Delving into the spatial correlation network structure and driving factors of enterprises'new-quality productive forces is helpful to cultivate and strengthen new drivers of economic development.This paper takes A-share listed companies in the Pearl River Delta(PRD)region as samples,utilizes the entropy method to calculate the index of enterprises'new-quality productive forces,and conducts quantitative analysis on the spatial correlation network structure and driving mechanisms of enterprises'new-quality productive forces based on the social network analysis,the density-based spatial clustering of applications with noise(DBSCAN),and the QAP non-parametric estimation method.The results indicate that:1)The new-quality productive forces of enterprises in the PRD region exhibits a dual-core spatial clustering and multi-tier grading characteristic.The first-tier high-density areas are distributed in Guangzhou and Shenzhen,the second-tier sub-high-density areas are concentrated in Zhuhai,the third-tier medium-density core areas are centered around the Guangzhou-Zhuhai line and the surrounding areas of Shenzhen,and the fourth-tier low-density core areas are mainly distributed in the inland hinterland of the PRD region.2)The spatial correlation network structure of enterprises'new-quality productive forces demonstrates the spatial characteristics of small-world,network densification,long-tail distribution,and an"axis-hub"pattern.The network density and network efficiency exhibit an N-shaped trend(rising first,then falling,and finally rising again),with the overall network connectivity being relatively high.3)The spatial correlation network structure of enterprises'new-quality productive forces has obvious regional characteristics,the number of network nodes has steadily increased and formed a"2+N"community structure through cooperation,namely two main communities centered on Guangzhou and Shenzhen,and N sub-communities centered on Zhuhai,Zhongshan,Dongguan,Huizhou,which are distributed in an n-shaped pattern around the Pearl River estuary.4)Based on the nature of the spatial correlation network of new-quality productive forces,the sample enterprises can be divided into four plates.Plate Ⅰ exhibits non-reflexive structural characteristics and the role of a"net spillover"plate.Plate Ⅱ has reflexive structural characteristics and the role of a"primary beneficiary"plate.Plate Ⅲ and plate Ⅳ both demonstrate reflexive structural characteristics and the role of"bidirectional spillover"plates.5)Enterprise size,digital transformation,innovation capability,and ESG performance are key driving factors that facilitate the formation of the spatial correlation network of enterprises'new-quality productive forces.
