生产性服务业数字化转型、空间集聚与制造业技术创新研究OACHSSCD

As an important part of the modernized economic system,the agglomeration development of producer services has become an important engine for the high-quality development of China's econo-my,while the biased configuration of the digital transformation in the industrial sector is changing the established effect of producer services agglomeration and bringing a positive impact on innovation de-velopment.Using the panel data of 30 provinces and municipalities in China from 2013 to 2022 as sam-ple data,the paper examined the impact of the digital transformation and spatial agglomeration of pro-ducer services on manufacturing technology innovation with a spatial Durbin model that includes mod-erating effects.The results show that:the digital transformation and specialization of producer services significantly promote technological innovation in manufacturing industries,while diversified agglomera-tion promotes technological innovation in local manufacturing industries but negatively inhibits it in neighboring regions.The digital transformation of producer services plays a positive moderating role in spatial agglomeration influencing technological innovation,strengthens the positive influence of speciali-zation agglomeration on technological innovation,and weakens the negative spillover effect of diversifi-cation agglomeration.This mechanism of action is realized through the transmission path of optimizing industrial structure.
