Abstract

The ocean is a strategic place for high-quality development, and technology transfer is an important way to promote regional marine technology progress. Based on the perspective of patent transfer, this paper uses the data of national marine invention patent transfer in 2011, 2016 and 2021 to describe the spatial evolution law of national marine technology flow, and discusses its driving mechanism based on multidimensional proximity theory. The study finds that: 1) The scale of marine patents and the total amount of technology flow links have increased significantly. Enterprises have always been the main suppliers and consumers of marine technology. 2) The spatial gradient diffusion of inter-city technology flow from "dual-core drive" (Beijing, Shanghai) to "multi-core resonance" (Tianjin, Qingdao, Suzhou, Nanjing and other regional core cities) has changed into a national cross-level jump-type technology diffusion. 3) The multi-dimensional proximity analysis shows that the geographical distance has significantly reduced the hindrance effect on marine technology transactions.

Key words
