Abstract: Based on the manufacturing data of 11 provinces in the western region from 2015 to 2022, the Moran Index and social network analysis method combined with the modified gravity model were used to construct the high-quality development correlation network of the manufacturing industry, and the spatial structure characteristics and evolution rules of the manufacturing network in the western region were analyzed. The research results show that：1） The high-quality development of manufacturing industry in western China shows a significant positive correlation and is relatively stable according to the Moran Index. 2） Sichuan and Chongqing have a strong driving effect on the surrounding radiation, Xinjiang tends to develop independently, and Ningxia will stay at the edge of the network for a long time before 2022. 3） The network density and network efficiency of the high-quality spatial correlation network in the western region, obtained by using the improved gravity model, are generally on the rise. （4） The degree centrality of the network is gradually increasing, the inter-provincial connections are increasingly close, the intermediary centrality is also increasing, and the network structure is gradually developing toward equilibrium. Therefore, the high-quality development of manufacturing industry in the western region has significant spatial differentiation and unbalanced development characteristics, but the difference is gradually narrowing. Through the analysis, the following conclusions are drawn： the overall strength of the southwest region exceeds that of the northwest region, mainly because its economic base and infrastructure are superior, attracting a large number of production factors and promoting the rapid development of the manufacturing industry. Sichuan and Chongqing, as engines of regional development, have played a significant role in driving the surrounding areas, while Shaanxi is also gradually increasing its influence. Although Xinjiang and Ningxia are relatively backward, they have gradually improved their development level through regional cooperation and industrial transfer. Shaanxi has promoted industrial upgrading through scientific and technological innovation, Ningxia has accelerated the transformation of old and new growth drivers through industrial transformation and upgrading, and Xinjiang has made progress in equipment manufacturing, forming an industrial system with local characteristics. These development strategies and practices have provided strong support for the high-quality development of manufacturing industry in the western region.
