Under the interaction of government regulation and market mechanism, the spatial correlation of regional economic growth in China has gradually evolved into a complex, multi-threaded network structure Based on the panel data of 30 provinces in China from 1992 to 2013, this article uses the gravitational model and the network analysis method to investigate the structural characteristics of the spatial association network of China's regional economic growth, and based on the weight of the space network to test the convergence of the regional economic growth in China. The research finds that: 1) The spatial correlation network of China's regional economic growth presents a complex and global development trend. The inter-provincial linkages show the coexistence of adjacent connections and jump connections. There are no independent development provinces, but the overall network is not tight enough; The connectivity and accessibility are strong, there are multiple overlapping spillover effects, and the stability of the network is strong; the network hierarchy has a significant downward trend, and the hierarchical structure of the spatial association network is not strict. 2) The degrees, proximity and intermediate centers of Shandong, Henan and Jiangsu are ranked in the top three, and they also have the most contacts with other provinces. They play the role of central actors in the spatial correlation network, and play the role of "intermediary" and "bridge" in the network. The provinces with the lowest degree of degree and near center degree are Jilin and Henan, and the phenomenon of mediation is 0 in many provinces. 3) The spatial correlation network of regional economic growth can be divided into four sections. There are general relationships within and between the four major sections. Among them, the impact of the spillover of the other sections of the sector II is the largest, and the relationship of the sector III to the other sections is the most. It plays a core role in the four sections. 4) The empirical results of convergence test show that there is a global convergence phenomenon in China's regional economic growth. Compared with the traditional spatial weight model, the convergence speed of the model is faster under the weight of the spatial network, reaching 0.07, and the spatial interaction between regions reduced the gap of them; the savings rate has a positive and significant impact on the economic growth rate, capital accumulation is still an important factor affecting convergence; in addition, there is a certain degree of club convergence in the eastern, central and western regions, the central region showed the strongest convergence trend, the convergence speed was as high as 0.101, and the convergence speed in the western region was the lowest, only 0.038. This reveals the important role of spatial network association in regional economic growth and has important theoretical significance for promoting regional coordinated development.
