摘要

Against the backdrop of the deepening development of the knowledge-based economy, the traditional perspective focusing on knowledge stock struggles to explain the significant disparities in entrepreneurial vitality across cities with similar knowledge endowments, and the mechanisms through which knowledge complexity affects entrepreneurial activity urgently need to be clarified. Using data from 284 prefecture-level cities in China spanning 2000 to 2020 as the sample, this paper employs the GENEPY method to measure urban knowledge complexity, and empirically examines its impact on regional entrepreneurial activity, underlying mechanisms, and heterogeneous characteristics. The study finds that: knowledge complexity exerts a significant positive driving effect on urban entrepreneurial vitality; technological innovation and talent agglomeration are the core mediating channels through which knowledge complexity exerts its effects; there is pronounced spatial and industrial heterogeneity in this impact, with the promotional effect presenting a gradient pattern of “Eastern China > Central China > Western China”. Specifically, knowledge complexity has a prominent empowering effect on entrepreneurship in strategic emerging industries and productive services, while it exhibits a significant crowding-out effect on consumer services in the eastern region. This study extends the application boundaries of knowledge complexity theory and provides empirical evidence and theoretical support for the implementation of the innovation-driven development strategy.
