The Impact of New Quality Productivity on Industrial Economic Development—Empirical Analysis Based on Provincial Panel Data

Based on the panel data of 30 provinces in China from 2013 to 2023, this paper uses the fixed effect model to verify the direct mechanism of new qualitative productivity on China's industrial economic growth. The results indicate that: (1) New quality productivity is the main driving force for promoting industrial economic development, and further robustness tests are conducted by replacing core explanatory variables; (2) Selecting the agglomeration of R&D funding factors as its intermediary role in this process, and using an intermediary effect model to test the intermediary mechanism of funding factor agglomeration; (3) Through heterogeneity testing, it was found that there are regional differences in the impact of new quality productivity on industrial economic growth. The eastern and central regions have significant positive promoting effects, while the western region has no significant impact; Based on the research results mentioned in the article, relevant policy recommendations have been proposed, including increasing investment in scientific and technological innovation, strengthening talent cultivation and introduction, developing new quality productive forces according to local conditions, and alleviating regional development imbalances.
