Research on the policies of high-tech enterprises in typical regions based on social network analysis

Purpose This paper aims to quantitatively analyze the intergovernmental network structures within China’s high-tech enterprise (HTE) policies, with a focus on how these networks influence policy formulation and innovation support. The study seeks to provide both theoretical foundations and practical recommendations for optimizing the development and implementation of HTE policies. Design/methodology/approach Using social network analysis (SNA), this research systematically examines the interactive relationships among policy actors during the policy-making process for HTEs in four representative regions: Shanghai, Jiangsu, Beijing and Guangdong. The study analyzes the structural characteristics and dynamic evolution patterns of policy networks across these regions. Findings Regional economic development levels and innovation environments significantly influence collaboration models – taking Beijing and Shanghai as examples, both cities leverage their strong economic foundations and well-established industrial policies to foster favorable innovation ecosystems, thereby enhancing the synergistic effects of HTE policies. Fiscal and science and technology departments play a dominant role in HTE policy formulation, though their influence exhibits notable regional heterogeneity. Departments with structural hole advantages (characterized by high effective size and low constraint) often exhibit greater policy autonomy. This feature contributes to divergent HTE governance patterns across different regions. Originality/value This study innovatively uses SNA to deeply investigate intergovernmental policy network relationships within the context of HTE development in China. By systematically identifying the differentiated characteristics and underlying implications of regional policy networks, the research not only enriches the theoretical foundations of innovation policy networks but also provides significant insights for policy practice. The findings offer scientific evidence for policymakers to optimize governance frameworks, thereby more effectively promoting the sustainable development of HTEs.
