A Study on the Spatial Linkage of Green Total Factor Productivity in Cities Along the Shanghai-Nanjing-Hangzhou High-speed Railway of China Based on SNA

Abstract

Abstract The Shanghai-Nanjing-Hangzhou high-speed railway is an important facility for the high-quality integrated development of the Yangtze River Delta. Based on the data of cities along the route in 2006, 2012 and 2020, Social Network Analysis (SNA) was used to analyse the spatial divergence and Based on the data of cities along the route in 2006, 2012 and 2020, Social Network Analysis (SNA) was used to analyse the spatial divergence and evolution structure of green total factor productivity (GTFP) of cities along the Shanghai-Nanjing-Hangzhou high-speed railway. that from 2006 to 2020, the GTFP linkages of cities along the Shanghai-Nanjing-Hangzhou high-speed railway have been increasing, and a network The study confirms that from 2006 to 2020, the GTFP linkages of cities along the Shanghai-Nanjing-Hangzhou high-speed railway have been increasing, and a network structure of green economic efficiency has gradually formed in nine cities; among them, Shanghai and Suzhou have the strongest radiating capacity, The green total factor productivity of cities along the The green total factor productivity of cities along the Shanghai-Nanjing-Hangzhou High-speed Railway has experienced an evolutionary path from monocentric to polycentric, basically forming a positive The cohesive subgroups of cities along the route have a certain degree of self-stability, and the cohesive The cohesive subgroups of cities along the route have a certain degree of self-stability, and the cohesive subgroups, mainly in the southern Jiangsu cities of Suzhou, Wuxi and Zhenjiang, are closely linked to each other in terms of green total factor productivity. Accordingly, suggestions are made to accelerate the development of green innovation in cities along the Shanghai-Nanjing-Hangzhou Accordingly, suggestions are made to accelerate the development of green innovation in cities along the Shanghai-Nanjing-Hangzhou high-speed railway.
