Research on the Radiation Effect and Collaborative Path of Xi'an as a Central City's Innovation Function against the Background of High-Quality Development

Abstract

Against the backdrop of high-quality development, this paper focuses on the radiation effect and collaborative paths of innovation function of Xi’an as a national central city. The study systematically summarizes the four-stage evolutionary characteristics of Xi’an’s innovation function from single-core polarization to networked collaboration, and identifies three major collaborative obstacles: administrative barriers, industrial isomorphism and innovation chain rupture, as well as gradient gaps in the innovation ecosystem. On this basis, a three-dimensional mechanism framework of “space-industry-institution” is constructed to reveal the spatial friction caused by topographic barriers and transportation infrastructure, the bonding effect formed by industrial complementarity, and the barrier-breaking role of institutional coordination. In response to the above obstacles and mechanisms, this paper proposes a collaborative path system that optimizes spatial carriers through the “米”-shaped transportation network and zonal layout, promotes the in-depth integration of innovation chain and industrial chain with the Qinchuangyuan platform, and breaks down administrative barriers via cross-regional governance mechanism innovation. The results show that the systematic promotion of spatial restructuring, industrial collaboration and institutional innovation can effectively improve the innovation radiation efficiency of Xi’an, and provide theoretical support and practical paradigm for the high-quality development of urban agglomerations in western China.
