Abstract: Strengthening the agglomeration of producer services can release huge productivity  effects; however, whether it can accelerate the development of new quality productivity remains  to be further studied. Based on the balanced panel data of 30 provinces (cities) in China from  2013 to 2022, this study constructs an index for new quality productivity. We calculate it with  the entropy method, referring to the three dimensions of new technology, new production, and  new industries. Meanwhile, adopting the dual-way fixed effects model, mediation effect model, and threshold model, we evaluate the economic effects of producer services agglomeration on  new quality productivity. The results indicate: ①Producer services agglomeration significantly accelerates the development of new quality productivity. In view of each refined dimension, it  significantly promotes the development of new technology and new production; however, no obvi⁃ ous impact on new industries. ②The impact of producer services agglomeration on new quality  productivity demonstrates a certain "Matthew Effect", where regions with higher levels of new  quality productivity tend to gain more from agglomeration effects. ③The threshold effect shows  that producer services agglomeration on new quality productivity has a non-linear increasing  "marginal effect"; while digital infrastructure, market-oriented development, and factor mobility  play a single threshold effect. ④Mechanism analysis indicates that industrial transformation and  upgrading, as well as technological progress, serve as mediating channels for producer services  agglomeration. In addition, industrial transformation and upgrading involves industrial structure  upgrading and rationalization, and technological progress is defined by low-risk technology ac⁃ quisition and high-risk technological innovation. Moreover, the development of e-commerce  strengthens the positive role of producer services agglomeration, playing a positive regulatory  role. ⑤Heterogeneity analysis shows that producer services agglomeration has a larger part in  the southern region, the areas of implementation of big data comprehensive pilot zone, and the  national innovative regions. Based on the above research conclusions, this paper proposes the fol⁃ lowing policy recommendations from four aspects. Firstly, it is necessary to strengthen the devel⁃ opment of producer services agglomeration, paying attention to improving its level and quality, as  well as allocating service industries to optimize its spatial layout rationally. Secondly, consider⁃ ing the inherent characteristics of agglomeration effect release, we should improve digital infra⁃ structure, coordinate the relationship between the government and the market, and facilitate the  flow of resource factors. Thirdly, it is vital to focus on technological innovation and industrial up⁃ grading, to alleviate the formation barriers for new quality productivity, especially emphasizing  the government's investment in technological research and development, and attaching impor⁃ tance to technological progress as the core driving force of industrial advancement. Fourthly, given the significant heterogeneity of agglomeration effects, new quality productivity should be  cultivated based on local conditions.
