Abstract: The 14th People’s Congress emphasized digitalization as a key factor to promote the development of the resilience of the manufacturing industry chain, so it is crucial to strengthen the development and application of digital technology policy support. Exploring whether digital policies can effectively promote the development of the resilience of the manufacturing industry chain has become an urgent practical problem to be solved. This paper discusses whether digitization policy can affect the development of the toughness of the manufacturing industry chain and the degree of its impact. In theory, the application scope of the theory is enriched. In terms of practical significance, the first is to optimize the design of digitization policy as a reference basis for policy formulation. The second is to provide decision support for enterprises and enhance the management ability of enterprises. Third, it is beneficial to promote the efficiency of resource allocation and improve the return rate of R&D investment. Fourth, we can strengthen the coordination between the government and enterprises and promote the cooperation mechanism between the government and enterprises. Fifth, we can promote regional economic development and make targeted policy recommendations.
By collecting and analyzing the data of 1,993 listed companies from 31 provincial administrative regions in China from 2018 to 2022, this study constructs an evaluation index system for the resilience of the manufacturing industry chain, measures and analyzes the resilience of China’s manufacturing industry chain from the perspectives of high, medium and low industry chain resilience. The digitized policy texts of each province are retrieved and quantified by means of environmental, supply and demand policy tools. The relationship model of digitalization policy on the toughness of manufacturing industry chain is established, and the regression empirical test is carried out.
The results show that the overall toughness level of China’s manufacturing industry chain is on the rise, but it is still at the medium toughness level. The digitalization policy has a significant effect on the toughness of the manufacturing industry chain, but the demand-oriented policy has a certain inhibitory effect on the toughness of the manufacturing industry chain. The digitalization policy has a more significant effect on the toughness of the high-tech manufacturing industry chain, but the demand-oriented policy has a certain limiting effect on the toughness of the high-tech manufacturing industry chain.
We suggest we promote the synergy, service and intelligence of the manufacturing industry, and emphasize the key role of policies in promoting the transformation and upgrading of manufacturing enterprises. We should strengthen the implementation of supply-oriented and environment-oriented policies, reduce the restriction of demand-oriented policies, and promote the continuous presence of the combined policy effect. We should also adopt “special policies” to enhance the flexibility of independent development and innovation of high-tech manufacturing enterprises, and provide more policy support and guidance for high-tech enterprises.

摘要： 第十四届全国人民代表大会强调数字化作为推动制造业产业链韧性发展的关键要素,加强数字化技术发展及应用政策支持十分关键,探究数字化政策能否有效促进制造业产业链韧性成为亟待解决的现实问题。本研究首先通过收集和分析2018至2022年中国31个省级行政区包括1993家上市公司的数据,构建制造业产业链韧性的评价指标体系,并基于高、中、低产业链韧性视角对中国制造业产业链的韧性进行测度分析。其次,检索并获取了各省的数字化政策文本,采用环境型、供给型、需求型等政策工具对数字化政策文本进行量化。最后,建立数字化政策对制造业产业链韧性影响关系模型,对两者进行回归实证检验,得出研究结果并给出相关建议。
