Technological convergence performs as a technology development of inverse diversification. Based on the analysis of the innovation effect of technological convergence and technological diversification, and their relationship with economic development, the paper carries an empirical analysis of technological diversification and technological convergence in the field of ICT industry by Shannon-Wiener index and network analysis respectively. The conclusion is that in all, the telecommunications area and other ICT area have the highest degree of diversification, but Computers &office machinery area show higher degree of diversification from a dynamic perspective and fluctuate a lot. In the technological convergence study, H04L, G06F, H04B, H04M, H04Q, H04N, G01S, G08C, and H01L show a phenomenon of intra-industry technological convergence within the ICT industry, while H05K shows inter-industry technological convergence between ICT industry and other industry. Empirical results also show that the telecommunications area is most likely to produce technological convergence, so the R&D of telecommunications area has a huge role in promoting the development of other areas, and enterprises should pay more attention to the trend of R&D of telecommunications area and find the convergence area.
