| In the modern age,it is rapidly changing in external market and competitors emerge with various devices.It is also more difficult for departments to cooperate because of the expansion of internal business scale.Manufacturing enterprises are in a bottleneck period of development.At the same time,digital technologies and tools such as digital technology,industrial software,and big data are booming.It is the only way for manufacturing enterprises to break through the development dilemma and improve their innovation ability in the post epidemic era to quickly identify the changes of user needs and understand the dynamics of competitors in a digital way,and integrate data into the production business process as a factor of production.Therefore,this thesis deeply analyzes the mechanism and effect of digitization on the innovation ability of manufacturing enterprises,and tries to provide a meaningful reference for the implementation of digitization strategy in the manufacturing industry.Firstly,by combing and analyzing the relevant literature such as enterprise innovation capability and manufacturing digitization,this thesis finds that there needs to be improved theoretical and empirical research on the relationship between digitization and enterprise innovation capability.Secondly,taking the manufacturing industry in Shandong Province as an example,this thesis analyzes the current situation of the digital development of the manufacturing industry in Shandong Province and measures the digital level index of listed companies through the text mining method.Based on this,this thesis studies the digital implementation and digital level of listed manufacturing enterprises in Shandong Province.Then,based on the data value chain theory,enterprise innovation chain theory and enterprise absorptive capacity theory,this thesis analyzes the mechanism of digitization on enterprise innovation capacity and the regulation of absorptive capacity.Finally,it builds a DID model to verify whether digitization improves the innovation ability of enterprises,and builds a DDD model to test the adjustment effect of absorptive capacity,the adjustment effect of enterprise-scale,and the impact intensity of the four links of digitization of industrial design,digitization of manufacturing technology,digitization of organization and management and digitization of business model on the innovation ability of enterprises.It also tests the heterogeneity of the nature of enterprises through subsample regression.The robustness of the research conclusion was tested by parallel trend test,placebo test,PSM-DID robustness test,and substitution variable method.The study of the status quo found that there are some problems in the digital development of the manufacturing industry in Shandong Province,such as the large gap in the digital level of enterprises,the weak ability of information infrastructure,and the widespread phenomenon of data island.The measurement of enterprise digitization found that the digitization level of listed manufacturing enterprises in the different manufacturing industries has a large gradient difference,and the path of enterprise digitization transformation has its own characteristics.The empirical results show that digitalization can significantly improve the innovation ability of enterprises.The absorptive capacity of enterprises can positively regulate the improvement effect of digitalization on the innovation ability of enterprises.The digitization of business model and the digitization of manufacturing technology can significantly and positively affect the innovation ability of enterprises.The digitization of business model plays a prominent role in improving the innovation ability of enterprises.The digitization of industrial design and organization management has no significant effect on the improvement of enterprise innovation ability.And the implementation of digitization in state-owned enterprises and large-scale enterprises has a more obvious effect on the improvement of enterprise innovation ability.Finally,in view of the research results,this thesis puts forward countermeasures and suggestions to promote the improvement of innovation ability by implementing digitization from six aspects: highlighting the dominant position of enterprises,optimizing the policy environment,increasing the cultivation of high digital literacy talents,increasing R & D investment by multiple parties,strengthening infrastructure construction and strengthening data security. |
