数字化转型有助于制造业产业链韧性的提升，该结论在经过内生性检验和稳健性检验后仍成立。异质性分析表明，数字化转型对传统制造业产业链、西部地区制造业产业链和长江经济带制造业产业链韧性的提升作用更强。机制分析发现，数字化转型通过增强自主创新能力实现制造业产业链韧性的提升。进一步研究发现，研发投入在数字化转型对制造业产业链韧性的提升效应中存在单一门槛效应，随着研发投入的增加呈现边际递减的促进效应。 |

| Based on the data of A-share manufacturing listed companies in China from 2017 to 2022, a fixed effects model and threshold model are constructed to empirically analyze the impact of digital transformation on the resilience of the manufacturing industry chain. It is found that digital transformation contributes to the improvement of the resilience of the manufacturing industry chain, and this conclusion is still valid after the endogeneity test and the robustness test. Heterogeneity analysis shows that digital transformation has a stronger impact on enhancing the resilience of traditional manufacturing industry chains, manufacturing industry chains in western regions, and manufacturing industry chains in the Yangtze River Economic Belt. Mechanism analysis reveals that digital transformation enhances the resilience of the manufacturing industry chain by strengthening independent innovation capabilities. Further research has found that there is a single threshold effect of R&D investment in the enhancement of the resilience of the manufacturing industry chain through digital transformation, which shows a marginal diminishing promotion effect with increasing R&D investment. |
