Analysis on Technology Catch-Up of Advanced Manufacturing Cluster in Jiangsu Province from the Perspective of "Dual Circulation" Development Pattern

At present, the domestic and international economic situation presents an unprecedented complex pattern, in this context, President Xi Jinping put forward the concept of "domestic and international double cycle", which emphasizes the need to give full play to the advantages of China's super large-scale market and internal potential. As a large manufacturing country, China still has a certain degree of technological gap compared with some developed countries, despite the current momentum of the development of relevant industrial clusters. Therefore, as the most remarkable manufacturing industry in China, it is more necessary for Jiangsu Province to follow the premise of the new pattern of "domestic and international double-loop", and firmly take reform and innovation as the fundamental driving force to promote the technological catch-up of China's manufacturing clusters with developed countries, so as to narrow the technological gap with developed countries and finally achieve the goal of surpassing them. Based on the new development pattern of "double cycle", this paper discusses the development trend and catch-up target of the relevant industries from the perspective of the technological catch-up evolution of advanced manufacturing clusters in Jiangsu Province, and selects 10 key industries from which to measure the TFP of these 10 industries using DEAP2.1 software. At the same time, the findings of this paper are of some significance to China's exploration of the path and mechanism of upgrading the advanced level of manufacturing clusters under the perspective of "double cycle"
