Digitalization is an important representation of the transformation and upgrading of domestic industrial structure under the new development pattern of the national great unified market. From the perspectives of output and cost, it is constructed theoretically to analyze the influence and adjustment mechanisms of the digitalization level of producer services industry on the global-value-chain (GVC) position of manufacturing industry in China, and to make an empirical analysis based on the panel data of provincial manufacturing industry during 2014-2019. The results show as follow: Firstly, during the 13th Five-Year Plan period, the digitization level of producer services in our country has not yet fully exerted positive influence on overall GVC position of manufacturing industry, but shows a stronger positive impact in eastern and central regions, and industry competition plays a positive moderating effect on digitalization level of producer services and GVC position of manufacturing industry in eastern and central regions, and scientific and technological innovation ability plays a positive moderating effect in western and northeastern regions. Secondly, the digitalization level of producer services in our country positively promotes the rise of GVC position of capital-intensive manufacturing industry in the same period. Industry competition plays a positive moderating role in the influence of GVC position of technology-intensive manufacturing industry, but the moderating effect of scientific and technological innovation ability and institutional environment is not strong in the influence of GVC position of labor-intensive and capital-intensive manufacturing industries. This conclusion provides feasible policy focus points and optimal path selection for making use of the advantages of the large-scale domestic market in the stage of new development pattern and the double-cycle- driven high-quality development of domestic industry digitalization and the implementation of regional heterogeneous adjustment measures.
