Abstract

[Purpose/significance] Energy storage technology is crucial for addressing climate change and promoting energy transition. A comprehensive examination of energy storage technology and its regional industrial development trends under the context of China's unified national market has significant practical implications for promoting the flow of scientific and technological innovation resources, facilitating achievement transformation, and narrowing regional innovation gaps. [Method/process] This research focuses on patent transfer data to investigate the evolutionary characteristics of technology transfer networks, firstly establishes a novel patent transfer record extraction model to detect technology transfer phenomena. Secondly, it employs the gravity center model to quantitatively analyze the spatial distribution patterns of technology transfer geographic centers and their spatiotemporal migration characteristics. Finally, from both micro and macro perspectives, it constructs and explores the structural features and evolutionary phenomena of bimodal sub-networks of energy storage technology transfer between innovation entities and between cities. [Result/conclusion] The research reveals that both inflow and outflow centers initially originated in Beijing, showing an overall southward migration trend, eventually stabilizing near the Yangtze River Delta, indicating that the energy storage industry's technology trading market is trending toward stability. The inter-entity transfer sub-network has gradually transformed from a sparse, dispersed network into a dense network with State Grid Corporation of China as the largest key node. The "enterprise-to-enterprise" transfer model plays the dominant role, necessitating further strengthening of the rising role of industry-university-research cooperation and recognizing the pivotal function of individuals in technology transfer. The development of provincial sub-networks exhibits a "small-world" characteristic,with an overall pattern of "strong in the east and weak in the west. "Each region should leverage its respective strengths and implement differentiated development strategies.
